I have the original droid RAZR (am eligible for an upgrade with VZ but waiting for HTC one...or do you recommend Samsung S4?). Anyway, in the meantime, I've had problems with my wifi. Low or bad connection, going in and out, not connecting automatically despite that being my chosen option. Stupid Comcast upgraded my router which comes wifi default. I disabled that bc it was interfering. and I have deleted other networks, tho I shouldn't have to if it was working correctly. and that's only a temporary fix. I have read some online mentioning a 'wifi fix' app. Anybody have a recommendation? Thanks!
