I had Windows 7 beta working great on my Intel Core2Duo motherboard (DG965RY). Then I installed the Windows 7 RC. Now it will not connect to the internet through my router. The strange thing is that it will connect properly to the other systems on the network but not to the web. I tried reinstalling the chipset, management engine and LAN drivers with no success, even using Vista SP1 compatibility mode and running as administrator (all drivers are latest for Vista x64). The management engine does seem to install OK, but the others don't. The message is that it's the wrong version of Windows. I could understand the issue if it also didn't work with the beta, but what changed with the RC to cause this? Anyone else with similar problems?
