For the past 2 weeks or so, my internet will randomly go out 6 or 7 times a day for about 5-10 minutes each time. I'm using a Netgear WGR614v7 with all the latest firmware and everything should be running smoothly but it's not. I've tried calling Time Warner Cable and they say that it's not a problem on their end and they don't know what is causing the problem.

This problem affects all computers connected to the router, whether connected with an ethernet cable or using wireless, it doesn't seem to matter. Resetting the router doesn't seem to fix the problem, but it does resolve itself in about 5-10 minutes like I said above. I've also tried factory resetting the router twice, and the problem still happens. The actual physical lights on the router all remain green when the problem happens also, there is no change in the color to indicate something has gone wrong.

It actually happened as of the typing of this very sentence and I'll try and show you an ipconfig /all

I've tried googling and nothing seems to come up with any similar problems or fixes. I try correcting the problem in the network and sharing center and it says that it doesn't know what the problem is and tough luck basically. If anyone has any idea what could be going on I would appreciate it.

Just thought I'd share my two cents.

I too also have RoadRunner through Time Warner Cable, and I have to say, more often than not, it's been their modem that is the problem. I had the exact same symptoms as you describe on one of my Linksys routers, and I swapped it out with 4 others and told them it made no difference and that I KNEW it was their modem, and they tried to keep blaming it on me, so eventually I gave up and went to the store and got a new modem replaced then and there and the internet worked just fine. I never thought a modem could cause so many problems, but many times with some of the more extended internet outages/drops, it has been related to THEIR modem.

So, I would say if a TW store is easily available to you, just go in there and swap out modems and see if that fixes it in.

I cant help you, but it can't be any worse then using my iPhone 3GS as a modem!

Have you tried running a computer directly off the modem to see if you have the same problem? If not, I'd do that - if you still have the same issue, tell them you want a new modem.

Call your ISP and move up to a tier that doesn't include rolling blackouts. You might get some more websites, too!

If the modem is failing, don't buy the same modem, obviously. You can usually buy your own modem of whatever make you want (so long as it operates on the same requirements your ISP does, I don't know the specifics of that though.) I believe there are frequency ranges that different Cable ISPs use. When I signed up for my service (local cable co) they said I could buy theirs, or buy my own as long as it met specific requirements that they had listed.

Someone on somethingawful was able to help me out. Turns out that the splitter that Time Warner also installed along with the modem (so my TV could have cable) was weakening the power level of the modem so significantly that my router was trying to reacquire a connection every time there was a minor fluctuation in power levels and a connection was dropped. It seems like the internet is now a bit faster too, although this may just be non-real perceived increase due to my happiness the internet is back to normal. Here are pictures of the power levels in case anyone has a problem like this:

Power levels before. "weakest possible signal allowed under the specifications. Even a minor deviation will force your modem to reboot to try to reacquire a connection."


And after:

You neglected to mention there was a splitter...

A lot of splitters used by Cable people (especially if the service is contracted out) are crappy. Sometimes you even require a power inserter, but those are expensive.

Yeah, usually you want to avoid splitting as much as possible. It also helps if you simply split it once before the modem. One line goes to the modem, the other can be split as needed for all your TVs. (Although with the digital age of cable, your cable box might not be too happy with poor power as well, unlike analog which could get much worse before noticeable interference)

Coaxial from older installations often can't handle the throughput needed to run digital tv and internet. It needs to be good enough that you can split the signal, and still have enough power in each branch to run both signals. Cable company might upgrade exterior cabling for free if you threaten to drop them. Interior cabling is up to you; depending on how it was installed it can be real easy or a real *****.

My house was built before the cable era, so I have attic-drop wiring. I had to go into the attic and replace all the splitters when I got an hdtv, so the hd tuner would work in the living room. Would be real easy to replace the wiring too. Just tie the new wire to the end of the old one, go up in the attic, and pull em up.

Hrmm, I have this problem also. I think I might need to go get me some new splitters
