For an university research project, we need to be able to dynamically change certain wireless configurations (channel, power, adding new SSID) without restarting hostapd and resetting the existing connections. Currently, when we want to apply the changes, we have to restart the entire hostpd and this will disassociate all the associated clients. Is there a way to make potentially minor wireless configuration modifications without restarting and resetting everything? If not, then is this more a driver-related limitation or a hostapd-related limitation? Are there any ongoing efforts to achieve what I just described?
The current level of support for dynamic changes to an operating BSS is
to cover just the WPS needs. You may be able to change some other
parameters, too, through the relatively recent control interface
changes, but I'm not sure what the exact level of functionality is
available. There is ongoing work to provide channel-switch mechanism.
