If you are looking to upgrade your router, the Quadband DIR-855 and its adapter from D-Link should be worth a look when it hits the shelves in May.
It’s designed to boost speed, range and performance of a wireless network when running multiple devices including high-definition media players and it can support concurrent 802.11n transmission over both 2.4GHz and 5GHz channels at the same time. The latter is less crowded, making it ideal for streaming more weighty HD. The DIR-855 is optimised to work with the DWA-160 Wireless N USB adapter, with its selectable dualband (2.4GHz or 5GHz) wireless signals and both products are backward compatible, able to be used in existing 802.11g and 802.11a networks.
Other features include five Ethernet Gigabit ports, Dual Active Firewalls for security, three dual external antennae for best coverage and an OLED network activity display. Expect it in May for £169.99.
