Q: Is your iOS6 wifi ok? What router are you using?

I had a net gear wireless n router that was great. My router now is an apple airport(sounds apple koolaidish), but it works great. I have 2 phones, 2 xboxs, 2 iPads, a pc, and MacBook all connected to it wonderfully. Streaming a video and playing a video game with zero lag has been great.

Have you tried the proxy troubleshoot and/ or the encryption?

If yours is old, I'd get a new one. Routers do have a shelf life. Especially if yours isn't a wireless N router, I'd go for a new one. Technology advances and you got to keep up I guess :)

I have not updated my iPad, but my iPhone 5 works just fine with my Apple Time Capsule.

I have updated my iPad3 to iOS6, and it continues to work smoothly with an Apple Airport Express as router.

Additional things to try.

Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

Change the channel on your wireless router (Auto or Channel 6 is best). 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.

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.

At home, I'm using an Airport Extreme which is working quite well. But to be honest, I have yet to encounter the first WiFi hot spot I could not connect to and use without problem, inlcuding when I was out of the country.

Only 2 years.... You shouldn't have problems. Go to the apple appointment. Last thing I'd suggest is update your routers firmware. Or see if there is one.

Net gear is www.routerlogin.net (from a connected computer). Popup- Default name is Admin and password is password. That was with mine anyways. Check the manual or search online for the router type.

Linksys E4200 V1. No problems after going to iOS 6. Had to reset the iPad 3 as usual and power down and up the router. I also updated the E4200 with the latest firmware. I am using Apple's recommended router settings documented in Texas Mac Man's post.

Buffalo WZR-600DHP is great.
