I recently purchased two Aironet 1252 (Dual 2.4Ghz & 5Ghz radios). And a weird *bug?* has been discovered. I can bridge (root to non-root method) the 2.4GHz radio's and use the 5Ghz radio as Access Points, but can not bridge the 5Ghz and use the 2.4 as APs.
In this latter configuration the Non-Root radio, even though its enabled, refuses to turn on (stays as the red arrow). Anyone come across this before.
