ProxMox with WiFi

To get started with Proxmox and connect it to your WiFi network, begin by installing Proxmox using a wired connection, as this is a requirement for the installation process and initial setup.

Once the installation is complete, access the Proxmox shell and navigate to the /etc/network/interfaces file. To enable WiFi connectivity, add the following configuration:

iface wlp2s0 inet manual
        wpa-essid WIFI-SSID
        wpa-psk WIFI-PASSWORD
auto vmbr1
iface vmbr1 inet static
        address 192.168.1.40/24
        gateway 192.168.1.1
        bridge-ports wlp2s0
        bridge-stp off
        bridge-fd 0

Replace WIFI-SSID and WIFI-PASSWORD with your actual WiFi network's SSID and password. You may also need to adjust the subnet settings (address and gateway) to match your router's configuration.

After adding this configuration to the interfaces file, restart your Proxmox server. Once it's back online, you should now be connected to your WiFi network. With this setup, you can proceed to create virtual machines (VMs) using the vmbr1 interface. If needed, you can safely disconnect the wired connection, and your Proxmox server will continue to function using the WiFi connection.
