Q: iPad 2 upgrade version 5.1, now no wifi

Does the ipad even see the desired network? 

Same problem - The hospital used to hire out dongles - now ceased - thus I don't think that is your iPads' fault - get back home and wifi will work. Get well soonest

Additional things to try.

Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

I have the same issue.  I did the latest iOS update and now no wifi at the house on ipad.  Had no issues before the update.  2 iphones and an 2 ipods plus 2 windows laptops all connect to the internet over same wifi no issues.  So I know it is not the router or network.  What gives? I can see the network and it acts like it is connecting but does not. 

1. Have you tried rebooting router?

2. Reset network settings: Settings>General>Reset>Reset Network Settings

3. Have you tried changing the security settings on router e.g. WEP, WPA, WPA2

Yes, I rebooted router.  All other devices still connected...no ipad

Yes, reset network settings on ipad. I even went as far as backing up ipad and restoring it.  Still no connection.

Yes, It was set to WPA2 then I went to no security and the ipad saw it but it did not connect. 

Trying to figure out if there is a way to go back to previous version.  Not a happy camper right now.

I even don't upgrade to the new OS but my WIFI is also GONE !  So I think it has nothing to do with the new OS but with the ipad 2 wifi...!@#$%^&*()_+

Pls help

I have tried all but still the same

Unable to Connect After iOS Update - saw this solution on another post.

I upgraded my OS to 5.1.1 the day it first came out.

Now, weeks later, right as I'm playing a multiplayer game online, my wifi dies.

The iPad tries to scan for nearby networks, but doesn't pick up a single one...

The 'Choose a Network' is endlessly searching for a network.

I've turned wifi on/off.

Reset All Network Settings.

Reset and Erased all Content.

I'm lost.

The wifi antanea must have burnt out because it has been working flawlessly up to this point with the newest OS.

I also have the same problem.  All other devices connect to my wifi with no problem. IPad 2 suddenly cannot connect to the wifi. Would rather not restore the ipad to factory settings, if possible. Anyone having any luck fixing the problem???

Just got back from Apple Store. They verified it is a hardware issue and not software related.

I now have a 'remanufactured' iPad 2, which to me means refurbished.

Bummer, but at least I have connectivity again.

I'm def going to purchase the apple care warranty because my 1 year warranty is almost up, and the repair would have cost me $249.  

Good luck.
