'Net + Router = internet dropping. Assist from the tech-saavy please?

Just don't understand this problem, but it exists constantly.

I have Time Warner Cable high-speed internet access. Wall cable to high-speed modem, modem to directly injected to computer via ethernet cable. 100 Mbps speed which I'm using now. Works like a dream.

It's when any wireless router is put between the modem and the computer that the fun starts. Internet connection drops every 10 minutes or so and stays out for 5 minutes, then reconnects.

Cable guy has been out here 3 times and of course, everything works fine from his perspective even though 'net connection continued to drop on a regular basis while he was here. "Call the wireless modem company." Yes, I've called. No help.

So far, I've had a Netgear wireless router and two Cisco wireless routers on my Dell Desktop (used for photo editing and 'net surfing) and the same three on my HP laptop / Docking Station (work owned) system.

Same problem continues regardless of what computer is hosting and which router is used. Oh, and I've had 3 high-speed routers swapped in from Time Warner as well. All perform flawlessly when direct injected to either computer ... it's the wireless router that seems to be the issue.

Anybody else have this issue with high-speed internet service DROPPING regularly when a wireless router is introduced into the system? I'm at wits end to be honest.

In the meantime, more surfing to possible find a solution.

thanks for listening to me whine!

Shot in the dark but have you looked at this?

Yes, thanks. Been there and followed all the rules. The only strange thing is that both of my computers run Windows XP with service pack 2!

I'd start by checking how the I/P addressing functions, both from cable modem, and then from the Wifi router.
Presumably the cable modem is a DHCP server (assigns the addresses to the computer) - it's possible the Wifi router is also a DHCP server, and if this is the case and Wifi router is just bridging between wired & wireless networks then there'd be potential for conflicts.

If the internal addressing isn't the problem then you really need to isolate wether the cable modem is actually going off-line during the issue period, or wether it's only the computer's connection that's falling over. If you know the cable modem's internal address you can set up a continuous ping from your computer to the modem & see if it stops replying when the problem occurs.
start/run type in cmd and hit enter, type in ping <modems address here> -t and hit enter to set up continuous ping.
(Not sure what your level of networking is so apologies if the above sounds lame)

This is the second thing that crossed my mind.

Was helping someone with a similar problem on another forum; he'd replaced the cable modem 3x or so. He finally isolated the problem to a wonky power cord (he was changing the routers without changing the line cord). So you might try swapping around all the cables (not just the power cable). Remember Pournelle's First Rule. "It's always the cables. Even when it isn't the cables, it's the cables."

Thanks for the tip. I'll definitely try it. Appreciate your response.

PPPoE is for DSL, not Cable.

Yeah Jon, thanks. I've got a bunch of ethernet cables and am on the 3rd Time Warner Cable router as well. It's a bundled deal with phone, tv and internet. The phone and tv absolutely NEVER go out, great reception on both as well. It's just the 'net service!

When the cable guy was here Monday this week, the net signal is at the high end of allowable signal strength ... when it's working!

Plus, from working in bands most of my life and running sound, I can't disagree that problems are MOST likely caused by cabling or plugging something into an 'out' instead of an 'in.'

Is it all powered cleanly? By that I mean is everything plugged in to a new model working UPS?

It almost sounds like something is overheating, cooling down....

Complete SWAG....

If you're connected to a UPS disconnect it and connect straight to the outlet. We had an issue with the network gateway shutting down, turned out that the UPS was causing problems. Got rid of it and connected power straight to the wall, no problems since.

Ours did this...was the router..had to get a new one delivered.

Connected to a separate outlet in home office, not into a power strip of any kind. Recommended by cable guy.

It doesn't matter ... as soon as a router is introduced to the signal, it drops at regular intervals. Frustrating.

I've had three since Thanksgiving last year ... doesn't matter which one--same crap, different wireless router.

What brand and model modem is it?
