WiFi lossing connection - reconnecting

Idriel
WiFi is losing connection few times per day. 

It comes back after one minute (it reconnects) but why does laptop lost connection in first place?

All I have in log that every 10 minutes there is WPA rekeying.

    What version of UTM?  I have had serious issues with WiFi since 9.307-6.

    I'm also using firmware version 9.307-6 and logging handshake events that seem to be related to client connectivity loss. On inspection of the event on a Windows host, the network driver reports corruption and requires a reboot to reconnect. Linux clients who lose connectivity can no longer see the broadcast SSID which also requires a reboot to resolve. I saw in previous release errata that a custom MTU might be required. Has anyone else tried this?

    Hi, jgoddard, and welcome to the User BB!

    What MTU do you have?  You might want to try the links in GuyFawkes' post. (I found that by googling site:astaro.org wireless flash ap)

    It doesn't sound like you need this workaround.

    Cheers - Bob
