Wireless disconnects every 30 minutes
Solution 1:
I think I know what this might be, as I have been egtting the exact same thing on my new Netbook and it has been driving me crazy. Every 30 minutes, regular as clockwork.
Are you using WPA-PSK ? I am. On my Zyxel router there is a setting "ReAuthentication Timer (In Seconds) " and this defaults to 1800 ( 30 minutes ). Sure enough, if I change this to 60 seconds, the problem now occurs every minute. Set it to 120 and it occurs every 2 minutes.
Check your router to see if you have this setting.
