Report ID: TEND-W311MI-2025-01 Date: [Current Date] Subject: Evaluation of driver support, OS compatibility, and deployment solutions for the Tenda W311MI Wireless USB Adapter. 1. Executive Summary The Tenda W311MI is a compact, low-cost, nano-sized USB 2.0 Wi-Fi adapter (150 Mbps, 802.11n). Its primary challenge is poor native driver support on modern operating systems, specifically Windows 10/11 (x64) and recent Linux kernels. The device uses a MediaTek MT7601 chipset, which requires specific legacy or community-signed drivers. This report identifies the correct drivers, security considerations, and installation procedures. 2. Hardware Identification | Attribute | Specification | |-----------|---------------| | Manufacturer | Tenda | | Model | W311MI (V1, V2, V3 – V3 most common) | | Chipset | MediaTek MT7601 (also seen as RT5370 in older revs) | | Interface | USB 2.0 | | Max Speed | 150 Mbps (1x1 MIMO, 20/40 MHz) | | Frequency | 2.4 GHz only | | USB VID/PID | 148f:7601 (check via lsusb or Device Manager) | Critical Note: Verify your device’s VID/PID. Counterfeit or revised versions may use 148f:2878 or 0bda:8179 (Realtek). This report focuses on 148f:7601 . 3. Driver Compatibility Matrix | OS Version | Native Support | Driver Required | Stability | Notes | |------------|----------------|-----------------|-----------|-------| | Windows 7 (x86/x64) | Partial | Official Tenda v1.0.0.33 | Good | Works out of box with provided CD | | Windows 8 / 8.1 | No | MediaTek MT7601 driver v5.1.24.0 | Moderate | Requires manual install, disable signature enforcement | | Windows 10 (21H2+) | No | Modified driver (v5.1.27.0) | Fair | Driver must be manually installed via Have Disk | | Windows 11 (22H2+) | No | Same as Win10 v5.1.27.0 | Poor | Often breaks after Windows Update; requires reinstall | | Linux (kernel 5.4+) | No | mt7601u (staging driver) | Good | Works after firmware install ( mediatek/mt7601u.bin ) | | macOS (10.15+) | No | Community (Chris1111 Wireless Utility) | Unstable | Not recommended for production | | Android (via OTG) | No | Requires kernel module | Rare | Only custom kernels with MT7601 support | 4. Recommended Drivers by OS 4.1 Windows 10 / 11 (Primary Focus) Source: MediaTek MT7601 driver v5.1.27.0 (modified INF for Win10/11) lsusb | grep "148f:7601" If missing: # Install
