I've faced a few issues after upgrading mine Acer TM 6492 laptop to Windows 8 x64:
- Frequent 1-3 seconds freezes when LAN cable is connected.
- Inability to connect to the internet via PPPOE (error 651).
I've installed latest drivers from Intel - didn't help, installed very old drivers manufacturer provided for Vista - same story.
There were no issues with same configuration running Windows 7 x64.
Cheap Moschip-based USB Ethernet adapter runs alongside just fine.
Can anyone please suggest a solution?
