 ===== Introduction =====
-When selecting the SSID to join we need to manual edit /etc/config/wireless to ensuring it uses the correct AP.
+In a situation were the AP and more than one bridge/repeaters have the same SSID we need to force the bridge/repeater to lock on to the AP. To do this we use the MAC address of the WLAN AP.
+When selecting the SSID to join we need to manually edit /etc/config/wireless to ensuring it uses the correct AP.
 first you'll need to know the BSSID of the one you want to connect to.
 if you're on 2.4ghz, at the command line type
 "iw wlan0 scan"
+===== Prerequisite =====
+The bridge/repeater routers needs to be configured correctly.
+The bridge/repeater IP address is found on the main Access point.
