Ever heard of a network card being able to detect a connection only when connected to a particular modem?
A newer computer, a HP Pavillion XP has a problem.
We have had ATT/Comcast Cable modem for a long time. Worked fine.
We use a Linksys 4 port router to share the internet connection with a older Win98se machine, worked fine.
Decided to try Verizon DSL (didn’t cancel the Comcast yet), a few problems at first, but then worked fine.
The XP machine got updated to SP2, lost the connection, after resetting the modem & router, seemed OK.
That night and the next day we had about 3 times that the connection got real slow, then eventually wouldn’t work at all.
The only way I have been able to get connected on the XP machine since has been hooking it up directly to the Comcast modem.
If I hook the 98 up to either modem, works fine!
If I hook the XP up directly to the Verizon DSL modem or with either modem through the router I get “a network cable is disconnected”.
This is all using the same ethernet cable (a new one since the problem started) plugged into the PC.
Updated the Realtek network card driver, no change.
Spent hours talking to Verizon no help. Got a new DSL modem from them, no change.
Spent even more hours over 2 days talking to HP, no help.
I uninstalled SP2, No change. Used device manager to uninstall the network card (about the 3rd time), no change.
We’ve always had (and kept updated) McAfee Antivirus, Zonalarm firewall, & Ad-aware on both machines.
Any ideas?
