N66 in wireless repeater mode, doesn't find any 5ghz.

[pkbristol]

I have an RT-N66 in wireless repeater mode, AC68 is main router.
On the N66, when i do a scan it only finds my AC68 2.4ghz and all my neighbours 2.4ghz, it doesn't find any 5ghz from my AC68, or my neighbours, i know there's at least one from neighbours.
Is this correct ? The N66 can only find 2.4ghz ?
When i use wifi analyzer on my android, that can see a 5ghz coming from both routers, on the 2.4ghz the N66 mirrors the channel on the AC68, but the 5GHZ from the N66 doesn't mirror the channel from the AC68.
I have Merlins 380.62 on both routers.

Thanks, Paul.

I seem to have found the solution, on the N66 i had to manually type in the 5ghz network name being broadcast from the AC68, i couldn't find it with a scan.
Can anyone shed any light ?

Thanks, Paul.
