I've had similar issues with clients (Blink camera sync modules) connecting to far-away APs instead of the much closer router. I could not force them to connect directly to the router no matter what.
Turns out the 2.4 GHz radio of my router had died (Fritzbox 7590, apparently a common issue), thus forcing 2.4 GHz-only clients to use those other APs.
In ubiquity gear you can “lock” devices to a specific endpoint. I suspect ultimately you would prefer to have failover available but at least for troubleshooting you can see how it connects to that specific AP. Similarly you could see the amount of clients connected to an AP on every frequency and WiFi version.
You can ban devices from all access points except one. That is not "locking" it to one, it's just preventing it from successfully connecting.
It will still try to roam, it will still cause issues.
A lot of the roaming logic is in the clients. Newer android and iOS versions have gotten better but there are tons of old and new devices with poor roaming logic and capabilities.
And actually debugging this unless you have a bunch of enterprise level kit, or know exactly what the failure you’re looking for is is absolutely impossible
I used Wireless Diagnostics.app on macOS ("Scan" window) and looked for the 2.4 GHz radio's MAC address which was nowhere to be found. But yeah, you have to have a hunch.
Thanks - I’ll try this. I have a problem where my kindle only downloads books in one room (but I can make purchases in any), and I’m pretty sure that it’s connecting to a different AP and doing something stupid in the process
To be fair a few months later in 2002 I got to see a second cousin playing gta 3 on pc. That really sent my 11 year old brain spinning.
not even finally buying my own home with my wife this year gave me the such a thrill, perhaps because it was very grueling and we still are waiting for some repairs to move in.
