Make sure you know what 802.11n performance you’re buying. All 802.11n Wi-Fi products below are 802.11n, but as you can see, performance varies significantly. More antennas and streams mean faster speeds, less dead zones, fewer dropped connections, and better coverage. 802.11n multiband support effectively creates more room for data by bonding two 20MHz channels into a 40MHz channel. The 5GHz band best supports channel bonding.
