MAC address
-----------
+-----------+-------------------+------------------------+
| Interface | MAC               | Algorithm              |
+-----------+-------------------+------------------------+
| WLAN 2.4G | 58:86:94:xx:xx:xx | label1                 |
| WLAN 5G   | 5A:86:94:xx:xx:xx | label2 with LA Bit set |
| WLAN 6G   | 5A:86:94:xx:xx:xx | label1 with LA Bit set |
| WAN       | 58:86:94:xx:xx:xx | label1 + 1             |
| LAN       | 58:86:94:xx:xx:xx | label1 + 3             |
+-----------+-------------------+------------------------+
The WLAN 2.4G MAC address (label1) was found in 'Factory' partition, 0xA0004
The WLAN 5G MAC address (label2) was found in 'Factory' partition, 0x4

Installation
------------
1. Download the OEM recovery software (ipTIME Firmware Wizard (11ac))
   from the manufacturer's website
2. Download the *squashfs-factory.bin file from the OpenWrt website
3. Press a reset button, and power up the router (keep pressing the reset button)
4. Wait more than 10 seconds until the CPU LED stop blinking
5. Connect the router (LAN port) to the PC
6. Run the OEM recovery software and follow the instructions
7. Select the *squashfs-factory.bin file during the router recovery process
8. Wait for the router to boot from *squashfs-factory.bin

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

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

```
cd /sys/devices/platform/gpio-fan/hwmon/hwmon2

echo '0' > fan1_target // off
echo '1' > fan1_target // slow
echo '2' > fan1_target // fast
```

Limitation: Enabling Wi-Fi 6E
----------
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'
        ...
```

Note: A list of all the 6GHz PSC channels:

```
5, 21, 37, 53, 69, 85, 101, 117, 133, 149, 165, 181, 197, 213, and 229
```

Limitation: Maximum Transmit Power (Wi-Fi 6E)
----------
The maximum transmit power is currently broken. In the drop-down menu,
you can only choose between "driver default" and "255 dBm (2147493647
mW)". There is currently no workaround for the issue. Please leave the
maximum transmit power set to "driver default".
