On all my eap772 V1.0 (fw: 1.0.14) access points I can't seem to select any band c channel   149, 153, 157, 161...  
I have an eap772 V2.0 (fw:1.2.0) that will let me select it .  That seems to have an AU firmware.

The v1.0 devices have an EU firmware .  All devices were purchased in Australia, so where can I download the appropriate AU firmware for the v1.0 devices?  I assume that is what the issue is?

Cheers, Marty
