The TP-Link TL-WN781ND is a Wi-Fi card that fits a PCI Express slot on a desktop motherboard. If a computer has no Wi-Fi, or its existing module picks up a weak signal and keeps dropping, this adapter fixes that — with no cable to run.

Wireless speed reaches 150 Mbit/s. That covers video, internet calls, online gaming and everyday work. A detachable antenna is included: it can be turned to aim the signal or swapped for a stronger one. A bundled utility makes choosing and managing networks easier.

Security uses WPA/WPA2 encryption, and you can join a network with one press of the WPS button — no need to type the password by hand.

  • Wireless N — up to 150 Mbps
  • PCI Express interface
  • Detachable antenna
  • WPA / WPA2 encryption
  • One-press WPS connection
  • For desktop computers

The unit works on Windows. Sold in Baku with official partner warranty.

What TP-Link TL-WN781ND is for

TP-Link TL-WN781ND is an adapter that adds Wi-Fi to a computer or laptop. It is the simplest fix for a desktop PC with no built-in Wi-Fi and for older laptops with weak reception.

Buying advice: if your router supports 5 GHz (Wi-Fi 5/6), a dual-band adapter is worth it — a 2.4 GHz-only model throws away most of the speed. If the computer sits under a desk, a version with an extension cable or an external antenna will hold the signal better.

Frequently asked questions about TP-Link TL-WN781ND

Are drivers needed?

On current Windows versions most models are recognised as soon as they are plugged in. For full speed and the extra features, download the driver for your model from the TP-Link site.

Will the speed match the router?

If the adapter standard or band is lower than the router, the adapter becomes the limit. That is why the adapter is matched to the router — a Wi-Fi 6 router deserves a Wi-Fi 6 adapter.

USB or PCIe for a desktop?

A USB adapter is convenient and moves between computers; a PCIe card gives a steadier signal and room for an antenna. If the computer stays in one place and you can open the case, PCIe gives the better result.

What about warranty and delivery?

The device is sold by the official TP-Link partner in Azerbaijan with official warranty. Delivery in Baku is available and shipping to the regions is possible. If you need installation, see our services page.
