Replied by pauledd on topic Raspberry image download duration?

Just an side note to those who use a wifistick with kernel module 8192cu and encounter massive ping fluctuations in RPi direction.
Symptom:
cat /sys/module/8192cu/parameters/rtw_power_mgnt
1

Ping from RPi: (looks okay)
Ping to RPi: (is a mess!)
Solution for me:
load the kernel module 8192cu with this options:

/etc/modprobe.d/8192cu.conf
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
and reboot.

Effects:
cat /sys/module/8192cu/parameters/rtw_power_mgnt
0
Ping to RPi: (looks okay now)
I also get now much better responsiveness through ssh. Maybe this was also the source for the disconnects I've got with usbip, but I cant test right now.
