Gene,

Out of curiosity, did you check ipv6 settings?  You might have only ipv4 network, and ipv6 settings are enabled by default?

I had such a case and I was cursing the new kernels, I wanted to write bug reports and do a bunch of things, I went to the Administrator of the network and blamed it on him, because wired connections would work and this one would not , I checked the settings again and again, several times over, saw the ipv6 check and removed it and solved the problem by myself :) I hope a solution like this is possible for you, if not, I still tried and shared my story.

Regards,

Antonio
