Folks,
I had posted about this back in April when 0.3 came out and hadn't seen
it happen since the 0.4 releases until today. I have a WRAP running
0.4.1, all upgrades. One Engenius NL2611 as 2.4GHz AP and one CM9
backhaul on channel 52. Seems it's a random thing as to which radio
gets wifi0 and which gets wifi1. Obviously having the wrong order on
boot takes the system out of service since the configuration parameters
are totally different for the two radios. I had one suggestion
regarding adding some udev rules to match MAC addresses and assign
interface names to radios discreetly but I would prefer to simply know
which mini-PCI slot was going to get 0 and which gets 1 and have it stay
that way. Has anyone else experienced this? Is this a direct result of
udev? What's the best approach to remove the uncertainty in device
discovery?
Thanks,
Edwin
