With today's launch of the all new Trendnet Dual Band Wireless N USB Adapter (model TEW-684UB), any user who has an older system - be it laptop or PC - can now enjoy all the advantages of cutting edge 802.11n. Even customers with only slightly older systems which already have a wireless card capable of 802.11n may get a nice speed boost from this new product. We say this as this is not just another wireless N adapter, it boasts not only the older 2.4Ghz spectrum but also the 5Ghz spectrum of 802.11n. Add in MIMO support to really pump up the speed and distance abilities of your wireless network and the end result should be a nice - to significant - boost in speed.
