I have run into a dead end here. I am trying to install an Intel AX200 WIFI + Bluetooth network card onto my desktop PC. I connected it to a PCIe port that had more slots than needed but I read that this should be fine. Additionally, a cable from the network card was connected to one of the USB inputs of the mainboard for the Bluetooth. My problem is that I never got the WIFI to work (only the Bluetooth).

What I tried on windows: On Windows, the device is found in the device manager. I have installed the newest drivers and later checked if they are up to date using the Intel Driver Support Assistant. The Bluetooth drivers instantly functioned as intended. However, the WIFI drivers never really worked. I tried reinstalling them a couple of times. Sometimes they did not work at all (Code 10 error in device manager), sometimes there were no errors and it even showed some of the available wifi networks, but I could not connect to them.

What I tried on Ubuntu: To further trace the error I also tried the same things on Ubuntu. Here the drivers installed automatically with the system update and I am on an up to date kernel version 5.3.0-42-generic. I also found the up to date drivers (same as on Intel's download page) in /lib/firmware. By all means, it feels like I have the up to date drivers installed. lshw -C network returns the following

   description: Network controller
   product: Intel Corporation
   vendor: Intel Corporation
   physical id: 0
   bus info: pci@0000:01:00.0
   version: 1a
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress msix bus_master cap_list
   configuration: driver=iwlwifi latency=0
   resources: irq:16 memory:f0100000-f0103fff

   ....other network devices follow...

This also looks like the drivers are properly installed? Now I am wondering what I may have missed/done wrong. Of course, it is suspicious that the WiFi neither works on Windows nor on Ubuntu. The WiFi works when using another USB-WiFi Dongle.

This is what I see when trying to start WIFI

  • Could it be that my mainboard does not support WIFI 6? Or does basically every mainboard support WIFI 6 if you connect the proper network card to it?
  • Maybe I did not properly install the network card into the PCIe slot (I have no experience in installing computer parts). Then again, it looks like I can only install the card in this orientation. Could it still be installed wrong even if it already shows up on both Windows and Ubuntu?
  • What else could be causing problems?

Thank you guys for any help!


EDIT

So in the device manager I usually find the following errors. First, I get an error 430 (device needs more installations), then an error 400 with the following info (I tried translating):

The device PCI\VEN_8086&DEV_2723&SUBSYS_00848086&REV_1A\4&63638ad&0&0008 was configured.

I marked the 'device was update: false' line because it sounds suspicious. After this, I get an error 411 (there was a problem when starting the device).

By now I have so often uninstalled/reinstalled the drivers on windows that I really fear that I might have corrupted something. Can I get a more clean deinstallation of drivers then simply deleting them in the device manager?

Edit 2

Running Ubuntu dmesg |grep iwl, I found a long list of error dumps for the iwlwifi (that's the right device/driver). I of course tried googling and understand them but can't yet make any sense of them.

  • Just a thought, not a solution by any means: Have you checked into BIOS/UEFI if there's not something to activate first? I don't AsRock mobos very well, but I know they usually come with many options to customize peripherals. Plus, in Windows, have you checked Power saving options in both Device manager and Network (in the adapter properties); while you're at it, in the Details tab, does it give off any error code or not fully installed driver warning? – user1019780 Mar 28 at 15:05
  • If you were able to see Wi-Fi networks, then the card and drivers were most likely working. Did you remember to attach the antennas? The most common reason for seeing a Wi-Fi network but being unable to connect (assuming you got the password right) is low signal strength. – Spiff Mar 28 at 15:20
  • Thank you for your suggestions! I will check all of this and add information to the post. The antennas seem to be properly attatched. – daudprobst Mar 28 at 15:32
  • I found nothing in the UEFI settings that seems to have something to with the network card :/ – daudprobst Mar 28 at 15:55
  • @daudprobst: I meant "peripherals", namely PCIe ones. Nothing about how the mobo is powering them, power saving settings or anything? Legacy mode (if such a thing exists for PCIe equipment)? – user1019780 Mar 28 at 16:54
