I reflashed my 770 with

SU-18_2006SE_3.2006.49-2_PR_F5_MR0_ARM

in windows and my I'm getting the same error that the op is getting?

it was working perfectly before but a couple days ago before the flash it came up with the network connections error although it would connect to my network.

I have added a thinkpad t43 to my network since and that is the only change.
