It really does smack of the old Archer C7 V1 Broadcom issues. A firmware fix was coming for months and months and months, eventually after more than a year or so of empty firmware promises they agreed to RMA for a V2 model. I had always purchased TP Link products up until then but after that I got Netgear and then ASUS as my main routers (the C7 V2 went straight into a press in it's wrapper and is still there many years later lol). I foolishly purchased these S4's for additional mesh cover around the house, they are just access points feeding from my main ASUS so I was thinking what's the worst that could happen. It's just frustrating and has served to remind me to never buy TP Link ever again. Not worth it. I know of no other company that literally churns out routers and different variants of those routers all wholly incompatible with each other. Shocking stuff. There probably won't ever be a production firmware update for these variants and eventually people will move on and they may RMA the handful of M4 & S4 units left out in the wild when it's less costly for them to do that. I'll be very happy to be proved wrong but......

That would be great indeed since there are sometime really weird behavior when it tries to select the AP; happen very often that devices (not only 1!) will select the weakest signal when it has one box into the same room ... Having this option in a stable version to at least hint what you know the preferred one to select would be a basis when the automatic process it completely nuts.

  @David-TP Hey, how can I revert back to stable firmware from the beta please? 

And if I do, can I then go back on to the Beta without causing problems? Just need to test something, getting a lot of latency online suddenly.
