So, once the first scan triggers the beaconing, everything should keep 
working ok ?
Or should I throw together a small script that triggers a scan once 
every 10minutes until this bug is fixed ?
(In my case the mesh nodes should stay online 24/7 without user interaction)

I have a semi production setup with about 10 mesh nodes, in a building 
where multihop is required due to the extensive use of metal plating and 
therefore 'poor' wireless performance. In a typical scenario I need 
about 4 to 5 hops to reach the nodes at the other end of the building.

The nodes only have a single antenna connected, so I need to change some 
code to disable antenna switching, but I'm not a C expert/module 
developer at all so that might take a while to figure out...
I thought I managed to do it about 2 months ago but broke something 
since the nodes seemed to work perfectly after updating the wireless 
modules but they all went offline 3 to 5 days later and only came back 
online after reverting to the stable 2.6.29 wireless modules.

Anyway, when I get that issue worked out without breaking anything else 
I'll see how the multihop performs and report back in a few days.

Thanks!
