iPhone 4S on iOS 6 wifi problems!?!?

Try resetting your network settings under general and reset in the settings app. This worked for me hope it works for you!

I just updated, too. I have an iPod Touch, but this might help: When you go to your setting and click on wifi, select the network, click "forget", then switch your wifi from on to off, restart, then switch it back on after everything is restarted. I did all of those seperately, but once I did them together, it worked. Hopefully it will work!

Settings > General > Reset > Reset Network Settings

Switch your phone off and back on again the reconnect your wifi through the settings. That has just worked for me :)

Turn on airplane mode. Try connecting to your wifi again as usual. Should work fine. The deactivate airplane mode. Worked for me anyway

Before you do anything drastic, reset your network settings. I was experiencing the same problem but this fixed it.

Go to settings > general > reset > network settings

Cheers

I'm sure Apple will fix it soon, everyone is having the same problem

All iPhones had same problem but they seem to be working now

My brother figured out. Turn off Siri and then turn back on

This is a known bug. I can only hope that it will be fixed quickly
