REGRESSION: (compared to previous public release: Yes, No, ?): yes

DESCRIPTION:

So i’ve been using wifi hotspot for Teams meetings pretty much daily since pandemic started. Teams is on android device, while i share the internet from my X10 with sfos.
Previously (i think around 3.4) there was a regression, that whenever the phone reconnects to different 4g antenna, the internet sharing stops working and i get disconnected from the meeting for bried amount of time. It was annoying, and also led not being able to be in the meeting during driving. But it was manageble during walking, and i mostly walk during these meetings.
But now wifi sharing became absolutely unstable =\ it just randomly stops working during calls (meaning android device is loosing wifi connection) and it happens very often. I’m constantly getting dropped from meetings and this is now a problem for me =(

Restarting network somewaht helps for some minutes, but then it usually starts dropping again.

PRECONDITIONS:

STEPS TO REPRODUCE:

  1. share wifi with wifi hotspot in SFOS
  2. connect to wifi from Android device
  3. start a video call from some messenger (Teams, Telegram)

EXPECTED RESULT:

  1. stable call connection

ACTUAL RESULT:

  1. wifi from android phone getting disconnected randomly

ADDITIONAL INFORMATION:

Restarting network somewaht helps for some minutes, but then it usually starts dropping again.

Does it happen when SFOS device (the one sharing the internet) is being charged with the screen on?

nope, i’m outside the house mostly during this.

I wasn’t suggesting you to move inside)) I was wondering if this is a suspend issue or is it something else. With the screen turned on, the system should never get suspended. Network packets are being shuffled around by the CPU, and if CPU falls asleep, you may experience communication delays long enough for the video stream to break.

if it were going to sleep, it would probably not work at all? Not sure if cpu is needed for wifi sharing anyway… And why would it sometimes start breaking like constantly and sometimes it can go fine for 10-20 mins
