[RT-AC87U running 384.5] 5GHz Guest Network doesn't work

[Sween]

After being upgraded to 384.5, my RT-AC87U's 5GHz guest network no longer works. The network doesn't show up on any of my devices that are 5GHz capable; it's like it's not even there.

The 2.4GHz guest network option still works fine, but before upgrading to 384.5 I used 5GHz guest networks without a problem.

I was waiting for a new firmware release, but there hasn't been a 384.6 release for the RT-AC87U.

I don't know why 5Ghz guest network don't work, guess it has something to do with the (Quantenna)firmware for the 5Ghz in the 87u
