There have been recent post with people having problems with their wifi not being stable.. Stuck in a connect disconnect loop?.. I have a few tips you can use if you are having these problems. First change your encryption from AES to TKIP.. also make sure DLNA is not running on your phone.. this can cause the phone to see one network as two and try to change from one to the other. If your phone is rooted you want to make sure your not having a problem with the kernel you are useing.. if you think you are having this problem you can try to flash a new ROM.. also a simple restart by removing the battery can solve many problems you may be having.
