FIX THIS, HOTSHOT! Quote from another thread of mine:
"My personal situation is as such - ping response time is fast, download speeds good, but starting a sustained upload of pretty much any speed seems to totally 'disconnect' the modem, with the only way to regain Internet connectivity being to unplug the modem from the wall jack and plug it back in a minute or two later.
I've uninstalled/reinstalled the TCP/IP protocols on two different machines using the modem, switched through three good NICs, reformatted under Win2K and Win95 and had the line analyzed by an @Home technician for just under two hours onsite now...he and I both concluded that this is a result of a problem beyond my own system."
Further in-depth details available. Every time I call @Home about it they send me a new cable modem. I DON'T NEED A NEW CABLE MODEM!
It's frustrating. Got any ideas?
