Connect Multiple Networks: WLAN routers are also ideal for wireless networks in public areas, especially if there are multiple networks that are accessible.

Instead of having one box for the router and another box for the access point, a WLAN router provides both in the same box. As a result, you need a router if you plan to have more than one networked devices on a local network sharing a single ISP-assigned address. NAT then maps a particular client on the local network to the ISP-assigned IP address whenever that client needs to access the Internet. For example, you can subscribe to a cable modem service that provides a single IP address through DHCP to the router, and the router then provides IP addresses via DHCP to clients on your local network.

IP Address Sharing: WLAN routers offer strong benefits in the home and small office setting.

These functions make the WLAN router much more versatile than an access point.Ĭonsider using a WLAN router for the following reasons: WLAN routers also have the ability to provide port-based control, firewall management and Dynamic Host Configuration Protocol (DHCP) services for all devices. In addition, WLAN routers implement the Network Address Translation (NAT) protocol that enables multiple network devices to share a single IP address, which are generally provided by the Internet service provider ( ISP).

The router always takes the IP address into account to make decisions on how to forward (i.e., route) the packet whereas, access points generally ignore the IP address and forward all packets. The main thing to remember is that access points allow wireless clients access to a single network, while WLAN routers allow clients to browse a number of different networks. There may be some confusion over the difference between WLAN routers and access points. 802.11g routers are also starting to hit the market. 802.11b, 802.11a, and 802.11b/a combo WLAN routers are now available from several vendors such as Netgear, D-Link and Actiontec. This gives wireless users the same ability as wired users to send and receive packets over multiple networks.

A typical WLAN router includes four Ethernet ports, an 802.11 access point, and sometimes a parallel port so it can be a print server. This combines multiple Ethernet networks with wireless connections as well. Most routers connect a local area network ( LAN), like the one in your home office or small business, to a wide area network ( WAN), like the cable system connecting a cable modem, by interfacing a broadband modem to the network within the small business or home office.Ī wireless local area network ( WLAN) router adds a built-in access point ( AP) function to a multi-port Ethernet router. Routers use Internet Protocol ( IP) packet headers and routing tables, as well as internal protocols to determine the best path for each packet. The router chooses the next best link to send packets on in order to reach closer to the final destination. By definition, a router transfers packets between networks.
