Consistent internet connection drops

I have this problem too and if you check my post there are several other people with the same issue. So far no resolution or follow-up from comcast. I'm going to call their resolution group at corporate again.

I just wanted to post my Comcast experience for all. Currently, trying to work it out with the local Comcast tech. He is still changing out my splitter and checking voltages, signal has improved but I still have drops. There may not be a solution here at my home. I am guess there is a repeater or box issue. Not my problem to solve and I can't comtinue to pay for this type of service. Even dial up is more reliable. Good luck with your issue.

I have this problem too. I thought maybe my router or modem is the problem. It happens every time I upload something. I tried calling comcast three times and I keep getting cut off.

Update: It's been 5 weeks of Comcast drop internet connections. Had 2 tech visits, changed out splitters, check/verify voltages and all terminal connections. Still getting drops at any given moment. Now by habit, I am keeping track of time of day and getting really good at reseting my cable modem. Looking into ATT now, they just installed a new optic line in my backyard.

This has been going on at my home (NW Boston suburb) for almost a month
now. Once or twice a week we lose internet connectivity; usually it goes out in the mid-evening between 8 and 10 pm and returns the next morning. As a former network system administrator, I can troubleshoot the problem from my
end and it's not my equipment. My cable modem could be unstable (which is unlikely), however, given when the outages occur, I suspect Comcast doesn't have sufficient bandwidth in my neighborhood during peak internet usage and is forced to drop connectivity from some of its users.

I have had this issue since hurricane Ike and they've had people here several times to fix it, they say it really never is. I finally downgraded my speed to rock bottom price because I'm not paying for what I'm not getting anyway, and they had just raised my price (again) for the speed I had with the lousy service. Fortunately I don't need a lot of internet speed. I feel sorry for the people who do if they have internet service like I have.

My reset, drop connections are occurring in South Bay San Jose, CA.
Left messages on my tech's cell phone and I will be calling his supervisor in the morning, to see if he has any clue on what is happening. I am guessing it's the repeater or node box. If I can figure this out, I should be working for Comcast. Talk about job security. There is a mountain of issues surrounding this topic of internet drop connections. Good luck all, I will be posting any updates on this, to hopefully solve your issue. Aloha, Mark

I'm in central Houston a minute from downtown. I have decided that I'm too busy doing battle with comcast about my TV to fight with them about internet, also. I might just move someplace with options. I feel like a hostage.

Welcome to the club......

yeah welcome to the club

looks like everyone has this problem. my connection has been dropping at anytime for over two months. there has been 3 times of tech visits and found nothing about the problem. what the fuck is wrong with comcast?
this is so fucking comcastic... terrble service.

Having Comcast is like the new Sprint commercials, with the people sweeping and throwing out their money. Half to no service connections with no one to return calls. My update to this topic is,,,,
Comcast area supervisor and Sr tech will be visiting tomorrow to check problem out. This will be my 3rd in house visit, they can not see that it's outside of the home, with their lines and equipment. What a waste of time and quality service. We'll see what happens.

Heather, it is not your modem or router, it is comcast who cuts your connection

My problem is weak to a very poor receiving signal. Try 192.168.100.1 in the address field of the browser. Mine is currently, -8 dbmv. Should be closer to zero. Terrible bandwidth, it gets worst with others login. I kept all times of drop connections. Looking for a refund for the month of May and June. Wish me luck with that.

Finally got communication from Comcast corp. They are using there so-called escalation process to solve my issue. Last week a Sr Tech came by to re-verify the problem and record it for the network dept. We will see if this gets solved by this week/before my new billing cycle on the 15th. I may have to switch off and go shopping for a new IPO. This power cycling is killing me, man.

Problem finally solved. After replacing the entire cable from my home to the utility pole, the techs (network and installation) found the root problem. There was a connection error/routing at the function box. They were not sure how and why would any one connect it that was. I am now recieving a +3 dbmv signal versus a - 7 dbmv. Also, the tv signal seems to be clearer. Good luck solving yours. Suggestion, if you think your main line is clean, have them climb the pole to check out their connections.

We just had a tech out this morning working on the same issues that EVERYONE is having. Guess what they did - replaced the splitters ! We all know it's on Comcast's end of things but getting them to check those connections takes forever. I was hopeful this morning but it sounds like my optimism will be short lived. Thanks Mark for the info 'function box' connection. I'll need it for ammo later I think.

Having the same problem at our client's office in Midtown/Houston. He is a Doctor who relies on the internet for some of his services. We have contacted Comcast, they changed out the modem twice just as said before, ran a new cable twice, just as said before and we are still experiencing the same problems. The only way to get the internet back is to reset the modem, I would think if it were a simple drop the modem would just come back on. I have been in contact with them again trying to get this resolved. Exploring options for new service.

I have been having the same experience in Sacramento, CA. Technicians came out at least twice before one person appeared to have fixed the problem. I didn't have drops for about a month, and lately it started happening again, sometimes three or four times a day. I am very frustrated with this kind of inconsistent connection. Unfortunately other options are either not available or more expensive at this point (problem of living in new construction). We need more competition! Otherwise there is not enough incentive for any provider to stop giving us poor service.

I am having a similar problem in Southwest Houston. Has been a nuisance for some time and getting worse. My Comcast (EarthLink) high speed internet cable connection is frequently failing to connect, dropping out, or so slow that I get the browser error that it cannot display the web page.

Even if the connection holds, there are often 10-15 seconds waiting until the web page finally starts appearing.

On many of these occasions the "Cable" light on the modem begins blinking and often goes dark. Sometimes a power off/power on cycle will get the connection back. I have tried power off + restart computer + power on and the problem reappears within minutes.

My cable modem is a Toshiba PCX2500.

I have now written to the email address given above:
We_Can_Help@cable.comcast.com and will see if I can get some help.

I had a similar problem of unexplained drops for a long time. I could normally re-connect by unplugging the cable modem and plugging it back in. The culprit was my TV. It was leaking voltage out the tuner and down the coax which ran to the splitter my cable modem was on. The voltage was messing up the modem - thus the drops. The fix was put a 2X splitter on the inbound cable, 1 out goes to the cable modem and the other goes to a grounded multi splitter for the TV's. This did the trick for me.
