Hi everybody, (noob entering room) I just got the 3.21 update and it broke my wifi. I had excellent use and strength throughout my house and now it shows the strength but wont let browser, market, etc connect throught it. my tab will wifi tether to my galaxy 4g phone. I want to either go back or get a fix on my wifi. i did the tab reset, wifi reset, and forum searches please help. I wasn't rooted, but if I have to root...then fine, just want the ability to walk from corner to corner of house and use tab again. Thanks for any help.
