If your wifi seems more like why?Fi? on your Raspberry Pi with RaLink adapter...

I've been banging my head against this one: My v2 home grown home automation system is running on a few Raspberry Pi A+, and some of them are running the RaLink R... wifi USB units.

Networking seemed flaky. From the Raspberry Pi, everything works as it should, but incoming requests are frequently dropped or terribly slow as described here.

The solution for me seems to be to turn off the power saving feature of the USB wifi dongle, and I managed to do it with the advice from here:

Add the following line below the wpa_conf line in the /etc/network/interfaces file:
wireless-power off

For the moment, I think my problems have disappeared like mist before the sun :)
