The ipTIME AX7800M-6E is a Wi-Fi 6E router, featuring four Gbit LAN ports, a 2.5Gbit WAN port, and a single USB 3.0 port.

Important: The router will automatically reboot if no file is uploaded within 55 seconds.

1. Download the OEM recovery software (ipTIME Firmware Wizard(11ac)) from the manufacturer's website
2. Download the OpenWrt factory image.
3. Press and hold the reset button, then power up the router.
4. Continue holding the button for more than 10 seconds, until the CPU LED stops blinking.
5. Connect the PC to the AX7800M-6E (e.g. LAN Port 1).
6. Run the OEM recovery software and follow the instructions.
7. Select the factory image during the router recovery process.
8. Wait for the router to boot from the factory image.

Important: The router will automatically reboot if no file is uploaded within 55 seconds.

A simple TFTP command can be used as an alternative to the OEM recovery software.

1. Download the OpenWrt factory image.
2. Press and hold the reset button, then power up the router.
3. Continue holding the button for more than 10 seconds, until the CPU LED stops blinking.
4. Connect the PC to the AX7800M-6E (e.g. LAN Port 1).
5. Assign the PC IP address: 192.168.0.100/24.
6. Run the TFTP command as follows:

Important: Make sure you allow TFTP protocol in Windows firewall.

tftp -i 192.168.0.1 put <path-to-factory.bin> ipTIME_FIRM_WARE

tftp 192.168.0.1 -m binary -c put <path-to-factory.bin> ipTIME_FIRM_WARE

→ generic.flashing.tftp

1. Download the OpenWrt initramfs image.
2. Connect to the serial console (115200, 8N1), interrupt the auto-boot process by pressing 0 when prompted. Your selection will be echoed, and you will enter the command-line interface, which allows you to load the image via TFTP.

   A successful interruption will present a terminal prompt that looks like this:

    MT7986> 

3. Connect the TFTP server to the AX7800M-6E (e.g. LAN Port 1).
4. Assign the PC IP address: 192.168.0.100/24.
5. Load and run the initramfs image:

   MT7986> tftpboot 0x46000000 initramfs-kernel.bin
   MT7986> bootm 

6. Wait for OpenWrt to boot.
7. Transfer the sysupgrade image to the device using scp (or a similar tool), then install it using the sysupgrade command.

 # sysupgrade -n <path-to-sysupgrade.bin> 

Alternatively, instead of using scp, you can use the LuCI web interface. Navigate to http://192.168.1.1 and log in (username root, no password). Go to: System → Backup / Flash firmware → Flash new firmware image. Select the sysupgrade firmware image, then upload and flash it through the web interface.

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

Wi-Fi 6E (6GHz) does not work out of the box on LuCI. After installation, you need to configure a few settings in the radio1 and default_radio1 sections of the /etc/config/wireless. Once you have made these changes, you can enable and use Wi-Fi 6E.

In the radio1 section, you need to add three common options:

• band: must be set to 6g
• country: a valid country code for the 6GHz band
• channel: a preferrend scanning channel (PSC) for 6GHz

In the default_radio1 section, you need to add the SSID and key:

• ssid: The public name of your Wi-Fi network
• key: The Wi-Fi password
• encryption: must be set to either sae for WPA3 or owe for OWE (open network)

Example:

config wifi-device 'radio1'
        ...
        option band '6g'
        option country 'KR'
        option channel '37'
        ...

config wifi-iface 'default_radio1'
        ...
        option ssid 'my_wifi_6e_name'
        option key 'my_strong_password1234'
        option encryption 'sae'
        ...

The fan speed is controlled by writing a value from 0 to 2 to the fan1_target file.

$ echo '0' > /sys/devices/platform/gpio-fan/hwmon/hwmon2/fan1_target // off
$ echo '1' > /sys/devices/platform/gpio-fan/hwmon/hwmon2/fan1_target // slow
$ echo '2' > /sys/devices/platform/gpio-fan/hwmon/hwmon2/fan1_target // fast
