Report: Feasibility and Limitations of Using TP-Link TL-WN722N with Android

Prepared for: General Inquiry
Date: [Current Date]
Subject: Driver compatibility, requirements, and practical use cases for the TL-WN722N on Android OS.

Issue 2: Interface appears, but no scan results

• Cause: Regulatory domain mismatch. Android defaults to strict region codes.
• Fix: Run iw reg set US (or your country code) and iw dev wlan1 scan to force scanning.

2.1 Version 1 (V1)

• Chipset: Atheros AR9271.
• Kernel Module: ath9k_htc.
• Android Support: High. The Atheros chipset has historically excellent support in the mainline Linux kernel. If the Android kernel includes the ath9k_htc driver, this version is typically "plug-and-play."

6. Limitations & Warnings

• No Plug-and-Play: Cannot simply connect via OTG and expect Wi-Fi settings to show a new adapter.
• Power Draw: The TL-WN722N may draw up to 500mA. Some Android phones cannot supply enough power over OTG without a powered USB hub.
• No Android GUI Integration: Android’s Settings app will never manage an external Wi-Fi adapter. All control must be via command line.
• Version Confusion: Most TL-WN722N units sold today are v2/v3 (Realtek), which are nearly useless for Android.
