Installing and Using OpenWrt Network and Wireless Configuration
41

Okay, I now have a chance to work on this project again.

I flashed a new image with all the mentioned packages in previous comments to my build. Now, None of the radios are receiving any Wifi signal. Is it my configs that's wrong?

Here is my wireless configs

All hardware installation is back to how it was when I first started this project, and the only thing I've changed in the configs is change the country codes to match and comment which radio is which

42

Some other things that I noticed while troubleshooting: While watching the scroll of text while booting I see:

Failed to run INIT ucode: -110 openwrt
and
Failed to start RT ucode: -110 openwrt

It retries 2x's then stops. Any idea what this could be? When I Google these errors I get results for Arch linux, and then someone had the same issue with Openwrt but posted in an Intel forum and it was never resolved.

Recall:

Does your equipment support this?

This is incomplete.

From a quick search, it seems like an error from the Intel card.

We did caution you about this. Are you sure you configured the Intel as STA and the other card as AP?

The path in your wireless config shows you did not.

Sure you don't mean LAN here?

44

The encryption with "owe" I did not put that in, does openwrt load its own configs?

Is there a default wireless config that I can use as a template and make changes in the future as I learn or see a need?

45

You sure?

That's not a default configuration. The default is a [disabled] open SSID named OpenWrt.

It seems you edited the default config (and perhaps introduced errors, as I just noticed other issues, e.g., some SSID sections are missing the
config wifi-iface... line). I advise resetting the device to default to produce a default configuration. Lastly, be mindful of which PCI path is the Intel. You'll need to be certain to setup the STA on that radio.

46

Yeah I was also thinking it might be best to restore to defaults. I've learned a lot so hopefully I won't need as much help, and I come back with questions if need be. I hope to work more on this tonight.

This is a pretty common first-time OpenWrt setup issue, and you’re actually very close already.

Right now the main problem isn’t your Intel AX200 or the MediaTek MT7922e, it’s simply that OpenWrt has no working uplink, so it can’t install or even see extra wireless drivers yet. That’s why WiFi hardware looks “missing”.

Also, when you change the LAN IP, you’re likely locking yourself out because your PC is still on the old subnet, so SSH and the web UI stop responding even though the router is fine.

For your travel-router idea, the clean way is:
first get internet working through the existing repeater (as WAN over WiFi or Ethernet), then install the missing kmod packages. Only after that will PCIe WiFi cards start showing up properly.
One important note: the MediaTek MT7922e often needs newer kernel/firmware support, so on some OpenWrt builds it won’t appear at all until packages match the hardware.
