AmbiCom WL250N-AR - Manual (Page 38)

Please click ‘Apply’ button to prepare to restart the router, and you’ll see this message:
Please wait for about 30 seconds, then click ‘OK!’ button. You’ll be back to router management interface again, and the router
is ready with new settings.
2-6 Wired LAN Configurations
Before all computers using wired Ethernet connection (i.e. those computers connect to this router’s LAN port 1 to 4 by Ethernet
cable) can communicate with each other and access Internet, they must have a valid IP address.
There are two ways to assign IP addresses to computers: static IP address (set the IP address for every computer manually),
and dynamic IP address (IP address of computers will be assigned by router automatically. It’s recommended for most of
computers to use dynamic IP address, it will save a lot of time on setting IP addresses for every computer, especially when
there are a lot of computers in your network; for servers and network devices which will provide services to other computer and
users that come from Internet, static IP address should be used, so other computes can locate the server.
Suggestions on IP address numbering plan:
If you have no idea on how to define an IP address plan for your network, here are some suggestions.
1. A valid IP address has 4 fields: a.b.c.d, for most of home and company users, it’s suggested to use
192.168.c.d, where c is an integer between 0 and 254, and d is an integer between 1 and 254. This router is
capable to work with up to 253 clients, so you can set ‘d’ field of IP address of router as 1 or 254 (or any
number between 1 and 254), and pick a number between 0 and 254 for field ‘c’.
2. In most cases, you should use ‘255.255.255.0’ as subnet mask, which allows up to 253 clients (this also
meets router’s capability of working with up to 253 clients).
3. For all servers and network devices which will provide services to other people (like Internet service, print
service, and file service), they should use static IP address. Give each of them a unique number between 1
and 253, and maintain a list, so everyone can locate those servers easily.
4. For computers which are not dedicated to provide specific service to others, they should use dynamic IP
address.
If you don’t really understand the descriptions listed above, don’t worry! We will provide recommended setup
values below.
Please follow the following instructions to set wired LAN parameters:
Please click ‘LAN’ menu on the left of web management interface, there are three setup groups here: ‘LAN IP’, ‘DHCP Server’,
and ‘Static DHCP Leases Table’. Here are setup instructions for each of them:
