Service Pack 2 killed my wireless network

I have a mn 700 hooked to 1 computer and a mn730 in my
other computer remotely located. XP n both. I downloaded
SP2 to the remote computer. It now tells me all IP
addresses are zero and will not talk to anything. It was
kind enough to inform me that there was a known problem
with microsoft broadband and this operating system but
would not tell me anything else.

Found 1 reference to a mystery document "871122" that does
not really seem to exist. Found one bit of instruction to
run ncpa.cpl and manually load the IP addresses which I
did with no effect.

Any help would be greatly appreciated.
