TC21 - poor ability to roam between ApPs

Got quite a few TC21's that are dropping WiFi connection, and immediately reconnecting back.

Mostly happens when in use, where the user is moving around a warehouse. After a lot of digging through WiFi logs, it appears that the TC21 is very reluctant to switch to an AP that is closer and provides a much better signal.

The WiFi infrastructure is Cisco WLC controlled, and no other clients are having any issues, also the warehouse have been site-surveyed recently.
Only 5GHz radios are enabled.

Is there any settings on the TC21 that can be modified, to make the scanner more willing til shift AP???

I'm not aware of any specific settings on the device that could improve AP switching.

I would recommend raising a support ticket if this is impacting your operations so we can determine if we have a bug, or if this is expected behaviour. Also make sure you're on the latest OS & LG patches as we regularly push bug fixes when they're identified.

Alternatively, perhaps you could configure the APs to drop connections for the TC21's that are below a specific db which would force them to reconnect to the stronger AP?

I was considering that, but had to drop the idea. I believe the feature you are referring to is known as "Rx SoP", however it is similar
to using a hammer, since it will affect every client on the Wifi infrastructure - not just the TC21's. Being android v. 10. I'm sure there are tons of possible settings - just need to know what they are, and how to change them..

There is a "avoid poor connections" setting in android under the WiFi settings, which may help improve performance.

Alternatively, there is a 3rd party app on Play that seems to let you configure thresholds & preffered networks, which may be worth testing.

Sounds interesting. Where in WiFi settings is the 'avoid poor connections' located?? Will have a look at WiFi switcher as well..
