Think that adds further confirmation that the wifi IC is at fault.
would usually be an issue with the inner USB row of pins and/or P13 IC at fault, I would test you have continuity from a USBC breakout board from all USB lines to their destinations
It’d be a bit pointless repairing anything else on this console before repairing the wifi issues as that orange screen is only ever going to get progressively worse until it ulitimately just ends up being either a permanenet orange screen or no boot at all.
Can you provide high res shots front and back of the board, and also closeups of the following areas, M92 IC, BQ IC, Fuel gauge, P13 IC, USB area, battery connector, just incase I spot something out the oridinary
