Cant connect to any wifi with my d-link dwa-131

Hi, im joao, a new linux user. I happens that i cant connect to any wifi network. When i try so, i says that the wifi network could not be found. I have no ideia of what to do. I already tried adding


to my NetworkManager.conf (it wasnt there before) and rebooting my pc, but it still dont work.

Thanks in advice

Since i have no internet on manjaro, i cant copy-paste the results of the commands. Also, if you can find a solution to that, what commands should i use?
