I've had similar WiFi problems with an old MBP that seem to correlate to heat. I think the built in WiFi card may be going bad and as it get's hotter, it goes on the blink.

Same kind of showing connected by not transferring data, at other times it report no WiFi card installed. I put a laptop fan under it and the problem went away.

I expect, if I keep the MBP, I'll eventually need to replace the WiFi card.
