Computer problems, what to do?

My internet is going out a couple times a day. I have to unplug the cable modem to bring it back up. Where should I start? What should I look for?

I've been having problems for a few months now but just recently has it got worse.

For starters

In reply to: Computer problems, what to do?

For starters, if resetting the cable modem resolves the issue temporarily, that would be a good place to start. Also, I have known it to happen that if you run file sharing programs on lower end routers, you basically end up causing them to run out of memory from all the activity, and then this sort of thing can happen.

So if you have any kind of file sharing program running you should probably stop, or at least learn to reign it in to avoid these issues. Otherwise, I would probably start by getting another cable modem and/or calling the cable company and getting them to verify there's no issue with the physical connection between the neighborhood hub and your place.

Thanks for the reply. I don't run any kind of file sharing program that I can think of. At various times I have a laptop, desktop, google tv, xbox live running. I bought the Netgear N900 a couple weeks ago to speed things up, also upped the cable plan because the wife bumped us down to the lowest of the low. So now I'm pretty good with speed but losing the net quite a bit. It has seemed to of gotten worse since the new router, could that be part of the problem even though it's supposed to be a really good router?

Must always use your I.S.P.'s cable modem.

Plus, use that router to distribute the LAN connections between the XBOX, PC and, Laptop. Google TV should only be used by the PC.

Make sure to use only one unit at a time via your one and only one connection allowed by the I.S.P. Multi-connections will make the I.S.P. think that your are trying to make a connection share/splitting. If you are doing such connection share/splitting, the I.S.P. will temporarily cut-off your service just for the heck of reminding you, not to do that.

Are your RJ-45 port's chipset been updated/upgraded in its latest Device Drivers for both PC and Laptop? That happens if such LAN chipset gets a little bit on the aging status. Happened to me quite a little bit too many times.

Hope that helps clearing things out.

Your new Netgear N900 ...

In reply to: Thanks

could indeed be part of the problem as it is dual band and its 2.4 GHz band provides worse than normal performance. Are your peripherals 5 GHz capable?

The problem could also actually lie with your actual MODEM that plugs into the WAN port of that router.

You also didn't mention the OS in use that is having the problem. I have often seen a Windows 7 computer that had trouble maintaining a connection to a router that XP and Vista and even old NT boxes were getting solid connections on. Updating the NIC or its drivers on the Win 7 box usually helped a lot.
