I'm a total n00b when it comes to Raspberry Pi; I bought one yesterday and installed Raspbmc.
Everything is working quite well except for wifi. It's an old dongle using the Ralink 2571 chipset. I got it to an almost working state, but I'm missing the final step.
The dongle sees the networks immediately. I changed the settings through NetworkManager to use a static IP. I then ssh through the wired IP, and turn off the power saving mode (
iw wlan0 set power_save off), unplug the wired network, and I get a pretty stable connection through wifi.
However, I haven't been able to make this change permanent. I've put
wireless-power off in
/etc/network/interfaces but it does nothing. I've changed
/usr/lib/pm-utils/power.d/wireless to always set pm to "off", but it also does nothing. Then there's
settings.xml for the NetworkManager add on, but I don't see any option to set power management there.
Short of putting some in a startup script, what can I do? For the startup script option, what would be the correct startup script?
Thanks in advance!
