I seem to be having problems with client disconnects related to channelfly. I have various generations of machines that drop the connection and then take several minutes to re-associate afterwards. I wanted to test with channelfly off but it seems that the 5G radio on 9.8 stays on channel 52 for all AP if channelfly is disabled. I think this is due to background scanning being disabled with this combination.
In 9.7 and maybe first release of 9.8 (I can't remember) there was a setting to disable channelfly after 30 minutes I thought. I can't find this setting any longer though? I am running 18.104.22.168. On my network channelfly never seems to really settle down, I have 100+ channel changes in 15 minutes with only 12 AP.
Is there any difference with these issues / settings with 9.9?
Yes, background scanning is disabled in 22.214.171.124.15, but R700 customers can
enable ChannelFly for a period of hours or couple days, and then disable it again
to let your APs find a better channel, after building internal interference to channel
databases. Its this db updating that results in frequent channel changing at first,
but should settle down on better choice channels, since ChannelFly looks at more
than other SSIDs, but also RF interference from non-802.11 sources. You can
specify how long to run Channelfly and disable after X minutes, under the Access
Point Group configuration in 126.96.36.199.15. I'm doing some testing overnight to
confirm 188.8.131.52.205 behavior.
