How can add wifi support at MT7622 in @frank-w 's , image with Debian 10 and 5.10 kernel? Where are the correct kernel headers for this one?
you find kernel-headers in my github-repo as releases…just search the release with your current kernel-version. maybe upgrade kernel to a newer version…what wifi-driver do you want to add? maybe you need to recompile kernel with the driver you want.
I want to add MT7622 integrated wifi , I’m not sure wich is the correct driver… , I’m trying to solve wlan0 interface is not present…
driver should be included…have you tried loading mt7615e module? maybe firmware is missing
AFAIK mt7622 internal wifi should use both CONFIG_MT7615E and CONFIG_MT7622_WMAC kernel options simultaneously (MT7622_WMAC is a suboption of MT7615E)
so if you have this module and it doesn’t work, try to check your config for the second option. And of course check for the firmware 
Right,my kernel is configured (now) to built mt7615 as module (m) with mt7622 builtin (y) Afair this was also same state when i made the image
You can try
zgrep -i "mt7622\|mt7615" /proc/config.gz
Maybe load config module first
modprobe config
