I got AT&T U-Verse set up. Everything's fine except that my Macbook Pro and my daughter's Macbook Pro lose wireless connection every 15 minutes or so. When that happens, I can't ping to the router (192.168.1.254). I have to turn AirPort off and turn it on, then it starts to work again. But connection is lost again later.
So far, my Windows 7 laptop seems ok.
After some research, I changed the following things but no luck.
- I disabled 'Wi-Fi Protected Setup' in the router.
- I changed the wireless channel to 9 from auto.
- I set DNS to outer server not the router
- I turned off IPv6 on my Macbook Pro.
Has anybody experienced this problem?
