Hello i just bought my new wireless adaptor and is the ( TL-WN8200ND ) and i have ubuntu 17.04 in my computer i have a dual boot pc with windows 7 and ubuntu the problem is in the ubuntu the adaptor shows me all the wifi networks i click to connect it gives me the password i write the password correct im sure for that because i check for caps lock and language, it takes 10-15 secons then is giving me the message you are disconected and i know its not router fault because i have tried with other wireless routers + i open my phone hotspot and again same problem.If anyone knows something how to fix this please tell me i really need ubuntu!
Please implement the fix outlined here: Ubuntu GNOME 17.04: wi-fi not working -- mac address keeps changing?
Next, please check to see if two possibly conflicting drivers are loaded:
lsmod | grep rtl
If you find that both rtl8192cu and rtl8xxxu are loaded, then blacklist one:
sudo -i echo "blacklist rtl8192cu" >> /etc/modprobe.d/blacklist.conf exit
After making these two changes, reboot and let us hear the result.
