RIP 1 is universally supported RIP 1 is probably adequate for most networks unless you have an unusual network setup RIP 2 carries more information Both RIP 2B and RIP 2M send the routing data in RIP 2 format e RIP 2B uses subnet broadcasting e RIP 2M uses multicasting Multicasting can reduce the load on non router machines because they do not listen to the RIP multicast address and do not receive the RIP packets However if one router uses multicasting then all routers on your network must use multicasting Note If you change the LAN IP address of the WGX102 while connected through the browser you will be disconnected You must then open a new connection to the new IP address and log in again 4 7 26 Advanced Configuration of the WGX102 202 10119 01 v1 0 Reference Manual for the 54 Mbps Wall Plugged Wireless Range Extender Kit WGBX102 Using the WGX102 in Router Mode as a DHCP server By default the WGX102 functions as a DHCP Dynamic Host Configuration Protocol server allowing it to assign IP DNS server and default gateway addresses to all computers connected to the wireless range extender s LAN The assigned default gateway address is the LAN address of the WGX102 IP addresses are assigned to the attached computers from a pool of addresses specified in this menu Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN For most applications the default
