Ubuntu 18.04 4.15.0-23-generic slow down #90

Hi, I upgraded to the last ubuntu (18.04) and the adapter got really slow (80Mb/s before to 10Mb/s after) Do you know if there's something to upgrade about this here ?

daedroza commented 6 years ago

I can confirm. Is there a way around this? I can provide logs or something to help around here. (TP-Link WN822N)

I was able to solve this problem by blacklisting the rtl8xx2 module & forcing 8192eu module to start at boot. Really thanks & grateful for this driver @CGarces

@daedroza could you provide instructions on how to do that ? it would really help !

Install RTL8192EU Driver

git clone https://github.com/Mange/rtl8192eu-linux-driver; cd rtl8192eu-linux-driver; sudo dkms add .; sudo dkms install rtl8192eu/1.0;

Blacklist RTL8XXXU Driver

echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf;

Resolve Idle PM issues (Check issue #94)

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf;

Force RTL8192EU Driver to be active at boot

echo -e "8192eu\n\nloop" | sudo tee /etc/modules;

Update changes

sudo update-grub; sudo update-initramfs -u;

Reboot

systemctl reboot -i;

I was initially frustrated that WN822N Router was shitty on my Linux Mint. I ended up fixing TP-Link provided driver until I found this Mange's RTL8912EU driver which has full support for Linux/Windows compilation. After installing this driver, I'm kind of happy with the performance.

I hope this resolves your problem.

@daedroza I followed your instructions and indeed it's now back to normal speeds. Thank you!
