AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual
LAN
The router is preconfigured to automatically provide IP addresses to all the computers in the Local Area
Network (LAN). Your router allows you to create and configure LAN groups.
LAN Configuration
Your router’s default IP address and subnet mask are 192.168.1.1 and 255.255.255.0, respectively. This
subnet mask allows the router to support 254 users. If you want to support more users, you need to edit the
subnet mask but remember that the DHCP server is defaulted to only give out 254 IP addresses. If you
change your gateways’ IP address and you have DHCP enabled, the DHCP configuration must reside within
the same subnet. The default gateway is the routing device used to forward all traffic that is not addressed
to a station within the local subnet. Your ISP will provide you with the default gateway Address.
