Description：
The TL-WN821N Wireless N USB Adapter complies with IEEE 802.11n, IEEE 802.11g, and IEEE 802.11b standards. Wireless
transmission rates can reach up to 300Mbps. The USB adapter with internal Omni-directional antennas works well with
other 11g and 11n protocol wireless products and adopts MIMO technology which can bring a faster, wider, and more
stable wireless experience. This product can also simultaneously operate bandwidth intensive applications using a lot of
bandwidth which are sensitive to interruption. When using multiple bandwidth intensive applications, the most sensitive
of these applications can be given priority over the others to be allocated more bandwidth in order to assure quality.
