I have troubles with some routers (enterprise cisco in my case, tho
others like linksys work fine so far).
In my case, I find the interface gets disconnected. Retrying may
succeed - or may fail - if it fails - i reload the driver and it starts
working again - i am using iwlwifi (intel N 6300 (rev 35)). Disabling
and re-enabling wireless via KDE plasmoid is the simplest fix.
I too see many messages like above:
