Q: My iphone 4s will not scan for wifi, wont connect to wifi, or even recognize a network.

I have a home wifi network, and I have not been able to acsess it for a while now.  It's becoming an increasing issue, as I was able to use it perfectly about a month ago.  Everything else in my house can connect, but not my iphone.  I have reset the router, my network settings, all of my settings, and still nothing.  If i try to enter my wifi manually, my phone comes up with an error reading "cannot scan for wireless networks".  ive tried everything! Please, any suggestions will help.  Thanks!

iPhone 4S, iOS 5.1.1

    I have had this issue of not scanning for WiFi networks as well. I just tried the following, and it has worked for me, at least for the last 12 hours or so:

     

    1. Turn ON Airplane Mode

    2. Power off the phone normally: Hold power and home keys for 6 sec, then swipe the "power off" slider.

    3. Waited 1 minute

    4. Turn on phone, wait for it to reboot itself

    5. Turn OFF airplane mode,

     

    Immediately, all WiFi networks popped up, and I could select my home network with the same saved password etc.

     

    Of course, this might not work for every case, but it's easier than a phone restore and worth a try. If this works, please consider marking this as "solved"!
