BBB wireless wifi disconnects after ~20 -30 mins

[an...@osmobot.com]

Hi All, 

I am not sure if anyone else has faced this issue. I have BBB Wireless installed with latest Debian installed in it. Wifi works fine for less than an hour and disconnects. I use Dynamic IP. Can you suggest me some solution for my problem?
