When I check my network connection my LAN-connection is listed with a red X and an error message saying that ?a network cable is unplugged? (no true in my opinion). I can see that my LAN-connection is flashing very briefly every 5th second (computer receives an ip-adress) but the red X returns immediately. For some reason my computer/network simply refuses to accept the ip-adress sent.
For your information:
My computer is connected directly to a broadband modem with the correct type of cable.
The connection worked great some days ago, but not anymore.
Have tried system restore without success.
Checked the status of the network cards in device manager. No question/exclamation marks.
Have uninstalled the network card and its (most recent) drivers and of course reinstalled it too.
No firewalls or any other potential internet obstacle is installed.
No new hardware or software has recently been added.
DHCP is enabled on the computer and should be so according to ISP. TCP/IP settings are correct.
Tried reseat network cable.
Tried another network cable.
Tried another network card.
Tried in another pci slot.
The ?sync, dsl. @? led on the modem is lit, indicating that the modem is working fine.
ISP says no problems in the network.
The only thing I have done (and is reluctant to try) is to reinstall the OS.
Any tips on what I should try next (before reinstalling everything and accepting that I can?t find the problem)?
