Nothing works still. Quick recap:
WIndows 7 Home 64bit
LAN not working;
Unidentified Network - Work network
Only WIndows 7, Office 2010, NVidia drivers
for GTX260 programs (no adobe or Apple - bonjour...)
imputing my Billion router IP address over 169.XXX address and gateway....;
reset and renew ipconfig;
disabling LAN and reenabling;
disabling IPv6 (lost network there, didn't see it);
reinstalling from Intel generic drivers the LAN drivers;
deleting 0.0.0.0 (didn't find it);
tried killing starting the modem;
can't access modem through the IP address (but the modem, via the laptop, can see the LAN cable of the PC);
tried resetting the IPv4 and 6 via resets;
no firewalls or AV;
tried via safemode.
Only thing now is to try and reinstall WIndows 7.
If not change the Mobo.
