Elitebook 845 G7 - only 2.4 GHz WiFi and bad Bluetooth connection

[rfkd]

Hello, I just bought a used EliteBook 845 G7 notebook but unfortunately I'm having issues with both the WiFi and the Bluetooth connection on Windows 11 - the computer only connects to my 2.4 GHz WiFi network (144 Mbps, 802.11n) and my Logitech MX Anywhere 2S Bluetooth mouse stutters from time to time. The WiFi/Bluetooth module is a RTL8822CE running with the latest (?) driver version 2024.10.229.1. However this only happens on Windows 11, with Ubuntu 24.04 the notebook connects to my 5 GHz WiFi network without issues and also the Bluetooth connection is better. So apparently it's not a hardware but a driver issue. Is there any fix available?

Another option would be to replace the problematic Realtek module with an Intel AX200, AX210 or even BE200 module (or any other if there's a better one) but I'm unsure which modules are actually compatible. Furthermore I've read about issues with non-HP parts, so can I buy any of the mentioned modules in any shop or do I have to watch out for something? E.g.:

• https://www.alternate.de/Intel/Wi-Fi-7-BE200-M-2-non-vPro-WLAN-Adapter/html/product/100044899
• https://www.proshop.de/Netzwerkadapter-Netzkarte-Druckserver-usw/Intel-AX210-Wi-Fi-6E-2x2-R2-BT-53-M...
• https://www.computeruniverse.net/de/p/5003-12Z

Since pricewise they're all alike please suggest me the best option which is known to work with my notebook (with Windows 11).

Thanks a lot.

Something to do with its driver. Do you know which one on the following adapters is on your machine ?

1. Intel Wi-Fi 6 AX200 + Bluetooth 5 (non-vPro) part # L35282-002
2. Realtek RTL8822CE 802.11ac 2 × 2 Wi-Fi + Bluetooth 5 part #  L44796-002

Regards.

Thanks for your reply. Like I've written above it's the Realtek RTL8822CE. Please check my post for the details.

Can anybody tell me what's the best replacement module for the RTL8822CE for this notebook? Where can I get such information from? Would also need a (German) source to buy.

Since nobody replied I just ordered an AX200NGW on AliExpress (I didn't buy the one I linked above due to its different pinout):

It was delivered today and I installed it immediately without issues. Both Bluetooth and WiFi, finally even with 5 GHz, are working so much better now. The "SPS" number on the module was "L35282-005 0G", just in case somebody else needs this as well.
