[EDIT, Solved]
The EW-7811UTC only supports 5GHz band 1 and 2, according to Edimax support. That translates to lower channel/freq. It works for me now, though not yet able to report on stability or speed.

And now? Have you been able to test?

I'd be very interested in knowing that as well! Have you managed to establish a stable 5 GHz connection with the EW-7811UTC?

I setup my 5ghz settings on my router (TPLINK WD9980) to the settings shown a couple posts back and my Edimax 781UAC connects flawlessly and reliably over 5g network using LibreELEC 7.0.1 and RPI3.
