My phone updated to jelly bean on tuesday morning, and i noticed i cannot connect to my home wifi. It will connect at school or work however. I have tried turning off and on my phone and my router. I know its not my connection because my other devices all connect to it. When i go to the wifi on my phone, it detects my home wifi with a full signal, but when i put the password in to connect, it says the signal is poor and it just repeatedly tries to connect. Is there any way that i can get my wifi to work again? If i have to and if there is a way i will uninstall jelly bean if thats the only way to get it to work again.
