Honestly, if anything the problem has gotten worse. I mentioned in my first post that by rebooting the device I was able to get connected for at least a little while but that doesn't even work anymore. I simply cannot connect at all. Again, according to my router's log authentication is successful everytime. But the N900 is not happy for some reason and keeps trying to reconnect.

Is there a cache or something I can clear out? I have occasionally had similar problems on my laptop (running Debian) which I would solve by deleting some files in /var/run and restarting wpa_supplicant however I do not how to do the equivalent here (I do have rootsh installed).
