Network cable unplugged...uhhh, no it's not

[Guest]

Hello,
For some reason my computer has recently lost the ability to "see" my cable
modem via ethernet. My service provider says they can see the modem on line
and that it has acquired an IP. My computer - through IPCONFIG, does not
show an IP. (I already purchased a new Belken ethernet cable to eliminate
that as a possibility)

I have installed usb drivers for my modem and have gotten back on line
that way, but I still have the LAN icon in the system tray saying "network
cable unplugged". Any ideas?

FWIW - My computer has always had a problem when I try to put it in standby
mode, so I've stopped doing that. However, for some unknown reason I tried
it again recently, and had to manually power down/restart to get it out. The
ethernet problem seems to have coincided with that. Not sure if that has
anything to do with my problem or not, but thought it may be relevant.

TIA.

Yes it got me to, dang cable modems running at 10 not 100.
Lock the port at 10 megabit/half duplex on advanced
properties of Ethernet.

It was set on Auto. I tried 10-1/2 and 100-1/2...no change. Back to USB.

It still says unplugged ?
You may have a bad Ethernet port on NIC or Modem.
do go bad sometimes. Newer Intel Nic drivers have diagnostics
built in to test for such problems.

I had 2 faulty motherboards with this exact same problem, it works fine
for a few minutes then boom no network cable appears, sent them both
back turns out was a faulty batch of nic cards. soon as i used a new
intel bog standard 10/100 it was fine o
