Sometimes it takes too long for the network manager to update to see new wireless AP. Is it possible to change the time interval between checks?
The "refresh rate" (scan interval) is hardcoded in the source code of network manager. The interval is some value between 20 and 120 seconds. Some heuristics decide when to scan more often and when less often. There seems to be no way to configure the interval other than patching the source and compiling.
See the relevant source file of network manager version 0.9.0 and search for interval.
There is a lot of discussion in the internet about allowing users to change the interval. The developers do not want that. They argue that users might set the interval too low causing grievance, not only for the user, but for all members of the wireless network.
So it seems that it is not possible to configure the refresh rates, and it seems that it will not happen anytime soon.
You can trigger a scan manually using the following command:
You can list the found networks using
You can observe the activity of your wireless device using
