Aimesh AC68U only 5Ghz?

[grr]

I have the following configuration:

1st floor: AC68U, aimesh master
3rd floor: AC66U_B1, aimesh node, wired
Garage: AC68U, aimesh node, wired

Everything works well with one exception, the router in the garage only lights up the 5Ghz led, and even when standing right beside it, a phone connected to 2.4Ghz gets only one bar signal, which makes me think it connects to one of the other routers, and that 2.4Ghz is actually not running on the garage router.

Anyone seen this before?

Try a power cycle. If it doesn't fix it, try a factory default reset.

If it still fails, then there's a good chance the 2.4 GHz radio of that router is defective.
