My iphone 4 running 4.3.3 will connect on my work sonicwall tz100w router, but my iPad2 running 4.3.3 will not. Settings are exactly the same using DHCP for both ipad2 and iphone4. I have no problems connecting the ipad2 to my home uverse router. I can see the network and it will ask for key, but it will say cannot connect. I also tried just to use open security to see if it was a security problem and it did the same thing. Any clues?
