Slow RTL8188FTV in Debian/Ubuntu

Since the RTL8188FTV usb WiFi chipset is natively supported by Ubuntu/Debian, I got few for my Ubunut machinies.  The WiFi dongle is indeed detected and works straight away, however it is very slow.

A quick search on Google shows this may be caused by its aggressive power management.  After applying the below to disable its power management feature, its connection/speed is noticeable better.


sudo mkdir -p /etc/modprobe.d/

echo "options rtl8188fu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/rtl8188fu.conf
