Are you in the market for a wireless router or a network switch? First, let’s look at what you are really buying. A modern appliance that is marketed as a Wireless Router is typically 3 devices in 1 package.

Router – A device that connects 2 or more networks.
Wireless Access Point – connects wireless devices to a wired network
Network Switch – connects wired devices together on a network

For home and small office, here are some of the wireless routers people recommend. Typically I link to products I use, but for my personal and business use I use the discontinued Cisco Small Business Pro model AP541n.
Here are some features you might want to look for in a wireless router for home or small office.

Easy setup – You can just turn it on and connect one cable end to your broadband.

They are very easy to switch to access point mode for small office installations.
