Dell Precision 7680 Wifi 7 card

Hi, 

i have a Precision 7680 with the Intel AX211 Wifi Card. I bought the Intel BE200 Wifi 7 card and installed it. But after reboot I have no Wifi Adapter. The BE200 card isn't shown in the device manager. Has Dell a Whitelist in Bios for the Wifi Card?

AX211 is CNVi.  BE200 is PCIe.  They are not the same thing, even though they are physically compatible.  I don't know if anyone has confirmed that PCIe-based cards work in this slot...?  If it supports CNVi only, then AX211 is probably the only card that will work there.

Hi, 

that's a info that I don't have. I only lookt at E‐Key Layout. I don't know that the ports are different. So the AX211 is always CNVi? and the BE200 is always PCIe?

Yes.  There is a PCIe version of the AX card which is AX210.  The CNVi version though isn't a full Wi-Fi card, it's just some parts of it, and the rest is handled by the system PCH (chipset).  The Wikipedia article linked explains that somewhat.  For this reason, if you have a system with a CNVi Wi-Fi card, upgrading it might not be possible if the slot doesn't also accept PCIe.  To get Wi-Fi 7 ("BE") using presumably the BE201 card, it would have to also be supported by the chipset/PCH, which is not the case in these systems.

ah ok, after reading the Wikipedia article i understand. The AX211 card is a CNVio2 card, the BE201 is a CNVio3 card. 

The article says that CNVio1 and 2 is not compatible. So i think CNVio2 and 3 will not compatible and the BE201 card will not work.
