I have a Buffalo wireless router and it appears to work fine, for the most part. However, printing out some debug information, I noticed that the Mode is reported as unknown/bug.
In the DD-WRT configuration, I have selected AP which should be Master. I was having a problem earlier with my ESSID being a bunch of weird characters. I re-entered it and restarted the router and now the ESSID is correct.
I tried re-entering the configuration for the router and it still is reported back as Unknown/bug via iwlist wlan0 scanning.
