@David-TP I tried setting the connection preference but that option wasn't available for my laptop. Interestingly enough, it was available for my Pixel 8 phone and my wife's iPad and iPhone, but not my LG Gram laptop, our housemate's iPhone or any of our Sonos equipment.

THe firmware version is 1.2.0 Build 20250718 Rel. 43949 for all 3 of our Deco units.

  @David-TP - creating the IoT network and giving it only 2.4GHz while removing 2.4GHz from my regular and guest networks worked, thank you for that. However, while that was a smart workaround and your help was really appreciated, the BE65 still wasn't working as it should. I hope your team keeps that in mind as they continue development.

As an FYI, I had already updated the drivers for my WIFi adapter, and now set the Preferred Band to 5GHz as you suggested.

Thanks again - R.

  @Rooster998 you're probably having similar issues to other BE65 owners with the recent 1.2.0 firmware. Just do a search on the community pages and you'll see for yourself. I also note TP Link seem to have hidden some threads on this matter. 1.2.0 has introduced critical bugs causing a huge headache some some owners.
