Dual-band routers, which essentially run separate networks on the 2.4GHz and 5GHz bands, are becoming increasingly common. Networks based on the 2.4GHz band support older 802.11b/g devices, but 5GHz networks (which are compatible with 802.11a gear) are less subject to interference since they have more non-overlapping channels. This makes them a better option in densely populated areas, where 2.4GHz networks often knock each other offline.

Netgear at CES introduced a second , which doesn't offer the same performance as the N750 but has some extra features such as technology to identify the best channel for network performance, support for remote streaming of media on an attached USB drive, and a new user interface for managing the router.

, meanwhile, has introduced two 802.11n routers and an 802.11n access point/signal booster that use so-called SmartBeam technology designed to speed things up by focusing the wireless signals on clients (instead of simply broadcasting them everywhere). The D-Link DIR-645 2.4GHz, 802.11n router and the D-Link DIR-845 dual-band (2.4GHz/5GHz) routers also have USB ports and support for streaming media from connected USB drives. The D-Link DAP-1525 access point can also be used as an Ethernet bridge connecting any networkable device with an Ethernet port to a Wi-Fi network.

More Network Cameras for Remote Monitoring

Another networking trend: The profileration of networked cameras that you can control remotely to monitor homes and/or offices.
