Laptop kicks other devices off the wlan network

Post by orlonth » Fri Jun 07, 2019 6:43 am

Hi,

The wireless on my linux mint laptop works stellar, but it seems to kick other devices off the network.
For example when I boot my laptop, my smartphone and work laptop (which is due to company policy windows 10) no longer have a stable connection. Reconnecting with these devices always results in a "connection refused". When I power off the linux laptop, the problems are gone.
Thank you for any help!

Some information on my linux laptop:
