Hello.
I have hAP ax3. Was firmware 7.15.1.
Updated to 7.16.1. Stopped working WiFi, in logs appeared the entry “defconf gen: unable to find wireless interface(s)”.
Rolled back to 7.15.1 - problem remained.
Reset to factory settings - did not help.
Please tell me what I’m doing wrong?
Well… Mikrotik has two (actually three) wireless drivers:
wireless - works with 802.11n and ac capable devices
wifi-qcom-ac - works only with ac devices and enables some additional features compared to wireless
wifi-qcom - works with ax devices
As Mikrotik publishes the above:
https://help.mikrotik.com/docs/spaces/RKB/pages/228655144/7.13%2Bnew%2Bwireless%2Bpackages
You currently have BOTH wireless and wifi-qcom installed, and only wireless is enabled. As written above: this DOES NOT support your device.
What you need to do: uninstall wireless and enable qcom-ac. You will need to reboot for it to take effect.
Your wifi interfaces will appear. If you want default configuration, you will probably have to do a “reset to defaults” thingy (either with reset button or from menu…)
Hope this helps!
Yes, after a few hours of experiments, I realized what had happened and corrected the situation. The model page to download offers wrong files, this is what caused my difficulties. Before the manual upgrade, I should have seen which packages are installed in this model. Thank you!
Glad it worked out.
Could you point this out to support@mikrotik.com so they can fix this.
That’s the page for AC3.
You can tell seeing arm version instead of arm64.
Different thing.
Page for AX3 is correct.
And the only correct driver for AX3 is wifi-qcom.
NOT wifi-qcom-ac.
Yep. Ax3 does have the correct packages.
I’m still at a loss as to what could have happened, because obviously arm packages wouldn’t have installed at all…
Damn it! That’s right. I made the problem myself. It was a night, I was tired. ARM packages were not installed, so I went and found ARM64, the wrong package “wireless” on inertia. Then looked at the logs that he wants “Wi-Fi-qcom”, gave him. Well and then you know.
Been there. 
Glad it’s resolved.
