MN-730 stops working after July Update

I have an MN-730 talking to a LinkSys WRT54G WAP, using
WEP. Well, I had it talking. Worked great. It downloaded
the July update, and notified me that it was available. I
foolishly told it to install. After the restart, no
wireless networking. I thought it perhaps had lost some of
its configuration settings, and I checked them all,
including re-entering the WEP key. No success. I have
tried backing out various pieces, and it still did not
work. I have tried manually reconfiguring everything, but
no success. Is it time to re-install everything (wireless
drivers and apps) from the beginning?

Any other suggestions?

Thanks!
