My ipod touch 3rd gen did the same thing. I updared it yesterday then the wifi option was gray and said "no wifi" I looked it up and it said: Update (I had just done that) then reset network settings, then restore in itunes... I did all of that nothing changed. So I tried turning it off and restarting it nothing. I spent 12 hours yesterday looking up things to do, nothing changed.

UPDATE: I did get it to work yesterday and it has held. My problems were twofold: super-fast draining battery and the inability to connect to wifi (which was draining the battery, I'm 99% sure).
I had tried all the wifi and cell data On/Off.. . syncing. . .airplane mode On/Off . . <but had resisited a settings restore > ... .and I had dug around here and in google for any advice (finding nothing definitive).
Then I finally did a phone OFF and then ON. And I turned off cellular data (under General -- > Network
And that worked. Wifi is holding and battery is great again.
I have read some earlier posts where this solution did not hold for others. But as I said, 28 hours in and counting, all is back to normal for me and my iPhone 4 running 5.1.1.
Anyway, I'll reply to this again if anything changes.

I feel the same way. I believe that people are not noticing the fact that we also are having issues with Bluetooth. Oh, and my phone won't even backup, I erased all of my backups, beliving there was some corrupt something or other casuing all this. Now my phone refuses to backup, so no restore options for me but to wipe whole phone with icloud.

Same here, Iphone 4, poor wifi reception and poor bluetooth also, battery not lasting, because phone is always looking for a signal, therefore using more power.
All since update to 5.1.1
No roll back option supported by apple.
None of the "fixes" suggested above have worked for any prolonged time.

Guys, i've had the same issues as all of you. i recommend one thing and one thing only. Take your sim out, a couple of minutes of air, and put it back it. this might work, it worked for me. hope this helps.

I've tried every suggested fix on here and not a single one has worked. I even took the sim card out twice. I have restored, reset every possible reset, wiped it completely and started over from scratch, powered on and off multiple times with airplane mode and cellular data on/off in different configurations. Not a single thing has worked. My wifi doesn't work in any capacity. It doesn't see networks and it doesn't have the ability to scan for wireless networks. Apple needs to fix this and stop ignoring the issue.

i have the exact same issue. my wifi and bluetooth were working fine until i did the upgrade. since then, the wifi is greyed out and says "no wifi" and my bluetooth doesnt work at all. my battery isnt even lasting half a day now as well when it used to last me until i went to bed at night.
i have reset the network settings and also restored my iphone. still didnt fix it. i havent dropped my phone and it hasnt come in contact with water (i saw posts saying that it was due to water damage).
i have booked in at my local apple store to see if they can fix it. if they tell me they cant, **** will go down!!!!
will keep you posted on what they say.

iPhone 3GS updated to 5.1.1 when it was released. Wi-Fi worked fine until mid-morning today. Now does not see any networks anywhere.
Tried all software troubleshooting steps including factory resets and restores. Wi-Fi turns on and off but fails to see any networks or join manually even before restoring data.

I'm having a similar problem. Since I got my 4S about 3 weeks ago, whenever I browse the internet in my bedroom using my house wifi, the connection will randomly drop and I'd then switch to 3G. I would then have to exit safari for it to reconnect or sometimes I'd have to manually go to settings to fix it. I've tried restart it, resetting network connection, turning it on/off but they all haven't seem to fix it.
I had an iPhone 4 with iOS 5.0.1 previously and it would pick up the wifi signal fine from my bedroom and would never drop it. After reading everyone's comment, would it be safe to assume that the reason why my iPhone 4S is dropping wifi is because of the iOS installed (5.1.1 on the iPhone 4S/ 5.0.1 on the iPhone 4) rather than my 4S being faulty?

To find out if it is your software or not you would want to try to connect to some free networks such as starbucks or mcdonalds if you can connect elsewhere then you will know its not your software and that you need to check your network router at home, other then that you can just try resetting network and all settings and then try toggling airplane mode

My iPhone 4S usually works fine everywhere else. It doesn't drop wifi if I'm in the living room where the router is, but it only begins to drop the connection once I'm near the back of my house (i.e. where all the bedrooms/bathrooms are) I'm not entirely sure if its the router's fault but shouldn't be the problem as my old iPhone 4, laptops (both PC and Mac alike) can still consistently pick up and hold onto the wifi signal from the back of the house.
