Agree with OP
Ever since the last string of the updates from google play -adobe air, etc. and others, my wifi has not been working as well.... yes I have rebooted my phone, I have recycled my wifi connection, I have turned on then off to 3g 4g, and it still not working... I know my router works because my computers in the house are wireless and they are all connected. I have even managed to get my phone to forget my wifi settings, have a turn back on, and have the wifi go blue, but then it goes gray again and I lose connection... something from the last update definitely screwed up my wifi... guessing that it is 1 of the softwares or apps that I have installed as everybody isn't blowing up there Forums with issues, I do not have a special root installed and have a bare setup... So I will uninstall until I find it.. If I do find the app that is responsible, I will write back and report the app here....
