Degraded Network Performance Under Fedora 17

I have a Dell XPS laptop which worked fine under Fedora 16. I recently
upgraded to Fedora 17 and the wireless network performance has
degraded significantly. It seems to work well when first started up,
but once I've transferred a reasonable amount of data, the throughput
drops to a trickle until it finally dies out completely. I can usually
start another good patch by turning the wireless off and on again.

I know little about networking drivers under Linux so I'm not sure
what information will be helpful to track down the issue. But I'm
happy to run whatever commands you think will be useful and report the
results.

As a start, here's my Smolt profile.
