Comment (by pozega.tomislav@…):
i was using RT3070 usb wifi adapter on my MR13U for a long time without
issues until there was a need to move router further away from directional
antenna.
5m long usb cable that works with my laptop could not init the adapter
when connected to the router. so i bought 1.8m y-usb cable and with only
main connector the problem persisted but when plugged another into second
(power only) usb port i was able to use adapter.
since ports should give 0.5A and 2A output this was unacceptable that i
get so little power and can't connect any cable longer than 2m.
i was trying BB latest revision because of some driver tweaks and found
out i'll have to try it with CC to be able to test everything i intended
(ath9k_htc)
while testing this adapter (WN722N) with CC i was surprised that my RT3070
adapter also works with only one usb connector attached to router, because
it never could work this way in AA or BB.
then i flashed back BB image and to my surprise it continued to work with
only main usb connector, until there was a heavy thunderstorm and in the
middle of testing thunderstruck hit somewhere near maybe a mile or two, my
RT3070 adapter reset and usually it would come up after reboot but this
time that didn't happen.
the router was running at the battery at that time, i already tried to
disconnect main board from battery for a minute, flash image again,
restore config but nothing helps i am getting these for all 3 of my ralink
adapters and one realtek 8187 adapter

what to do to reset CPU or whatever is needed so this thing can function
normally?
the only adapter that is recognized without problem after this storm shit
is WN722N and it works properly so i would guess the hardware was not
damaged but rather something internal like some sort of
controller/register/whatever you call it?
