NM fails to recognize already configured Wi-Fi connection

[joshiss]

i am using wifi network at my office. we have multiple routers at different buildings given names like rd1, rd2 etc.
they are password protetced for access and my laptop has a static ip. when i connect to any router it asks for password which is remembered.
when i move around the router is selected automatically. the routers are from CISCO mainly with model no linksys E1500.
the problem is if i am connected to rd1 and the move to rd2 router location, after some time it if i come back to rd1 location it detects rd1 as rd1 1 , asks password for router again. it coonects with automatic ipv4 setting which are not the configuration of my static settings. this causes non connectivity to network

please help how do i solve this
