Impact to Production Wifi network when RF settings

[Charlie Grey]

any experts can advise what is the impact when making changes to the followings?

- Change WLC RF leader for 5Ghz RF domain.

- change the Channel bandwith for 5Ghz from 20mhz to 40mhz.

is the impact transparent in seconds or there will be impact and wifi offline for few minutes?

thanks for reading.

You can't change the Channel Width without turning off the 5.0 Ghz and then turning it back on.

This is one good example why it's better to use CLI than the GUI.  

With GUI there will be, at least, 4 seconds of outage to the 5.0 Ghz.  With CLI, however, the outage time will be about <1 second.

what about changing the RF leader btw 2 WLC in the same RF domain?

will the outage be just a few seconds?

anyone?

Never tried that so I can't say.
