ZBook 15 WWAN M.2 slot compatibility

[js89]

Hi,

Since I'm having issues with Bluetooth on my first gen. HP ZBook 15, I'm thinking about upgrading the WLAN module. The current WLAN module is an Intel Wireless N-7260, but dispite trying all sorts of drivers and fixes I keep getting choppy Bluetooth audio and laggy mouse response.

The laptop has a PCIE half minicard socket for WLAN and a M.2 socket for WWAN. Since all newer WLAN cards seem to have a M.2 form factor, will installing a new WLAN card in the M.2 WWAN socket work? Or can you use the M.2 socket solely for WWAN?

Actually they are two different socket types called socket 1 and socket 2

Different socket types are part of the M.2 specification that requires support for specific device types within a given socket.

Socket 1 is designed for Wi-Fi, Bluetooth®, NFC and WI Gig

Socket 2 is designed for WWAN, SSD (caching) and GNSS

Socket 3 is designed for SSDs (both SATA and PCIe, up to x4 performance)

I don't think this is ging to work

Regards.

Hello

I agree it will not work.

The BIOS check also the WLAN installed , if it's not supported , BIOS will show an error at boot and you will need to remove the WLAN card , even if it's a miniPCIe one.
