I have two wireless routers and when walking between them using my laptop it will not change from one wireless network to the other. It is expected that the wireless will automatically change to the stronger network without having to manually do it. There is a priority option but that is only based on a number, the user should be allowed to set the priority of the network based on it's strength.
This is a behavior that would have to be implemented in NetworkManager itself; we can't do it ourselves, sorry.
