After I followed these steps, I haven't had any dropouts. I just thought I'd share this in case anyone else has the same issue.You're right about those symptoms being power management related. The 8192cu kernel module has power management enabled by default:
I was able to disable power management completely by creating /etc/modprobe.d/8192cu.conf with the following contents:Code: Select all
pi@raspberrypi ~ $ cat /sys/module/8192cu/parameters/rtw_power_mgnt 1
After creating the file, you will need to reboot. You can confirm that power management is disabled after rebooting by verifying that the value of the rtw_power_mgnt parameter is now 0.Code: Select all
# Disable power saving options 8192cu rtw_power_mgnt=0
Code: Select all
pi@raspberrypi ~ $ cat /sys/module/8192cu/parameters/rtw_power_mgnt
