The Linksys WRT610N Simultaneous Dual-N Band Wireless Router is the first true dual-band wireless router we've reviewed, and one of only a few on the market. In our tests, it easily handled 2.4Ghz and 5Ghz wireless clients simultaneously. Its 5Ghz throughput speed, though not the best we've seen, was also impressive-- though we wish its range and 2.4Ghz speed fared better. The router, when coupled with an external hard drive via its USB port, also serves as a network-attached storage (NAS) device--a great feature. If you must connect to both Draft N 2.0 worlds, then by all means, consider this router. But, if you can live with just a 2.4Ghz frequency, you will get a much better deal with the
Linksys WRT310N .
