I have a Macbook Pro 13" running 10.6 that I purchased at the beginning of September. For a few weeks now, I have been getting random wifi disconnects.
The strange thing is that they only occur when the minute is :00, :10, :20, :30, :40, or :50. More often every 10 minutes, less often every 60 minutes. I am using a Linksys WRT54GL router with HyperWRT + Thibor firmware. This problem did not occur when I first got the Mac.
Yesterday I decided to format and reinstall Snow Leopard to try to resolve some issues I was having. I installed, then used Migration Utility to restore my files and settings from a Time Machine backup. I am still getting wireless drops. I tried deleting AirPort configuration plists as described in county's post here but to no avail.
When I check my router config after a disconnect (I usually reconnect within 15 seconds, but sometimes I have to turn AirPort back on), the DHCP lease remaining time is 24 hours from the disconnect time.
Additionally, after deleting the plists did not work, I looked at them and discovered the following:
com.apple.airport.preferences.plist:
That time minus 7 hours is the exact time of my last disconnect. That entry is in the dict KnownNetworks, under my network SSID.
It may be a DHCP problem. I will try using a static IP, but having a static IP means I'll have to change my network settings when I go to school and when I come home.
This occurs in both 10.6 and 10.6.1 with my current settings.
Any suggestions would be appreciated.
Edit: still occurs with DHCP with Manual Address and static IP.
