[Note that this repo does not reflect how I code Python now, maybe I'll rewrite this as an adept Pythonista some day ;)]

forced_roaming package provides a mechanism to switch between APs when an alternative AP is better than the AP the device is currently connected.

Use it as "python3 -m forced_roaming -w WLIF". You can read help with "python3 -m forced_roaming --help".

It first records the strength of currently connected AP. Then it does a scan and records the strengths of the APs with the same SSID as the connected AP. Finally, if the strength of current AP is bad and there exists a better alternative, it disconnects from the current AP. (And hopefully the wireless manager of the system will connect to the better alternative.)

It can be run from a script or a cron job to periodically scan latest status.

Current state of the package is quite basic and it is based on some strong assumptions. The device must be connected to an AP when the package is run. All the alternative APs must have the same SSID as the AP the device is currently connected to. There should be a program managing the wireless networks (like NetworkManager), it must try to connect to the best AP when current AP is disconnected and it must be able to associate with alternative APs.

Features I'd like to add:

• Using NetworkManager (via nmcli interface) to force association with chosen AP.
• Listening to 'iw event' and running the loop inside the Python code and responding to wireless events immediately.
• We should be able to give a list of APs to use instead of looking for APs with the same SSID as the currently connected one.
