SVC3 not allowing me to join wireless network

[genealle 0]

Two wireless SVC3 cams were working fine.

Got a new dual-band router from ATT with the fiber install.

First cam responded well with SVC3 client and I joined the new SSID with no problem

2nd cam seems fine with SVC3 client except it always fails to connect to the same SSID.
I tried choosing the SSID from the list and tried manual entry.
Cam connects fine with LAN cable, just not WiFi

Both are set to the 2.4Ghz band and I tried the 5Ghz band

Any clues?
