I think it depends on what you need. I would think a Belkin, Netgear or a Linksys router will suit you well. It is all up to you but it is best to purchase a router which has wireless and wired capabilities. It is best to look for a MIMO router too. As for wireless capabilities, please ensure that the router is capable of 802.11 a/b/g. If best, get one which supports 'n' too although it might be quite expensive.
