I am having issues connecting a 2nd 7921G to my uc520 demo kit. i am able to connect the 1st 7921 no problem and when i copy the WLAN setup from the first phone (SSID/security) settings to the 2nd 7921G, the 2nd one wont connect. it wont even recognize a wireless signal. has anyone experienced this problem or do i just have a bad phone and i need to call TAC? thanks!
