I've done that. I'll offer up a 3rd choice which I have been using. Horst. Runs on OpenWrt perfectly and free. I've not tried it on CeroWrt yet but I don't see why it would not work. http://br1.einfach.org/tech/horst/ With horst I've verified that the 3 AP's we are running are all on 5Ghz channels that don't have another AP on them. We are up on the 10th floor of a tower type building and 3 of our walls have large windows with clear views of surrounding buildings. We are higher than most of the stuff around us. So when I scan I do see a lot of intermittent probes or wifi traffic from other things but nothing cronic. I haven't been able to run a scan when it all goes to hell though. With horst it shows me the DATA or QDATA packet among the radiotap info and that the contents are encrypted but I've not figured out how to capture decrypted traffic at the same time as radiotap info. This would let me see exactly what sort of dynamic was happening from our network. As an aside if any of the gurus here are near the Boston, MA area and want to do small business Wi-Fi consulting let me know. We will gladly pay someone to fix our wireless. -- Richard A. Smith
