I have 4s. After I updated ios7.0.3 my wifi is geyed out. I expected after ios7.0.4 update wifi will work again, but does not. It annoying, because I have to use my data... Does anyone know when it will be fixed or does anyone have the same problem?

i had the same issue - iphone 4s updated to ios7.0.4. wi-fi worked for a couple of days and then became greyed out.

i followed the apple instructions to deal with it http://support.apple.com/kb/TS1559 and i continued to have the greyed wi-fi.

i took it to the genius bar today where they ran an hardware diagnostic test and i was told it wasn't the software but a wi-fi issue and they replaced my two month old phone on the spot. maybe you should follow their suggestions and if that doesn't work book into the genius bar.

I

exactly what i will be doing 3 DAYS after my last replacement for the same issue.Pathetic Apple

I have the same problem. After the upgrade, my wifi is greyed out, and the battery won't hold a charge long. I reset all the settings, tried all the things suggested by Apple, but it didn't work. I took the phone to Verizon, but they said they can't fix it, go to Apple

I made an appointment at the Genius bar, where the staff was incredibly rude and dismissive. A representative told me that the wi-fi is broken and I would need to buy a new phone for $200, because mine is out of warranty. I'm due for an upgrade in a few months, so I'm not going to pay $200 for another 4S now. I'm also not going to buy any more Apple products. Their upgrade caused this problem, and they are not standing behind their producet.
