I'm using an Linksys WRT54G with tomato firmware for a number of years. The AP 
is in my house and very close. I will keep an eye on this. This all seemed to 
have started after we had a power outage. The AP is fine however and I haven't 
noticed this drop a 2 after.

If there was any environment changes they appear to have 'settled' down.

I will be going to 2.6.38-0.rc4.git0.1.fc15 right now and will do another long 
hour test by keeping the laptop on for a number of hours on the weekend.

Thanks,
Shawn.

To answer myself, https://bugzilla.kernel.org/show_bug.cgi?id=28832

Looks like this is behavour observed in -rc3 the same period I did the 
upgrade. I can discount the power outage :)
