TRENDnet 4-Port Broadband Router TW100-S4W1CA
Though lacking any noteworthy bells and whistles, this is an excellent choice for a simple home or small business network. It has a single dedicated WAN connection and four 10/100Mbps half/full duplex LAN ports. This pick isn't ideal if you want to connect five or more computers together, but otherwise it's a great choice as the firewall and network management tools included by TRENDnet are powerful and easy to use, so you don't need a lot of networking experience to effectively set up this router. These tools include features like virtual server and DMZ support, along with web URL filtering and a firewall. This is a great option if you need to set up multiple small networks on individual routers because you can get this model at a very reasonable price, even if you need more than one.
