I have a similar problem with my wrt54g (stock firmware) which doesn't play nicely with the power saving on the Freerunner's WiFi chipset. Try disabling the power saving mode using Freerunner. I don't remember if i need the iwconfig command, the wmiconfig command, or both, to make the connection reliable, but both are mentioned in the wiki. If you use a roaming wpa_supplicant configuration in /etc/network/interfaces you can probably put the required commands in pre-up and post-down to automate its use on the access points that need it, but not those that don't. http://wiki.openmoko.org/wiki/Wifi#Disable_power_management > The problem itself is as follows: > > I connect to the AP from my freerunner, no matter what client I'm > using, I've tried several.
