RE: Vista 5536 Unable To Connect To The Net

I installed Vista Ultimate last night and all seems to be working except
sound and Internet Connection... I anticipate downloading new sound drivers
once I can get onto the internet. I do have a Linksys WRT54GS Router (wired
connection) and Marvell Yukon Controller... do we still have this problem
with the full release now? Should I Disable the below flags? I was
considering getting a new router.... Thoughts?

Whatever was in the auto update last night wiped all my network settings.
Hopefully that was unintentional, or Microsoft is singlehandedly keeping
firedog and other "nerds" companies in business.

I have a Dlink draft n DIR-655 router, but I seriously doubt that was the
problem.
