Pro Max Slim FCS1250, does not recognize new Intel WiFi7 BE211 Card
Hello,
I own an Pro Max Slim FCS1250 and recently installed a new Intel BE211 WiFi 7 M.2 card into the motherboard slot.
I have downloaded and installed the latest drivers from Intel; however, the card is not functioning properly.
In Device Manager, the device appears with a yellow warning triangle.
Could you please advise me on how to resolve this issue?
Thanks

I bought the older BE200 and now its working without any probelms. Yes the new BE211 is not compatible with FCS1250.
Thanks everybody

I do not see Intel Wi-Fi7 BE211 on the Pro Max Slim FCS1250 parts page. I see =
DT7J9 M.2 Intel WiFi 7 BE200
71XND M.2 Qualcomm WiFi 7 FastConnect 7800
When installed in #19, did it click into place and feel fully seated?
In the BIOS--> Devices Information--> Wi-Fi Device (page 124), what does it show?

I think the issue is incompatible with your newly added wireless card, ...and recently installed a new Intel BE211 WiFi 7 M.2 card into the motherboard slot.
The BE211 is CNVio3, which require the M.2 slot with E key and supporting CNVio3 standard. Part of the WiFi logic is embedded within the CPU Platform Controller Hub (PCH) rather than the card itself.
Solution, exchange the BE211 card for a BE200 or BE210 for your wireless upgrade.

BIOS--> Devices Information--> Wi-Fi Device. It shows Intel Wireless and the MAC adress is recognised correctly.

@Chino de Oro , @dodo34 ,
Incompatible that way or another ...
That is why I always attempt to upgrade to match a possible shipped config. As @DELL-ChrisM2 posts ...

Another reason is you are likely trying to use the existing antennas, and they can really only be built and tuned to work with a certain class of radio.
People give HP a hard-time for White-Listing M.2 WiFi cards for their laptops, until they realize why (we all want it to actually work properly and fully).
