Can't activate wifi Realtek 8852BE

[matrag]

Hi,

I've just installed Proxmox on a NUC with a wifi chipset Realtek 8852BE. The interface wlp3s0 isn't working at all.

I'm a beginner in linux type OS.

here the lspci commande :

lspci -nnk | grep 0280 -A3

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8852BE PCIe 802.11ax Wireless Network Controller [10ec:b852]

Subsystem: Realtek Semiconductor Co., Ltd. RTL8852BE PCIe 802.11ax Wireless Network Controller [10ec:b852]

Kernel driver in use: vfio-pci

Kernel modules: rtw89_8852be

here the dmesg command :

dmesg | grep -i rtw

[ 2.992926] rtw89_8852be 0000:03:00.0: loaded firmware rtw89/rtw8852b_fw-1.bin

[ 3.461226] rtw89_8852be 0000:03:00.0 wlp3s0: renamed from wlan0

The wlp3s0 doesn't appear in ip address command. So the command ip link doesn't work :

ip link set dev wlp3s0 up

Cannot find device "wlp3s0"

What should I do ?

Thank you !

Proxmox does not support WiFi (since it cannot be used in bridge mode for VMs). Maybe you can set it up following the Wiki ( https://pve.proxmox.com/wiki/WLAN ) and other forum posts about it.

Thanks for your answer !

I've already checked WLAN wiki, but i even can't set the interface up.
Maybe a driver problem (as it worked on the preinstalled Windows 11 before I switched to Proxmox).
I only want to use my Wifi on a dedicated VM, not for Proxmox itself.

The problem is that my Wireless Card remains down :
