Troubles with usb Wi-Fi rtl8188su

[LockeF21]

So, I have a TRENDnet TEW-646UBH wireless adapter (rtl8188su). With this adapter my internet speed very slow. I'm found many posts with problem like this, but not found a worked solution. I try to install https://github.com/pvaret/rtl8192cu-fix ... /README.md this drivers, but now pages not load at all.

I also try this, but it does not work for me also.

Code: Select all

echo "options iwlwifi 11n_disable=8" | sudo tee -a /etc/modprobe.d/iwlwifi.conf

inxi -N does not show my adapter.

What I can do in this situation? Sorry for my bad english)

inxi -N

Thanks, I try this, but got "Error! There are no instances of module: rtl8192cu-fixes 1.10 located in the DKMS tree."

I solve this problem by installing proprietary 8192cu driver.

But now I return to my first problem - internet by wi-fi is very slowly.

lhsw -c net
