If the ports pins visually look good then strong chances it’s the M92 IC, like I’m 99% confident it is. It’s a relatively easy thing to replace however without the tools or some magnification it may prove difficult, especially if you’ve never done anything like this before.
I can confirm what Michael has said and it is most likely the wifi IC underneath the EMMC chip. I have had several repairs come to me with this fault and each time it was a successful repair. Some people report that it can be a software fault and trying to boot into recovery to restore the switch and fix it but if you boot into recovery and it’s still an orange screen then you can confidently assume the wifi IC is bad. A quick reflow may bring it back to life to confirm but you will need to replace it regardless.
Here is the part here for anyone interested: https://uk.rs-online.com/web/p/pcb-headers/6832285/?relevancy-data=636F3D3126696E3D4931384E525353746F6... For a US store just google the Part Number: 292207-4 and select your desired US store. Will need to bend the pins out but this seems to be an exact match.
