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 :

mine is working just not full speed yet.
I started out with this link https://forum.proxmox.com/threads/howto-proxmox-ve-8-1-2-wifi-w-snat.142831/
then ended up using https://forum.proxmox.com/threads/howto-proxmox-ve-8-x-x-wifi-with-routed-configuration.147714/

now my issue is its only on 20MHZ and Im trying to get it on at least 80... 160MHz would be nice!

you see, the signal is strong yet 20MHz is horribly slow.
