rtl8192cu 0bda:818b Realtek Semiconductor Co error Ubuntu 18.10. [Logs+system's info]
Hello guys, the current situation with my workstation goes as follows: The only way to access the internet is via tethering and the wifi adapter does not seem to be recognized by the networking system. I will enlist the command lines I've used in the past as a result of my previous research alongside my system's info. Please, be patient and I really appreciate your help.
