Internet speed slow on Ubuntu 18.04.1 with TP-LINK TL-WN821N
Solution 1:
I have the exact same problem as your and I solved it by doing this:
- Install
rtl8192eudriver from here:
https://github.com/clnhub/rtl8192eu-linux (I used this one)
or here:
https://github.com/Mange/rtl8192eu-linux-driver
- Add
blacklist rtl8xxxuin/etc/modprobe.d/blacklist.conf - Reboot.
