Cisco’s new router doesn’t include an ADSL modem, but it can connect to an external one and is ready for use with Virgin’s cable internet service. It promises speeds of up to 450Mb/s, but as with all claims of wireless speed, this is purely theoretical. Its six antennas mean that it can use 3×3 MIMO (multiple-input and multiple-output) technology to boost range and signal strength, although to benefit from this, you’ll need an adapter at the other end that supports the same speeds.
Sadly, the only adaptor capable of handling 450Mb/s speeds is Intel’s Centrino Ultimate-N 6300 chipset, and we didn’t have a suitably-equipped laptop available for testing. Speed tests using our Centrino 2-equipped laptop and Cisco’s own WUSB600N adaptor (£27) were impressive, though. On the 2.4GHz band, Cisco’s adaptor did better, reaching 62Mbit/s at close range. At 5GHz, we reached a colossal 81Mbit/s at close range with both adaptors, and 37Mbit/s at long range with Cisco’s adaptor.
With its dumbed-down software and arcane web interface, the E4200 offers little else but speed. With such limited availability of the Intel 6300 wireless chipset in laptops, there’s currently no point in investing in the E4200, especially at this launch price.
