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.
