Does iOS 7 fix the 4S Wifi problem?

The Wi-Fi antenna in your 4S is most likely failing. My 4S on 6.1.2 connects to Wi-Fi just fine.

 

Have you tried a restore? My iPad was having similar issues a while back and a restore fixed them.

 

No clue, sorry. My 4S before the one I currently have had it's Wi-Fi fail 2 days after I got it. The one I have now is perfect.

 

I have a 4S and have had no issues whatsoever in wifi. I just recently upgraded my Router to the new Airport Extreme with 802.11 AC in anticipation for the next/newest iPhone to have that wifi capability, but regardless, i have had 0 issues with wifi on my 4S.

 

As with the other posters, no wifi issues with my 4S at all, in any version of iOS. It's currently on 6.1.3.

 

You could. But you may have to pay if you device is outside the warranty period.

 

C,mon guys! What's the point of posting if you DON'T have the problem.
This wifi problem is well reported on this and other forums including the apple forum. My personal experience is:
1. Wifi working perfectly with ios4
2. update to iOS 6
3. Wifi sensitivity very low and wont see the SSID unless very close to the AP.
4. Subsequent iOS 6.xx version updates have not fixed it.

The question remains :
Does iOS7 fix the wifi issue caused by ios6.?
Please if you don't have a problem and/or answer, what's the point of posting?
I'm personally not updating unless the issue is fixed!
Waiting until the Ubuntu Edge is released.

 

Had a wifi issue on my original 4S, got it switched last fall and my new one never drops.

If it's not working on 6.0, you mine as we'll upgrade and see if 7.0 fixes it, you have nothing to lose.
