Proxmox over WIFI (WLAN)

Don't do that. A host shouldn't have multiple IPs assigned to the same subnet. This will screw up routing. So either use 192.168.88.88/24, 192.168.88.99/24 or 192.168.88.89/24 but only one of them. In your case you probably want to use DHCP on wlx18a6f70bc768 for the 192.168.88.0/24 subnet and some other subnet for vmbr0.

Sorry but maybe I do not get the idea how it works.
I thought that the main server IP, for example for web access, should be the WiFi interface (wlx18a6f70bc768) IP address (192.168.88.89). If I use DHCP on that then I get web access on random IP address and everything becomes a bit complicated. Am I thinking the wrong way?

What subnet should I use for Bridge (vmbr0)? Does it have any restrictions instead of not being in the WiFi interface (wlx18a6f70bc768) network?
I've got 3 IPs on the server - Ethernet, WiFi and Bridge, should I transfer the Ethernet IP to another 3rd network if I even wanna use it?
Also should router be in the fourth network or is it OK for WiFi IP interface to be router subnet (192.168.88.0/24)?

Thank you for your help with goofy questions.

Wifi usually uses DHCP go grab a IP/gateway/DNS from your local DHCP server. To then get always the same IP you tell your WifiAPs DHCP server to set a static lease for it.

Choose one based on RFC 1918. Doesn'T matter which one as long as it won'T collide with existing subnets: https://en.wikipedia.org/wiki/Private_network

Yes.

Wifi IP will have to be in your routers subnet or otherwise your PVE server would be isolated.
 
Hello, I hope my answer could be useful for those who shaking between the "What and how to configure my Wlan, routing table, and at the same time sharing internet connection to the VM's".
Here is my configuration:

auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
address 10.12.59.254/24
gateway 10.12.59.1
bridge-ports none
bridge-stp off
bridge-fd 0

auto wlp2s0
iface wlp2s0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '10.12.59.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '10.12.59.0/24' -o vmbr0 -j MASQUERADE

up route add default dev wlp2s0

iface enp0s31f6 inet manual

iface wwan0 inet manual


source /etc/network/interfaces.d/*


#/etc/wpa_supplicant/wpa_supplicant.conf

network={
ssid="Your_ssid"
#key_mgmt=WPA-PSK
psk="Your_password"
priority=2
}
 
With the proliferation of higher bandwidth WIFI protocols (i.e. WIFI6E and WIFI7) providing higher speed network throughput than wired in some WIFI7 installations, Are there any plans (ROADMAP) for Proxmox to provide support for WIFI Networks in Proxmox?

As my networking knowledge grows, and higher bandwidth WIFI protocols become more standard... there needs to be more reliable support for WIFI... if not for primary connection... at least as a redundant or fallback for wired networking.

Has anyone heard if Proxmox is working on this... or is this something needed from the upstream (Debain) source?
 
I realize this thread is a bit old now, but a simple solution is to use something similar to ASUS wireless bridge mode - other manufacturers may have another name for it.

Basically, you configure a wireless (media bridge) router to bridge to your main high-speed WIFI network, then use its LAN ports to feed your Proxmox nodes.

Super simple solution... It is future proof'd too as faster more modern network bandwidths (~2Gbps+WIFI) can be accessed even now!

Although in my case I'm using an old deprecated router that was destined for the "trash bin"! It only supports the N-standard, but I typically can live with 300Mbps without too much pain anyway - even for high-speed gaming... FREE is FREE though! :cool:

pdwittman,
I had tried this using Debian documentation to manually edit the networking files on the node to add WIFI.... and it seemed to work at first... but, my experience was that once you do any subsequent edits to the network from the Proxmox GUI, the manual changes you made to add/configure the WIFI were backed out (removed)....or made unusable after the Proxmox GUI edit. How did you over come this? Please provide examples of the configuration. Thanks.

I would love to have a WIFI connection as a backup to the Wired Ethernet on my Proxmox nodes....

You can always add

Code:
source /etc/network/interfaces.d/*

to the bottom of your interfaces file and then create a new file in the /etc/network/interfaces.d that should be left untouched by Proxmox VE
