Hi everyone,
I'm experiencing a serious issue with my ASUS laptop and would appreciate help from anyone familiar with this problem.
Laptop model: ASUS ExpertBook BM1503CDA
OS: Windows 11 Home, version 25H2
Wi-Fi adapter: Realtek RTL8852BE Wi-Fi 6
The issue: Whenever I connect to certain Wi-Fi networks or mobile hotspots, the laptop crashes and restarts instantly. This happens right at the moment it connects. If "Connect automatically" is enabled for that network, the laptop enters a constant reboot loop, making it unusable until I turn off the router or hotspot to prevent it from reconnecting.
This doesn’t happen on every Wi-Fi network. Most Wi-Fi connections work fine — but some trigger the crash every time, consistently.
Additional symptoms:
After a few forced restarts, the system eventually prompts for a BitLocker recovery key, and some drivers appear to get corrupted or need to be reinstalled manually.
The crash consistently shows the following error:
Stop Code: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E)
**What failed:** `ndis.sys`
I've already updated Windows and all ASUS drivers to the latest available versions. Unfortunately, the issue persists.
Has anyone experienced this with Realtek RTL8852BE or ASUS ExpertBook series? Any suggestions on how to resolve this — driver updates, BIOS settings, workaround tips — would be greatly appreciated.
Thanks in advance for any help!

Hi,
Did you update the BIOS on your laptop?
Could you do a test? I know there's a problem I saw with Intel Wifi 6 AX201, I don't know if it's the same thing, but try connecting to a 2.4 GHz network and see if the crash occurs instead of 5 GHz.
If possible, without automatic switching, you can try using the phone.
Regarding the drivers, did you install the driver directly from the Asus hub or did you install it manually?
Thanks
Hi,
yes, I did update the BIOS.
I am connected to 2.4 GHz, this router doesn't have 5 GHz.
My phone use this same wifi signal normally.
Drivers I did install with software MyASUS (I think this is the best way).
Same problem I have also on hotspots from some mobile phones. Simply is not possible to use it, but of course not on all phones.
Do you have some additional advice for me? This is killing me....
Thanks.
Even when I take ethernet cable from router and connect it directly to my laptop - it doesn't work. But in this case there is no restart, just blinking of the small ethernet icon on the taskbar.
Hi,
In the case I described, it was a hardware issue and I needed to replace the network card. However, if I understand correctly, when connecting the network cable, there is no connection?
Thanks
Hi,
Yes, there is no connection when I connect ethernet cable directly to my laptop. Ethernet icon on taskbar first is blinking and then turn off the icon - no connection. But important fact is that I am using this wifi with my phone and everything is ok. It is not first time that I have such problem with my laptop. Solution for this I can not find nowhere on the internet.
Is it possible to solve this problem with external wifi adapter?
Hi,
Logically yes, but it's very strange that this laptop is still under warranty?
Thanks
Hi,
yes, this laptop is still under warranty. It is bought in august 2025 and there is 3 years of warranty.
Hi,
I checked the support on the ASUS website and found two firmware updates for your laptop that might solve the problem. As a precaution, you should do the following: disable BitLocker and update both your laptop's firmware.

Update the BIOS if it's not the latest version. Drivers: https://www.asus.com/laptops/for-work/expertbook/asus-expertbook-bm1-bm1503/helpdesk_download?model2Name=BM1503CDA

After that, reinstall the network chipset drivers.
AMD Chipset
Realtek Bluetooth® Driver
Realtek LAN Driver
Open the command prompt (admin) and run the commands: sfc /scannow and dism /online /cleanup-image /restorehealth. Wait for the process to finish and restart the computer.
Then perform a clean boot and uninstall any unused applications you may need.

Please test and let me know.

Hi,
I did not try your solution. It is to complicate for me, I am not such expert.
I bought externall wifi adapter and still doesn't work, again system shut down immediately after connection.
But there is one improvised solution that solved the problem. I connect my samsung phone to the wifi network and share this same network with my laptop trough usb cable (usb sharing must be turned on). Finally I have a cure for my laptop. :)
