wifi not working

This is real simple guys. If you have Comcast, you have to call them and tell them it is your iphone. Iphones and comcast are not compatible it seems. They have to reset your modem. Have your pc up and running when you call so they can walk you through it. I just went through it with them. you can reset your phone until the cows come home and it won't do any good.

does your wifi already enable after turning off and on the airplane mode?
