Compact USB Wi-Fi adapter

The TP-Link TL-WN725N is a nano-sized USB 2.0 wireless adapter that adds 802.11n connectivity to desktops or laptops. It targets users who need a basic 2.4 GHz link for web browsing, email and light streaming on Windows 7, Vista or XP systems.

Low-profile thermal design

With an internal antenna and a tiny 18.6 x 15.0 x 7.1 mm body, the adapter draws power directly from the USB port without a separate supply. It runs silently, produces negligible heat and maintains a maximum EIRP below 20 dBm across 11b, 11g and 11n rates.

Plug-and-play build integration

The device occupies a single USB 2.0 port and protrudes only 7.1 mm, leaving adjacent ports free and suiting cramped chassis or mobile use. A 14-language utility CD and software WPS simplify driver installation and network setup, while Soft AP mode enables internet sharing without extra hardware. Not suited for builds requiring 5 GHz band support or aggregate throughput above 150 Mbps.

Questions about this item

How do I install the TL-WN725N and what step do people miss?

Plug the nano adapter into a USB 2.0 port, run the 14-language utility from the auto-run CD before connecting, then select your network; skipping the driver install first is the common error.

What maintenance or replacement will the TL-WN725N need later?

No user-serviceable parts exist; the internal antenna and USB 2.0 interface are sealed, so only driver updates for Windows 7, Vista or XP may be required over time.

What limit appears first during sustained use of the TL-WN725N?

The 150 Mbps Wireless N ceiling and 2.4 GHz band congestion cap throughput well before the <20 dBm EIRP or USB 2.0 bus become bottlenecks.
