Thanks Marcello. Unfortunately, Apple Extreme routers do not allow for disabling the 5ghz frequency...

I had forgotten about it sorry. I was under the impression that you could disable by Alt-Clicking Radio mode in the Wireless Options window of Airport Utility but I was wrong, I double-checked and you can only have better control on the protocols.

BTW, if you need a suggestion for an alternative I switched to a Netgear R6250 as the access point in the living room and to a R7000 as my main router. The extreme (the "brick" version) became too obsolete for my needs.

Edit: By the way I can confirm that when I had the 5Ghz I had no dropouts. Either the TV would detect the speakers at power-on or it wouldn't.

I have a Beosystem 4 with a Transmitter 1 and 5 Beolab Receiver 1s. I've owned the system for 1.5 yrs. I have had numerous random dropouts (Speakers power off out then back on moments later). The situation appeared to be associated with heat. See /forum/general-discussion-and-questions/bv11-bl1819-wireless-issues#post-2057278 where another user and myself have attempted to rectify the problem. After placing feet on the Transmitter 1 and installing  two 120mm quiet fans behind the Transmitter 1 I haven't experienced any subsequent dropouts. I don't have 5GHz wifi in my home, only 2.4.

Edit: Nevermind. I quoted by mistake stuff that I thought was recent..

After updating the BL18/19/receiver1 software to the latest software version 2.0.6 ( believe)  I have had rock steady Wisa connections to my Klipsch wisa hub for 6 months.

The SQ is also immaculate :)); fully as good as a wired optical connection.

I have no issues with wifi interference, and the wisa and wifi hubs are mounted only 20 cm apart.

Here you can see WiSA transmitter in BeoVision Avant 2014.

Maybe it is possible to create a better 'antenna' if there are problems.

I have a Transmitter 1 (software version 5310 (Latest)) and 6 Receiver 1s. I do not have a 5Ghz network in my home. I still on occasion have issues with WISA. The speakers will have digital noise. It can happen on startup or even later. Its random to me. Fortunately its rare but it does happen Last month I experienced it twice after a year or so of no issues. I use the system daily.
