If you have a mix of B, G and N devices (as most of us do), your best bet is to go with a simultaneous dual-band router like the $169 D-Link DIR-825 Xtreme N Dual Band Gigabit. This model excels at automatically connecting devices to the appropriate band, without user intervention. There are other dual-band routers that are good choices as well, like the $119 Linksys by Cisco Dual Band Wireless N Gigabit Router. This model requires user to be savvy enough to know how to configure settings so that all devices (be they B, G or N) can connect to the correct 2.4-GHz or 5-GHz band.
