Can a virus disrupt cablemodem?

[Thomas A. Horsley]

I often see this phenomena where my cablemodem internet connection will work
flawlessly at 6:30 in the morning, but as the evening comes (and presumably
more folks get home and turn on their computers), the speed will go down and
errors with things like DNS lookups timing out will start happening.

Last night it got so bad it took my router about 40 minutes to get a new IP
address from DHCP when I tried power cycling everything.

I'm wondering if there is some kind of virus someone on the same cable
network might be infected with that is disrupting all the traffic?

Or maybe it is just too many users on too small a pipe?

Just curious...

Its likely a combination of both. Keep your machines clean and complain to
your provider, keep records of when it happens, keep complaining.

If they dont get the problem corrected give them the boot. I've gone
through the process several times, the latest with my current provider
Comcast.net. In the beging it was very fast but in a short time it went to
hell. Took them about 5 month to get it corrected. That was about a year
ago. It went well for several months and then began to slow down again.
After two weeks of complaining I came home and its back to normal with ping
times back in the 20's and 30 ms range.

20's and 30's? I'd be ecstatic to have your latency problems.

20's and 30's are when its working. For a while I was looking at 300's and
lots of time outs. I dont know if if was a line problem or they booted
people running servers on home lines but its working well again in any case.
