[Voyage-linux] Loss of AP function with Wistron DCMA-82 radio - v0.6

[Edwin Whitelaw]

Very weird problem here now occurring on two different systems both with 
fresh and updated loads of Voyage 0.6

A note, I've used the DCMA-82 w/o problems as 5GHz backhauls but these 
two installations are the first as 2.4GHz APs

System A - ALIX with two DCMA-82 radios, one as 5GHz backhaul, the other 
as normal AP.  System comes up and runs well, good throughput and power 
but will spontaneously lose all client connections typically within 12 
hours.  Dropping the interface (ifdown ath0:0, ifdown ath0) and bringing 
it back up restores function.

System B - WRAP with one DCMA-82 set for bridging also v0.6

-----------------------

This was installed two days ago and has lost AP function three times.  
Due to bridging, I reboot the board to restore function previously but 
this morning even that is not working.

I'm going to try an XR2 this morning to see if there's a difference.

Anyone else seen this or used this radio as 2.4 AP successfully?

Thanks,

Edwin
