I am wondering if there are any M.2 compatible wifi cards for my HP Elitebook 840 G4. I was hoping to upgrade to 802.11ax standard. I was looking in particular at the OKN WiFi 6 AX200 M.2/HGFF 2230 card on Amazon. Are there any known working wifi cards for the 802.11ax standard for this laptop?
Here is what I ordered from Amazon - WIFI 6 AX200 M.2 card with Bluetooth 5.1 $18. I had to download new Intel drivers for both WiFi and Bluetooth from Intel's site. I used the program LAN Speed Test to get some comparison benchmarks. Using my original WiFi M.2 card that came with my HP 840 G4 I got these results Writing: 922Mbps Reading: 3257Mbps. Using the new Intel AX-200 based card I got Writing: 3,526Mbps Reading: 6,480Mbps. Quite an improvement. I did both these tests using my newly acquired UniFi 6 Lite Access Point. Money well spent on both the card and new AP.
