i am using the latest mt76 update 22.03-SNAPSHOT

I don't touch the phone for a while, it goes into idle mode, but when I touch the device again, the connection doesn't reestablish itself again

Is this an iDevice? If yes, is autojoin turned on? Probably yes, but just to make sure. What are the steps you need to perform to re-establish the connection?

viniribeirossa commented 2 years ago

Yes. I turned off the device's wifi and turned it back on.

@kocoman1 can you post your wireless config. We have seen similar issues with the mt7615d with DBDC mode where radio0 is a 2.4 AP and the radio1 is a 5 GHz station connection. In our case the station is connected to a 5GHz DFS channel.

thelinuxdude commented 1 year ago

In our situation we have a 5GHz STA connection to an AP that switches to DFS, when this happens the AP on the other radio in this case is a 2.4 AP will drop all clients and will not work until restart the radio using wifi up radio0 which is the radio being used for the 2.4 AP. We see similar issues after a site survey where the AP starts to act up and drop packets. Heard there are some TX race condition and stability that needs clean up and was not sure if this is related to that issue.
