Just a followup - I was at the A67 club when I posted this but I had issues in the main WC earlier. I was in the main club when around 11AM I lost my connectivity. After that point I could get a signal but couldn't get an IP address. They told me it was over-loaded. So I grabbed lunch and went down to the club near A67 and got the same thing. Signal quality was sort of medium there but I got connected - just couldn't get an IP address again. Several people around me were having the same issue. They tried resetting the router a few times to no avail so I ended up paying the $8 to get on the airport's net to do my work.
