Wifi network problems after upgrade to android 10

It seems that the Phone disconnects (and afterwards reconnects) after successful roaming from 2.4 GHz to 5 GHz and vice versa.

That’s just one possible reason for the reconnects. In my case, I only use 2.4 GHz networks. No roaming between 2.4 GHz and 5 GHz or between different access points. There are just reconnects even when having 100% signal - other devices on the same network have a stable connection all the time.

@heini_huber

As a workaround set wifi frequency band to use only 2.4 GHz at fp3’s preferences of the affected network, this makes wifi stable again but results in speed loss.

Not all people can do that because they are affected by the “wifi band switcher becomes invisible”-bug. Same do I. So there is no chance to switch or disable wifi bands

Let’s all hope for the release of the new OS version!

My solution at the moment: Turn on Airplane mode for some seconds, turn off, Internet “work” again for a while

Sorry for quoting myself: New update (v0077) did not solve the issue for me.

I must say, I have not noticed this issue any more since the update. Might be simply because I missed the instances where it actually did happen. Would be nice if there were a pre-defined, consistent test we could run on our phones to determine if the problem is there or not. Ideas?

The simple test I am doing:
Establishing a SSH-connection out of Termux from FP3+ to a local server. There is a simple Bash-script running, printing the time every minute. So it is easy to see when the wifi disconnects.
Have been running this on several Android phones. All of them keep the connection, just the FP3+ is disconneting from time to time (usually multiple times per hour).
I reported this to the support with details and screenshots.

But there is no need to do tests like this, as it also happens in regular use, which everyone can do:

• Streaming webradios
• Controlling audio players via DLNA/UPnP
• Doing video calls
• Watching Youtube via Chromecast, controlled by FP3+

In all these use cases I still have the short interruptions of wifi (disconneting and reconnecting again after some seconds).

I use WiFiman from Ubiquiti to identify wifi issues on my phone. It enables to analyze the wifi connection and shows mac address and signal strenght of the accesspoint you are currently connected to.

Thanks for the suggestion - I have a lot of Ubiquiti equipment here but did not have this tool installed yet. Just not sure if it can run in the background and perform a connectivity stability check over a longer period?

[heini_huber]

No, checking the connection for a longer period of time isn’t possible yet. But in my case disconnects happend every time I roamed succesful between accesspoints and/or different band (2.4 GHz / 5 GHz) and vice versa - to identify such problem the app was very helpful.
