Invalid Misc?

Postby alexnetdoc » Thu Nov 30, 2017 10:45 am

Hi,

recently I have installed Linux Mint on Y520 Lenovo laptop. I had to unblock the wifi card and install the drivers in otder for the connection not to drop. For now the wifi is stable 50/50 of the times. it can be stable for all day, but then drop again. Sometimes the connection drops only for web????? confused... All other Linux machines are working, windows devices are working and phones are connected. I am newbie to Linux, so maybe someone knows what is Invalid Misc means and how properly to check wifi error logs?

Any help would be apprecated
