New NIC driver broke network connection
I have a Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20). Windows update installed a driver for a Realtek RTL8168B /8111B Family PCI-E Gigabit Ethernet NIC (NDIS 6.0 ) and then I would just get an unidentified network message for my connection. I dual-boot with Windows Vista and Vista's network connection was broken as well. After I used the roll back driver feature, everything was fixed. I had to roll back drivers in the Vista and Win 7 RC operating systems. I don't want to make the same mistake later, so I tried to hide the driver update in Windows Update, but it is still there. This is just some information for people that may be having a similar problem.

FYI - I had the same problem. W7 drivers worked, Realtek drivers did not (note: this was on Gigabyte mobo e-net chips, not an add-in card) MacAndrew

Same sort of problem - Win7 did automatic update for this network device and it stopped working. Fixed by rolling back the driver
