No ways... it's not working.
It's months I can't use Wi Fi, I tried every possibile way found on this forum or Google, but still not working.
I feel it's very crucial that a device like iPhone 4s hasn't a working Wi Fi connection.
I think this is not a real bug or mistake but something planned in Apples policy: it's is not possibile that they can't fix a problem like this.
Before I have another post removed I urge all those affected with wifi issues to exercise your rights as I have done as published on apples vet own website.
There are far too many of us affected for this to be a coincidence or consumer caused problem, I had a 16gb white 4s purchased in July 2013 and wifi was completely greyed out no matter what fixes I was advised to try.
I have been successful in my claim and am now in receipt of a brand new iPhone 5, this was provided to me by the phone shop I signed my O2 contract with last year.
Good luck and persevere
Hello guys, I'm comming back with a negative feedback regarding the iOS WIFI problem, i bouggt this iPhone4 since it got out on the market with iOS 5.1.1 and worked perfectly the iOS got out with great futures and of course I upgrade it and the problems started, I've tried so many solutions but none of them seem to work with my home router, after the update diden't want to connect to my home router but the rest anywhere I could connect easly. This year iOS7 got out and of course I got it (the biggest mistake), since the update the iPhone4 is much much slower and the WIFI problem is still here! The iPhone sees any network but it can't connect to most of them, I diden't had the time to see an Apple Genius but by the time I had this problem the iPhone was out of the waranty. I solved my home WIFI problem by adding an AccesPoint to my network working with WIFI separatly (another name) but getting the DHCP from the router. It works fine, but I'm a big fan of Apple and will solve my problem in other ways then suing Apple (you will lose if you do so), changing router setting or adding anothe WIFI (acces point) to the network. I'm sorry to see that a brand big as Apple don't read these post and listen to people from time to time! Peace!
