OpenWrt MT7610U AP Install and config AP

1. ⚙️ Hardware & Driver Installation

The core task was installing the correct drivers and firmware for your MediaTek MT7610U chipset (Vendor ID 0b05:17d1).

  • Driver: Installed the kernel module responsible for the MT76x0 series USB chips:
    • opkg install kmod-mt76x0u
  • Firmware: Installed the required binary data for the chip to function (named for a similar chip in the family):
    • opkg install mt7601u-firmware
  • AP Management: Installed the daemon necessary to run a Wi-Fi Access Point and handle modern encryption:
    • opkg install hostapd-wolfssl (Chosen for full WPA3 support with a lightweight security library.)

2. 🔒 Wireless Security (Encryption)

You selected the strongest security suitable for a simple, password-based AP.

  • Protocol Choice: WPA3-SAE (Simultaneous Authentication of Equals).
  • Reasoning:
    • Simplicity: Uses a passphrase, eliminating the need for a complex RADIUS server (which would be required by WPA3-EAP/Enterprise).
    • Security: Provides modern protection against offline dictionary attacks, which WPA2-PSK is vulnerable to.

3. 📶 Wireless Mode & Compatibility

You successfully configured the AP to run on the 2.4 GHz band while maintaining compatibility for legacy devices.

  • Band: 2.4 GHz (Chosen for better range and penetration for remote management).
  • Mode: N (802.11n).
  • Compatibility: Selecting N mode allows all modern 802.11n devices to connect, while simultaneously enabling 802.11g mode, ensuring your older 2.4 GHz-only client can connect successfully.
  • Channel Width: (Implicitly or explicitly set to) 20 MHz (HT20) for maximum stability and compatibility in the congested 2.4 GHz band.
