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

  • Question
  • Updated 5 months ago
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!

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...

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 had this issue too. I was able to fix it by setting my computer's clock to the correct time, and then restarting.

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!!

My MCP connects to the connection, but nothing that requires an internet connection works. I have tried all of these suggestions, but they didn't work. I have been having this problem for a week now. I pay some bills online, I am having to use my parents iMac.

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.

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.

Not much help with the above comments eh! I was a Mac fan when my old Apple IIe came with 2mb ram and a 2mb hard drive - the thing NEVER crashed and did everything that was asked of it. Sorry can't say new Apple stuff compares. Apple joined the devil (microsoft for those who are slow) then beat the devil at his own bad ways. I hate to admit that my wife's second hand Dell XPS that cost nearly nothing has performed flawlessly for 2 years and she runs an extremely heavy program on it. Oh and it CONNECTS to the damn net too!!!! We all know that if the powers that be wanted they should have the ability to make something that works. Fact is they ALL chose not to, not enough dollars in upgrades to be made eh?

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?

if the clock issue isn't present check the DNS settings. I added the dns from the router and it worked immediately

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.

I've been having this same problem for a couple of days and discovered that if I use the private browsing function on firefox everything works fine. I still have no idea why this is the case but I hope it helps!
