The TP-Link WN881ND is a wireless network adapter compatible with standard PCI Express slots. It operates in the 2.4 GHz band and is compatible with IEEE 802.11 b/g/n standards. It utilizes dual polarization (2x2 MIMO / dual-chain), with a maximum theoretical throughput of 300 Mbps. The device is equipped with two external omnidirectional antennas with a 2 dBi gain. The antennas are detachable (RP-SMA connectors), allowing for the use of other products with higher gain if necessary.

Stable Wi-Fi connections guarantee uninterrupted entertainment
The TL-WN881ND PCI Express wireless network adapter allows you to connect your computer to a wireless network, providing high-speed internet access. With wireless transmission speeds of up to 300 Mbps, you can play games without interference and watch HD video streams smoothly.
Antennas that adapt to your needs
The TL-WN881ND network adapter features two detachable antennas whose direction can be fully adjusted to suit your environmental conditions. To further extend your network range, these can be replaced with directional antennas or other high-gain alternatives.
