I have a Toshiba Satellite C-55 and recently changed to Ubuntu 19.10, I'm completely new to Ubuntu, so there's nothing much I know what to do, except googling before asking, but I'm stuck. My internet connection got really slow like a day or so after installation, and IDK why, but I found out that is a common issue with Atheros devices, which my computer has, so I tried to enter the following command:
sudo su
echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9k.conf
As seen here: Qualcomm Atheros - Slow/Not connecting on Ubuntu, but works in Win 10 But... it got stuck there, it's doing nothing (I think, but whenever I try to close the terminal, it's saying that there's still a process running, but it has been like that for an hour, what do I do?
