I'm running Windows 7 64-bit.
Evaluation version 7100.
The driver for the ethernet connection is some sort of Intel driver built in with the Dell E520 Motherboard.
The thing is, the wireless works. I use a D-Link Xtreme N Desktop Adaptor (DWA-552).
But my computer is in such an awkward location in the house that it's not really an excellent option, so I got 20m of ethernet cable to hook up my PC to the router which is a D-Link DI-614+.
The Router and modem are connected to a PC that is running Windows XP.
When I plug in the cable to my computer it sorts it out for a while but it ends up saying it doesn't have a valid IP address?
This only occurs with the ethernet cable and not the wireless.
Could this be a case that my computer is too advanced?
What if I rolled back to 32-bit or XP?
The drivers for the DI-614 are already at the latest, and D-Link discontinued support for it like 5 years ago.
There are several other computers in the network and they work with the ethernet cable and wireless too, but they're all XP. So it's probably something with Windows 7.
Having stable connection to the internet is just the main goal I want here.
