Problem related to wifi disconnected and disappear

Problem Description:

When I do a fresh install, the Wi-Fi works perfectly at first (I can connect, update, browse).
But after some time or after a reboot, the Wi-Fi completely disappears:

iwconfig shows wlan0 with Tx-Power = 30 dBm, ESSID: off/any

nmcli shows no networks available

rfkill shows not blocked

dmesg shows repeating errors like:

rtw89_8852be 0000:01:00.0: xtal si not ready(W): offset=90 val=10 mask=10
rtw89_8852be 0000:01:00.0: mac init fail, ret:-110

This persists even without any upgrade or kernel change. I also tried older ISOs like Kali 2024.2 (kernel 6.6.15) and got the same behavior: Wi-Fi works initially, then fails.

:white_check_mark: What I’ve Tried:

Using KDE and GNOME (same result)

Not upgrading or touching apt at all after install

Reinstalling Kali multiple times

Switching kernel (wanted to downgrade to 6.1.0-kali9 but couldn’t locate package)

Bluetooth and USB tethering (to try fallback internet)

:red_question_mark: My Questions:

  1. Is this an issue with the driver (rtw89_8852be), kernel, or something to do with suspend/power management?

  2. Does installing Kali on external SSD (via USB 3.0) affect Wi-Fi driver stability

2

set up wpa supplicant then it will reconnect after reboot

First off, Realtek are not the most compatible with Linux, they can often be problematic.

You haven’t actually said if Kali is running directly on hardware (which I’m assuming from your posts) or from a VM

And if hardware, is the wifi an inbuilt PCI card or are you using a USB plug in Wifi dongle?

From a driver perspective, it doesn’t make a difference, but from a power settings point of view could be very relevant.

The fact it works initially and then stops working is odd, but would need more info to try and help you figure out what is happening.

Getting all the devices working with Linux has always been at times frustrating, don’t give up else your back to wind-blows land
