Some questions about the Network Manager

Post by lordjusto » Sun Feb 18, 2018 8:23 am

Hi community,

I have installed the latest x86_64 Cinnamon version of Linux Mint. And I've found a behaviour with the Network-Manager that also happens while using Wicd. When I start the computer (using a Wi-Fi USB, TL-WN823N), the connection can't be established in any way I know. But it can be established (automatically) after I reinsert the USB Wi-Fi adapter to the USB port. Does anyone knows why does this happens? And how it could be change so I don't have to take out and put in again the Wi-Fi adapter?

Notice below the first attempt after startup that can't connect, and the second one that does after I unplug and plug back the USB Wi-Fi adapter:

Code: Select all
