I could just turn off the wireless on the HH5, nothing ever connects to it. It just sits there and bleats its SSID to an uncaring audience. It's the support act for the wifi upstairs and everyone is in the bar. I seem to have reasonable wifi now, it just didn't fix the Sonos problem. Which might not be a Sonos problem, it could AirPlay, robotic squirrels, or the fact that I have a Hell portal under the hallway floor. The myriad complexities of modern life are hard to fathom. It may be interference. I should also turn off the bloody BTwifi-x and the other crud it puts out. You have no friends, BT HH5, accept it. The Arlo hub on the other hand, puts out a fearsome signal. That punches through to the garage at the bottom of the garden. I'm not sure what Chromecast is doing, but it has its own network too. Then the neighbours, EE-that, BT-that, TalkTalk, Sky, and the randomly appearing PrettyFlyForAWifi. There's frankly a lot more SSIDs than I have neighbours. The Sonos is on channel 1 which everyone seems to hate. I should also unbury the speaker in my wife's office as she buried up under a menagerie soft toys and squished behind a monitor which I'm sure is electromajickally shielded.
That said, when it works it works, and I currently have Waxahatchee blasting out in my remote command centre, the dining room, and the kitchen. I think it's just scared to go upstairs.
