DFS is really a cool feature, it can simplify the process of choosing a channel. As the docs say:
“AP scans channel list from “scan-list” and chooses the frequency which is with the lowest amount of other networks detected.”
So, I’d like to suggest a change. I think the time ROS takes to scan for a channel is too low. If we use Freq. Usage, we can see that some channels are a little bit free and then, suddenly, gets very busy. So, why not adding a box or something so we could choose how many milliseconds ROS would keep scanning to determine the best channel?
After the choosen time, ROS could calculate an average for each channel and then, select the best. It isn’t a good idea?
So, I’d still suggest another feature, something like “Dynamic Channel Selection” or “Automatic Channel”, which would do all those steps I’ve described before.
Remember, you can’t be scanning and have clients connected a the same time. People would rather a connection that works 10% slower and stays online 100% of the time.
Besides, the channel with the least amount of other APs is not always the best channel.
I think DFS scans and selects only ONCE (when you enable the interface)
you can make use of scripting, to disable/enable interface at 3:00AM for example, to choose best frequency every night. also the DFS does something when it finds a RADAR.
It won’t work nice, because at 3 AM most of every company’s customers are sleeping, so, the “sky” will be quiet. I preffer choosing the best channel at night, 8 PM, so the whole city is using their antennas and we can see the worst situation possible.
