Benefits & Use Cases
Improved Wi-Fi range: The external high-gain antenna helps in connecting to routers or access points located far away or through obstacles.
Plug-and-play simplicity: USB interface with cross-platform support and easy WPS setup.
Better performance than onboard Wi-Fi: Particularly useful if your device’s built‑in adapter is weak- outdated- or unstable.
Budget-friendly: Offers a solid balance between price and performance in the N150 category.
Compatibility with legacy networks: Works with older 802.11g/b networks while offering upgrade potential through 802.11n.
Limitations & Feedback
2.4 GHz only: Does not support 5 GHz Wi-Fi- so it won’t reach modern AC or AX speeds
Real-world throughput lower: Typical actual speeds are about half the theoretical 150 Mbps—expect around 60–80 Mbps in optimal settings.
Driver & version variations: Later hardware versions (v3+) use Realtek chipsets that may not support monitor mode or packet injection used in penetration testing. Only v1/v2 officially support these features.
Connection stability issues: Some users report dropouts- USB connector wobble- or low throughput. A USB extension cable helps mitigate port interference.
Questions & Answers
Q: Why should I use this adapter instead of built-in Wi-Fi?
A: The TL-WN722N offers stronger external signal through a high‑gain antenna- potentially outperforming weak or damaged internal modules. It also works across many platforms with easy USB setup.
Q: Can I reach 150 Mbps speed in real life?
A: Speeds up to 150 Mbps are theoretical. Real-world tests usually yield around 60–80 Mbps- influenced by interference- router type- and USB port speed.
Q: Does it work for Wi‑Fi penetration or monitor mode?
A: Only older versions (v1/v2) support monitor mode and packet injection. USR market units (v3+) may lack these capabilities without custom drivers.
Q: Is it reliable long-term?
A: Generally yes—many users report solid performance at an affordable price- though some note physical connector wobble or lower than expected speed. Using the included extension cable improves stability.
