Hello everyone,
i'm running Kubuntu 16.04 as a Virtualbox VM host, and a wireless AP

My WLAN connections frequently keep dying, so that i need to disconnect

My syslog is full of these:

Also added to wireless-info.txt for better legibility.
I'm not sure if this is the right forum to post this.
If it isn't, a pointer to the right place would be appreciated.
Please include me in the reply as i'm not on the list.
Let me know, what additional details i need to provide, as i'm
interested in getting this to work.
Thanks.
Regards
Mario
