Help! Safari / Firefox won't connect to internet on WiFi?!

Question

I can't connect to internet using WiFi from Safari OR Firefox from my home WiFi (Apple WiFi router.)
Here are weird facts:
- They both work from this laptop at home using Ethernet
- They both worked at AppleStore WiFI today
- Internet at home is fine from other MacBook, iPad and 2 iPhones
AppleStore guy reset a lot of Safari and network settings, suggesting that would fix anything, but it still does not work from this laptop at home over WiFi?!
Any ideas?!
Thanks!
Mark

Answer 1

Thanks, Linc.  FYI, I don't believe I've installed any new 3rd pary items for some time (although some of them may have updated to newer versions more recently?)
I've posted output from Terminal commands below.  Let me know what you see in it!
FYI, I've been considering updating to Lion OS.  Would that a) help me with this situation, and/or b) cause me other new problems?!
Thanks,
Mark
