I’m frustrated

Why won't my MacBook Pro connect to the internet?

Why does my MacBook Pro not always connect to the internet via WiFi even when my iMac, which sits on the same desk as the notebook, does? The MacBook Pro connects to my home network, but it is unable to access the internet!

  • I’m confident.
    Alex,

    You might try the following fixes (probably in this order):

    Reset Safari (Click Safari at the top left, click Reset Safari, and make sure all the boxes are checked. NOTE: This will erase any autofill information you have stored as well as your browsing history.)

    Check your Date & Time. (If the date and time on your system is more than a few hours off of the actual time, your wireless router may not allow the computer to authenticate to the internet. If your Date & Time is incorrect, you can fix it by going to System Preferences and clicking Date & Time.

    Try reinstalling Safari. (You can download it for free from apple.com. Since you obviously cannot do this directly from your macbook, you may need to download it onto your iMac, then move it over on a flash drive or via target mode.)

    Try reinstalling the OS. (Reinstalling the entire operating system may fix the problem. You will want to back up at least your home folder(s) (user folders) before doing so. If possible, you may try an archive and install first, but this will only work if you have enough space on your hard drive to copy your user folders and then delete them. To archive and install, click options on the bottom left corner of the window before you install from the system discs.)

    Good Luck!!! Let me know if you have any further questions!

    I have a similar issue with my MBP. Connection to the network and Internet had worked fine for months using an Airport Extreme. Then, over time, I've noticed the connection to the Internet taking longer and longer, while connection to the network is fine (I can hit my network drives wirelessly with no problems).

    As of 2 days ago, I cannot get wireless access to the Internet on my MBP. My wife's Dell laptop can wirelessly hit the web.

    Any thoughts?

    By the way, @cjwinn: what does Safari have to do with accessing the web?

  • Resetting Safari clears out the caches of websites. These caches can slow down the internet connection and eventually halt it altogether. I know that it doesn't at first seem like it could stop the computer from connecting to the internet, but I work with MacBooks, and many times I have seen the problem completely fixed simply by resetting Safari.

  • I have the same problem on my iBook G4. I have reset Safari but still no connection. Am now in the process of restarting to see if this makes a difference. I'll get back to you on that one!

    This is what happened so far:

    I'm not a very techie person so am seriously running out of patience with my ibookG4. The situation is the following:
    (sure it's simple but want to give you as much info as poss for no confusion)

    I've had it since december 2007 (2nd hand) and have been using the internet at home on wireless ever since with no problem until about 8 weeks ago when the messages ...
    "Do you want the application "configd" to accept incoming network connections"
    and
    " Do you want the application "mdnsresponder" to accept incoming network connections"
    ...started to pop up. At some point i may have clicked no to this but for a while it was just an annoying procedure which meant network diagnostics and entering my password every time i opened Safari.
    However, the situation now is that i have airport signal at full strength, my home internet name comes up on the list of available networks, but when i open safari and type in a web address it says
    "You are not connected to the internet"
    When I perform Net Diagnostics is says that
    "Your network configuration has changed" (i am administrator and have not changed it and everybody else in my house, macs and pcs, don't have this problem)
    So, i type in the usual WEP password but it is not recognized - still no internet. I've tried turning router off then on - nothing. I called provider, they talked me through disabling airport and using ethernet which worked that day but not now after it's been off.

    This may have all coincided with me synchronizing my new iPhone to ibook or the installation of a new mac desktop to the network- it all happened around the same time and all other hardware still works fine.

    Anything spring to mind???

    Thanks in advance.

  • Right, no fix unfortunately. Wanted to avoid re-installing everything as i don't have all the necessary software :( But this is by far the closest i have found to my issue on my internet quest.
    I have found that when my laptop runs out of battery it resets its dates so that was rather curious - hasn't solved the problem though.
    I'll keep on searching through some fixes and any help will be greatly appreciated!

    Cheers

    • I am pretty sure you don't know me bcoz i don't know u either, I was looking for answers to how to connects the new macs to pre existing wifi's. I had the same problem when I bought my new mac book in 2010. From what I read and understand about these new macs is that they regularly upgrade their wireless cards periodically. However the routers that connect to the internet do not automatically upgrade. Also if u call Apple they would tell you to buy an Apple router which is ridiculously expensive.
      Coming to the point I would advise you to upgrade your router firmware only if u dnt have a linksys or Netgear router. I know these 2 router are pretty common but I am sorry to inform you that if u have one of these routers they would never work on Macbooks...the newer ones especially. So go out and buy a better router like a BELKIN one which might be just no more than $ 30 USD. If that doesn't work inform me in reply and I will see how can I make Macs more better...

  • I’m very sad and frustrated!
    Boy, deja vu! I just purchased my MBP the first of September of 2008. I have an Airport Extreme as well. Initially I was able to connect to the Internet with no problems. About two days ago I started having the exact same problem. (October 3, 20008) I have OS X 10.5.2. I too can connect to my local network but cannot access the Internet. This is so with both Safari and Firefox. The ironic thing is that I can go to any local hot spot (ie. Panera Bread) and everything works fine! In addition, I can connect to the Internet with my iMac and two other PCs. I became an Apple guy about 3 years ago and have been sold on Macs every since, that is, until now! This is my second MBP, the first one crashed the 2nd week I had it!
    • My problem is similar on a Mac Air, but generally limited to SSL sites, although some other sites (BBC, AOL) are very slow. Mine worked fine until about October, 2008 as well (using a LinkSys Router). The PCs on our home network are working without problems, but when the Air is on line they sometimes also slow dramatically... The problem must be related to software on the Mac itself? There are a lot of similar reports on the Net...

  • I've been having the same sorts of problems all day (and for intermittent periods over the past few weeks). Is your firewall set to "allow all incoming connections?" That seemed to fix mine, at least for the time being. You might also want to try resetting your PRAM, repairing permissions, or try using something like ONYX to clean out your system.

    I too.. like many of you have had the same problem with (1) of our Macbooks. It worked fine until just recently.... now we have to be within 30 ft. of the Airport Extreme for it to work. We have taken it in to the local Apple store and it always works just fine...We have taken it to our local Panera and there is never an issue getting online.... My son has a newer version Macbook at it has no problem connecting to the internet. I have a piece of junk Dell laptop from work.. and it has no problem connecting.... So we have tried the "Safari reset" and it seems to be working.... for now!!

  • Firstly turn off your router for 2 minutes - that will clear any issues there. If you have a 802.11n router then have you the latest AirPort firmware on your mac? Is it just your browser that doesn't work or do all web applications not connect? If its just your browser try installing Firefox or Opera?

  • I loaded Windows Xp on Parallels two days back on my Macbook and shared the Mac network connection with Windows network. All seem fine when I was working at home. When I reached office my internet stopped working through Ethernet port which is set up on DHCP. This network was working prior to installing Windows. I have uninstalled and deleted the Windows partition but still it is giving problems. I can ping my router but am unable to open any sites.

    Then I connected the Linksys AP and used the Airport. It worked perfectly for one day and now even the Airport is having same problem. I am having a Acer laptop and that is working perfectly on both ethernet and Wifi through its Windows Xp.

    What can be a problem ??

  • I have also been having this issue, although my MBP. I purchased about a month ago and never had any connection problems, then yesterday, I came home from class and was able to connect to my home network, but could not access the internet, and now I'm experiencing this problem on ALL networks I try to connect to. I've tried resetting everything, and spent 30 minutes on the phone with Apple to no avail. I have Windows Vista installed on my BootCamp partition and it has no problem connecting to any of the networks. Is there any fix other than reinstalling OS?

  • I had the same problem. Macbook Pro can connect to home network but not the internet. It started out with the clock screwing up when the battery died.

    Fix: I unplugged my airport extreme (did not reset) for 1 minute, then I used an ethernet to connect to the Macbook Pro, clicked on Safari, allowed outside connection, and it seems to be working. I even closed out and restart. So I hope the problem is fixed now.

    Shocker: I can't believe that Apple wants to charge for the 3 year protection plan to troubleshoot this problem, when it seems like a prevalent issue.

    I took my MBP to apple store to sort it out, as I have the same problem, It seem to loose the connection to internet and sometimes it cannot connect to router at all. The bad news is that apple do not seem to care, They have not heard of this problem and they wont sort it out as my laptop works fine as soon as i connect to their in store wifi.

    The annoying thing is that my HP works fine on my home wifi. so what the hell is the problem with the macbook. Is it a factory batch fault

    May be we should all go in to an apple store together with the same problem.

    Dose anyone have a solution. Apart from resetting the router and internet connections.
    • i have the same problem. I have had it for the 2 years i have had my MMP and my airport express. The MBP connects fine only until some other device connects to the wireless. Then the connection slows down and disapears. I can tell when my Iphone is checking for email - itcaues MBP to lose wifi connection. I have to turn off the Iphone wireless when i want to use the MBP.

      Tech support (which i pay for) can figure out nothing. It only happens in my home with airport express.

      I am sure johnnyspeed s right. operater error. the error was buying Apple

  • If it works fine with other connections then it is not your laptop just your router or the way you are connecting to the router. Buy a new router like the Netware DG834G

    Overall it sounds like user error to me. I've used 8 macbooks and macbook pros - every time this comes up as a problem with colleagues it is the user not selecting the right encryption type for the network they are connecting to or something really simple in the settings.

    Read my post above about resetting your router then the best advise I can give is RTFM.

  • I’m helpful today.
    A decent new router is like $60 - imagine the pain you could have saved by just swallowing your pride and swapping out your router. You must have a mate who you can borrow on off for the evening to prove whether its a faulty Airport or not.

    The fact that you take you MBP in and they say its fine suggests that its another link in the chain.

  • I've had a similar problem to many of these people,
    My boyfriend also has a macbook pro that he's had since september and his works perfect, however in the past month or so I can only connect to the internet if I am sitting very close to the router, or randomly somewhere else every few days..

    My computer connects to the internet fine anywhere else.

    It is not my browsers, and the router works fine,
    it is, indeed, the mbp itself.
    and this problem only started a little while ago.

  • I've had the same problem (running a macbook 4.1). I suspect it's a clock issue as cjwin suggested.

    - Couldn't connect to the internet when running windows xp via bootcamp
    - noticed the clock was off by a few hours
    - rebooted into OSX noticed clock was still off by a few hours
    - couldn't connect to the internet
    - set correct time on the clock
    - couldn't connect to the internet
    - shut my computer off for a day
    - when I finally dared to turn it back on, I connected to the internet just fine.

    Is it possible that bootcamp is doing something to the clock? Do other users with this problem use windows xp via bootcamp?

    This is happening with my Mac 10.4.11. The thing is, it works fine ( mostly) at home, but I am currently house-sitting and it suddenly won't connect to the internet. I have full signal, but safari OR IM programs won't acknowledge it. I've made the clock right, reset safari, reset the computer and turned off the router for some time. I'm not very computer litterate so the other reccomendations are flying over my head.

  • HI. I am having a problem, where Safari and Firefox just sit there turning over on a webpage when connected via ethernet and never get anywhere. It was working fine then stopped 2 days ago. As soon as I take the cord out, both browsers show a 'Not Connected to the internet page'. Also Skype works fine, I can receive calls and call out, so the internet is definately working, but something is wrong somewhere for the browser.

  • I had the same problems with my MBP with connections at home (works elsewhere). I tried resetting my router but that only helped temporarily. When I set my dual band router to G only, things cleared up. I also had problems with my home connection with my iPhone 3GS until I changed it over. Can't explain why it works, can only tell you it did for me. Good luck.

  • Go to your router setting online. For my Linksys there is a 'wireless' tab and under that 'basic wireless settings'. Mine is a dual band (B and G) and there is a "mode" option that allows me to set it to either B, G or mixed. I think setting it to either B or G will work, I just happened to choose G. Hope that helps.

    I've been having this same issue with my new Macbook Pro, which is my work computer. It would connect at work and at other Wifi public areas, but NOT at home by wifi or ethernet. After our IT department had no solution to fix my problem I ended up troubleshooting the issue myself! What ended up working for me was this:
    Go into the System Preferences window and open Network settings. Under advanced options get to the DNS tab. Here you can add/subtract DNS addresses. I basically put in my router address, saved it and the internet FINALLY connected via WiFi.

    You can also visit this link to help you find your DNS address. It helped me tremendously! Hope this helps!

    Hi all I have fixed my issue and been working fine for over a week now. It seems after all that, all I had to do was select a new wireless channel. Here are instructions.

    Go to internet browser and type 192.168.1.1 it will prompt for the password. leave the user blank and type admin in the password. Linksys setup page should open. now click on the WIRELESS TAB and on the basic wireless settings change the wireless channel to 11. I think you can also change to channel 1 or 2 if 11 doesn't work.



    Good Luck
    • This has worked perfectly for me for the last few minutes, not getting my hopes up though of it solving the problem indefinatly.

      Ridiculous problem to have after spending £900 on a mac! Perhaps not Apples fault but I think they should have a solution like this easily available to the user. Thanks very much for the help!

  • I’m pleased
    I just reset the PRAM by switching my Macbook Pro off and before the gray screen loads press and hold the options button, command, P and R.

    My Mac made the load up sound again. Once it fully loaded, all of the wifi I used to see before came back.
    • Just reset the PRAM and viola! it works, I had also rebooted the modem and router for the third time. That didn't work the first two times so I'm thinking the PRAM reset did the trick. I used to have to do that reset often with my old G series Macs, I think this is the first time I've had to do it with an Intel MAC.
      Thanks Sheridan Wynter

  • I’m SO GLAD!!!
    MY ROOMMATE FINALLY FIGURED IT OUT! and it was just a random shot in the dark too...

    Don't listen to any of the other crap on other forums. Here are the two things you must do. It's really quite simple... just something nobody at Apple was able to tell me. I only tried it in WEP encryption because it worked, so I stopped trying. Not sure how it works with other encryption.
    n
    1) Change the configuration of your router so that the MAC address if set to "default"
    2) Whatever your password is, put a "$" in front of it (without the quotation marks)

    Should work... did for me... thank god... wheeeew.

  • Ok man, I just bought an imac. Right out of the box and it will not connect to my net. Not wirelessly or by ethernet cable. And I'm using what is called CDE Lightband.. which offers no IP address. It's through my electric company. Anyway.. this sucks. Brand new computer and not able to use it.
    • TOTALLY SUCKS. I know. Which is why I'm not buying an imac
    • So whats the latest status on your Mac / CDE Lightband?

      Sounds like your Lightband is like my Clearwire modem. If that is the situation, then you know that you cannot connect wirelessly directly to the Lightband modem, but rather directly from the MacBook by means to the RJ-45 ethernet cable. That being said, this means that you have to buy a wireless router and connect the lightband to that. From the router, then you can connect 1 or more PC's to your internet service either by ethernet cable or hopefully by means of apples wireless signal. Talk to your lightband tech support and explain to the them what you want to do, Im sure they can help you out to make that happen. What wireless router to get? get the folks at CDE Lightband to make that call. If you still strike out, then post a message.

  • Buy a PC. All computers have problems, the difference is windows-based machines have people that know how to fix their problems.

    Every time I move or get a new router or new DSL service this happens. MACS SUCK when it comes to painless wifi connection. SUCK. I've reset the PRAM, typed in the IP address, and nothing. It will work with the ethernet cord, but not wifi.

    You'd think Apple would provide a step-by-step solution...but no...they charge $75 for any help. And CenturyLink, formerly Embarq, is clueless. NO ONE SERVICES MACS...except Apple - to the tune of hundreds of dollars a question. So lame...

    • You would think so .. but so many times i have seen folks overlook the basics when troubleshooting... like confirming that the power cord is plugged in when complaining that their computer is dead and wont power up.
    • couldnt agree more :-(

  • My experience and testing seems to confirm that it is not all Apple's fault. Not all the WiFi routers follow the same standards and rules. Everybody wants to tweak it a bit. That is why there are so many versions of JAVA and HTML even though there are specific standards they are supposed to follow.

    Usually a restart has worked for me.

    Don't like it but it is.

    Well, it has been over a year. My initial issue was fixed for a short period of time by resetting my Airport router. A few weeks later my wireless connection started acting out again. This time I simply went and purchased a Linksys router and have not had a problem since.

    I too am having this problem. The real kicker is that I'm sitting here on my 5 year old MacBook connecting to the internet flawlessly while my 10 day old MBP won't even FIND the internet.
    I'm tempted to take the damned thing back and just keep pecking away on my old MB.

  • Ok, I think I've found a solution. It's quite simple, but it's been a nightmare untill I've found it. After following everything said here with no success, this is what I did:

    Open Network Preferences.
    Open the menu where it says "automatic" and create and name it.
    Save it.
    Make sure you select the new location instead of automatic.
    Turn off Airport and then back on.
    It connected to the Internet without problems.

    The issue I had: MBP used to connect to every wifi network over the world. For some reason, it didn't connect in Spain. Like some people here, I have bootcamp installed and Internet run smoothly when in Windows, including in Spain.

    Hope it helps!

    My 17" MacBook Pro won't accept cookies, it randomnly disconnects from wifi and Safari crashes constantly; this $ 3800- computer is pretty damn useless.
    I re-installed the system, checked it for malware, brought the computer to Apple service only to be told that all is well all the while the same problems persist.
    I have had Macs the past 10 years and although I never thought I'd say this, I'm going to switch to PC.
    Apple's customer service is dismal, their geniuses are no help whatsoever and their computers just don't work anymore; of course they would never admit to anything, no money back, horrible customer service and tons of attitude.
    Fuck Apple !
    All that is left to do is move on, sit back and watch Apple go under.
    • I'll give you $500 for this piece of junk! ;- p
    • Recheck your settings in SAFARI. in SAFARI, go to PREFERENCES then to SECURITY tab. I normally run with web content with checks in boxs for, ENABLE PLUG-INS, ENABLE JAVA, ENABLE JAVASCRIPT, and BLOCK POP-UP WINDOWS. Further, In the section entitled ACCEPT COOKIES, I have it selected to show ONLY FROM SITES I VISIT

      If SAFARI is crashing on you or running slow, try going to SAFARI > EMPTY CACHE. if this show little or no change, then I suggest you try the next step to RESET SAFARI.

  • My MBP has been connecting to my home wireless router for several years OK. Just this week it decided to stop connecting. My non-mac PCs can access the internet fine. Every time I try to connect, I crash our home network. I had Apple on the phone, but no luck. After testing out various combinations with the MBP, I have concluded that the network card (hey--I don't even know if there is such a thing on a MPB) has gone bad. Could this be the case? I can not connect hard wired directly to the router or to the modem, so it is not just an AIRPORT wireless problem. Any advice?

    Alright, this is very, very odd. I tried restarting the computer and the router-none worked. I tried resetting the PRAM and again, no luck whatsoever. I'm unable to get to the Lynski website--or however you spell that useless router's name--so I'm going to have to resort to finding some way to fix the computer without that sort of interference. I even tried refreshing the "license" or whatever that is...no luck. Basically, I tried pretty much everything suggested in this thread.

    This is the issue:

    Few days ago, I had a great connection! I was enjoying myself with some games, Facebook and the like. Then, yesterday, all of a sudden I'm unable to connect to the browsers (Firefox, Safari) but I let that go since it's happened before and usually fixes itself. If only.

    The next day, nothing, and I can't even connect to my messengers or anything else that requires a connection.

    Now here's the odd part for me: I can connect to it via ethernet in another room but the wireless is continuing to PMS. Sometimes, after it being cut off from my computer for a few minutes, I'll get intertnet for the start up of the browser...then it'll revert back to: "Server not found".

    I figured there would be a way to reset the wireless but nothing on the internet is helping since it just LOVES to point me to issues with objects that are wireless. Blegh.

    Yes, I'm a bit of a newbie to this whole deal and I've been trying to solve this all day. Anyone got any ideas? Something tells me I'll have to drag my father from his work and log onto the site to fix a few things. Meep!
    • If you are in an area that is cluttered with a lot of wireless devices like cordless telephones, or garage door openers, home or office automation appliances, then you will find that the mac will drop the connection. I overcame the interference with my cordless telephone, by switching telephones from a 2.4 ghz frequency to a 5.8 ghz. Depending on where you are at, even if you replace your appliances you may still catch interference from your neighbors. In a cluttered electronic environment, distance from the router, could reduce the range of reach of your wireless router.

    This seems to be a problem at or office only on snow leopard. We have PC's and 7 Macbook Pros and only the snow leopard macs drop internet even though the local network stays connected. I think it has something to do with the DNS as only the internet is affected. Leopard works fine and we have 3 access points on different channels (3,5,11) and snow leopard is the only culprit.

    Hey there,
    Go under your root folder, and go to library >> SystemConfiguration. If you move that folder ("SystemConfiguration") to your desktop (you'll need to enter the master password), you should be good to go.

    If that fixed it, trash the folder. Your OS should generate a new one.

    Cheers,
    Chris

  • I’m over Apple
    I've read all the posts here and have fought similar issues for 3 damn years and have tried EVERY fix offered here. I have blamed isp's before but see that it's the damn mac. Sometimes they work for a while but I think it's more a random thing. There is obviously something wrong with individual macs that apple wont recognise. It's not worth the gamble so now I'm due for an update I'm off to learn damn windows again. I used to despise Bill Gates but Apple have taken over for being the biggest A-holes in computer land! I'm making a conscious choice to become i-Free, oh how I hate those little i's and the crap prduced under great marketing
