  filename "vmunix.passacaglia";
  server-name "toccata.fugue.com";
}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
host fantasia {
  hardware ethernet 08:00:07:26:c0:a5;
  fixed-address fantasia.fugue.com;

# You can declare a class of clients and then do address allocation
# based on that.   The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.

class "foo" {
  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";

### Change Driver Build Type (Optional)

Source: https://context7.com/aircrack-ng/rtl8812au/llms.txt

Optionally modifies the driver's Makefile to build it as a built-in module ('y') instead of a loadable module ('m').

```bash
sed -i 's/export CONFIG_88XXAU = m/export CONFIG_88XXAU = y/' \
    /usr/src/linux/drivers/net/wireless/realtek/rtlwifi/rtl8812au/Makefile
```

--------------------------------

### USB Mode Switch Configuration

Source: https://github.com/aircrack-ng/rtl8812au/blob/v5.6.4.2/README.md

Unload the driver and reload it with the rtw_switch_usb_mode parameter to control USB mode switching. '0' disables switching, '1' switches from USB 2.0 to 3.0, and '2' switches from USB 3.0 to 2.0.

```sh
$ rmmod 88XXau
$ modprobe 88XXau rtw_switch_usb_mode=int (0: no switch 1: switch from usb2 to usb3 2: switch from usb3 to usb2)
```

```kconfig
config 88XXAU
	tristate "Realtek RTL8812AU USB Wireless Network Adapter"
	depends on USB
	select RTLWIFI
	select RTLWIFI_USB
	help
	This is the driver for Realtek RTL8812AU USB
```

--------------------------------

### Configure Wireless Interface TX Power

Source: https://context7.com/aircrack-ng/rtl8812au/llms.txt

Adjusts the transmission power (TX power) of the wireless interface. You can set a fixed power level or revert to automatic power management. Verify the current TX power setting.

```bash
# Set TX power to 30 dBm (3000 mBm)
sudo iw wlan0 set txpower fixed 3000

# Verify current TX power
iw dev wlan0 info

# Set to automatic TX power
sudo iw wlan0 set txpower auto
```

--------------------------------

### Remove RTL8812AU Driver

Source: https://github.com/aircrack-ng/rtl8812au/blob/v5.6.4.2/README.md

Execute this command in the source directory to remove the driver from your system.

```bash

```

--------------------------------

### Assign IP to WLAN Interface

Source: https://github.com/aircrack-ng/rtl8812au/blob/v5.6.4.2/docs/linux_dhcp_server_notes.txt

Assigns a static IP address to the wlan14 interface. This IP address should be within the subnet configured in dhcpd.conf.

```bash
ifconfig wlan14 192.168.1.254
```

--------------------------------

### Disable Random MAC Address in NetworkManager

Source: https://context7.com/aircrack-ng/rtl8812au/llms.txt

Configure NetworkManager to use a fixed MAC address instead of randomizing it for Wi-Fi connections. This involves editing the configuration file and restarting the service.

```bash
# Edit NetworkManager configuration
sudo tee -a /etc/NetworkManager/NetworkManager.conf << 'EOF'

[device]
wifi.scan-rand-mac-address=no
EOF

# Restart NetworkManager
sudo service NetworkManager restart

# Verify configuration
cat /etc/NetworkManager/NetworkManager.conf
```

--------------------------------

### Disable Random MAC Address in NetworkManager

Source: https://github.com/aircrack-ng/rtl8812au/blob/v5.6.4.2/README.md

Prevent NetworkManager from using random MAC addresses by adding a configuration line to NetworkManager.conf and restarting the service.

```ini
[device]
wifi.scan-rand-mac-address=no
```

```bash
$ sudo service NetworkManager restart
```
