I had a problem with a huge initial time period when the AP simply seemed to be ignoring one of the assigned channels. That turned out to be because the channel was in the DFS range and even though there’s obviously nothing round here that will be detected, it seems the device waits for ever for an initial all-clear, which is I suppose understandable. But it makes it unusable on those frequencies, so I stuck with the lower ones once I found out what the problem was. I wish I could just disable DFS and that’s and end to it, but I’m sure that ZyXEL would be worried about getting into trouble. One fix might be geolocation and access to a map with a whitelist/blacklist but then that all gets incredibly expensive and complicated and the WAP would have to download the map from the internet, or else query some server, which implies having internet access. And would have to have internal geolocation hardware too. Might be worth it to really fix the problem though as an added high-end feature.
