The TP-LINK TL-WN422G Wireless USB Adapter gives you the flexibility to install the PC or notebook PC in the most convenient location available, without the cost of running network cables.

With powerful 4dBi detachable antenna, the TL-WN422G remains excellent performance in the long range and bad environment, it can receive signal from wireless base even separated by 2 floors. The USB adapter can be plugged to the laptop directly or put on the table, convenient and portable to carry, it´ s a right choice if you need a pocket USB adapter.

Its auto-sensing capability allows high packet transfer up to 54Mbps for maximum throughput, or dynamic range shifting to lower speeds due to distance or operating limitations in an environment with a lot of electromagnetic interference. It can also interoperate with all the 11Mbps wireless (802.11b) products. Your wireless communications are protected by up to 256-bit encryption, so your data stays secure.
