      Hello, I upgraded from 1.2-RC4 to 1.2.1-RC2 and my wireless setup was messed up in the process.

      The Effect
      The symptoms observed were that the ssid was no longer being broadcast, nor could any client trying to connect anyway get any response. I used kismet and saw absolutely no sign that my wireless card (a D-Link Atheros card) was alive.

      My router's dmesg said:

      The Solution or more like "fix"
      Some searching led me to this post - what I took away from it is that in the switch from FreeBSD 6.x to 7 one change with the Atheros cards is that setting them to automatically select their own channels would result in them trying to operate on channel '0' which is non-sense.

      So I then used kismet again to see what channels were in use around me and picked a channel far from the other noise. I bound my wireless nic to that and a brief moment later the dmesg issues were gone and my client machines could see my router's ssid being broadcast.

      A secondary issue/concern
      While I was troubleshooting this issue, I decided to reset my router to factory defaults. I'm not sure if doing so helped create my secondary problem or not. Once my machines could see the ssid from my AP - they could only associate with it, but not connect to anything.

      The issue was there were no forwarding rules in my routing table for the wireless interface. Hence adding those rules resulted in everything working normally again.

        Thanks for the report, we are looking into it.  If you happen to stumble across any more information, please share.

          We fixed the problem you noted a long time ago so this is obviously something different. Post the contents of your /tmp/ath0_setup.sh

            Here's the results:

              That shows you have the channel set to 9, what does it show when you set the channel to auto and then what does it show when you run it?

                Sorry, took some time to catch everyone off the wireless. Seems to me that running ifconfig while it wasn't functioning returned that it was using channel 0, but maybe I just read that. Anyway, looks okay now and seems to be working fine. Hope this is helpful.
