We have Intermec 751 mobile handhelds and three WLAN controllers. A 4404-100, 4402-25, and a 2000-6. The 4404 & 2000 series are running 3.x WLC code and the 4402-25 is running 4.x.
We're using the same SSID & WPA-PSK on all three controllers, and the handheld associates with the controllers that have the 3.x code, but not the WLC with 4.x code. Besides the different code, we have the exact same WLAN's defined. We've also tried creating an Open WLAN with no security, and still nothing. We're using the Intermec Settings app to manage the WLAN settings..
Has anyone run into this before? Other devices - laptops and CK30 scanners can connect, but not the 751's. We're going to open up a TAC as well, but I thought I'd check the boards to see if anyone else has encountered anything similar.
