Wifi network problems after upgrade to android 10

Hi, a few hours ago I did get and run the android 10 rollout.
I do have weird network issues and I wonder how to determine its cause.
Every few minutes my FP seems to be unable to connect to the internet anymore … while the wifi symbol still shows wifi connection. The only workaround seems to be to disconnect and reconnect to the wifi network. There are other devices in the same network without that issue.
Otherwise it will switch to mobile data and reconnect to wifi itself

This is not very handy … it also causes my mobile data amount to shrink fast… whenever I don’t notice that I actually run on mobile data and do some data usage … like a download or watching a video…

I didn’t determine yet if it is a similar problem when running in mobile data only … it also is wayyy harder to trace a network change then … because thats stuff which are automated processes by mobile service providers. I would need to lock to a special local antenna manually … and I even doubt it would be easy to get locked on a special network slot.

Are there others with such issues?


Hi Michael,

which router model do you use in your wi-fi, and what channel does it currently use? I did not notice any changes in wi-fi behavior with my FP3 so far.

Best wishes,


Hi there,
I seem to have the same issue.

Before the update to Android 10 everything was fine with my wifi.
But since then I experience exactly the same as you described…

I currently have no solution.
I use a Telekom Speedport Smart 3
With one 2,4 GHz and one 5Ghz network (separate)

I’d like to backup above scenario. Since the upgrade to Android 10 on FP3 I am suffering from instable Wi-Fi connection. More often than not FP3 is using my 4G. Other devices in our household do not have that problem and FP3 did not have it with Android 9 neither.

  • Running Android 10 8901.3.A.0045.20200905.
  • Rebooting FP3 does not do the trick.
  • Same behavior for 2.4GHz as for 5GHz

Would love to see advise on solving this issue.

I can confirm this, since the update to Android 10 I also experience regular interruptions of the internet connection with the Fairphone 3. The WLAN however remains connected. The router used is also a Speedport Smart 3.

You might want to try setting the 5 GHz network to a lower channel manually. Instructions can be found on p. 211 of the SpeedPort Smart 3 Handbuch

Good luck,


Same problem here, seems to getting worse. First restart helps but now it disconnect sometimes after 10-20 seconds.

For me, this has solved the issue. I changed the set WIFI channel from channels 100, 104, 108, 112 to the lower channels 36. 40, 44, 48. Since then there was no more instabilities in wifi conncetion.
Do you have an idea what the cause of this issue is?

I bought an FP3+ recently and this is the first major issue I’ve noticed.

Changing my radios to indoor channels is not a solution for me. How can I help get this diagnosed and resolved?

Hi Thomas,

router model is same as of Josh-Au. A Telekom Speedport Smart3.
It is capable of some “smart” wifi functions … it was described to me as a kind of “focus” of the wifi send/receive power to connected devices instead of unfocused broadcast.
Sinced it becomes harder and harder to get some verbose information from apps and devices i can’t tell what kind of technologies it uses. Shiny black boxes in white shiny shells.

I feel sorry for my late reply … I wasn’t online at the one computer where I logged in … and I didn’t have my account data stored somewhere else.

I wonder if there are some tricks to get more informations from my running android. Some tracking of current network connections and stuff.

Maybe I am too old for all those new and shiny and silent stuff… it happens wayyy too often that an app or device just is doing whatever it is doing … and all the things I might want to have an eye on or customize or make an alternate decision just happen “somehow” and “somewhere”. Example: when I download something … it becomes more and more common that it just is stored “somewhere” in the fog or maybe at my device … i sometimes just can guess or hope or pray. (i prefer to say fog, not cloud)

Hi Michael,

kind of absurd to write in English when this is obviously about a Deutsche Telekom router, but anyway: it would definitely make sense to bring up your issues over at the Telekom hilft Community. A quick search


shows that you are not alone. Let us hope that somebody over there has already found a solution or at least a workaround.

Finger crossed,

Maybe this is a different issue, but I’ve used multiple radios from multiple vendors (Ruckus, Cisco, Zyxel) and am still seeing this issue.

My home personally uses a Ruckus T300 AP. It appears to be fine with all my other devices, as well as my other two Android 10 phones, and I’m assuming my two housemates Android 10 phones.

Today I will run a ping test to my gateway with the screen left on and compare results across different channel ranges.

Well it doesn’t hurt to write in English, as we are all struggling with in essence the same problem. That FP3 since the recent upgrade to Android 10 looses it’s Wi-Fi. :slight_smile:

I have done as suggested earlier and changed the Wi-Fi channel to anything below 100. Now the STB is unhappy, as it is using 5GHz, too.

I hope FP will soon release an update …

About the same problem here, since last systemupdate yesterday (update 5 Oct.) (not since upgrade Android 10, although?) Sometimes, after reset router and restart FP3, for a little while (up to app. 1-2 minute at the most) wifi-connection. I wouldn’t blame the router but the systemupdate! Please do something about that! In the meantime back to factorysettings? Very annoying!


I have a very similar problem, not sure if it is exactly the same as described above:

My Fairphone 3+, just have it since some weeks, always disconnects from wifi for 2 or 3 seconds, then reconnects immidiately. This happens around two times per hour.
For some use cases this is not a big deal. But for me this is a huge problem:

  • Disconnect and reconnect from Chromecast all the time.
  • Interrupting SSH-connections and downloads.
  • Streaming music is interuppted.
    And much more.

Some details: I am using 2.4-GHz networks only. It happens with bluetooth turned off or on. It happens in different networks / with different routers.
Phone was shipped with Android 10 and it happens in all versions / updates since then.

I have contacted the support, but it seems like they have to deal with a lot of bug reports recently and had no time yet the answer.

But if somebody has an idea to fix it: Would be very appreciated, as this bug is driving me mad and makes the phone impossible to use (except regular phone calls).
