Yeah good call. you can try L4T ubtuntu to test the wifi out, if it doesn’t work there then I would say it’s an issue with the IC itself and I’d swap it out
Reballing didn’t help. Problem is that it has Broadcom BCM4356 which is not so common and all of my donor boards have Cypress ICs. These ICs’ has to be taken from donors otherwise they don’t work…
That’s fine, they’re interchangeable. One company just took over the other or merged, the chips themselves are the same 
Yeah for sure they’re interchangeable… that guys wrong

So I have an oled switch same problem, what I’ve found is there is supposed to be two resistors left side of the the cpu, side by side make sure they both are there. I wiped one away with a q-tip.

I took the Cypress Wifi/BT IC from Lite, reballed it and soldered it in place… still the same error dang. joy-cons and bluetooth work fine. No shorts around the IC. i’m guessing the problem is not in the wifi/bt chip.
Hmm 
I suppose this explains the error which I haven’t personally seen before.
I made a post here a while ago detailing the location of some BT/WIFI enable test points, might wanna see if you can find that and tack a wire onto this WIFI reg enable TP and see if it’s high following prompting to boot, this may shed some more light on this (?)
Good stuff glad you got it sorted
Sorry I should have mentioned the previous poster was reffering to caps and not resistors to save you the wild goose chase 
If I remember correctly, the last time I had an issue with these caps it was halting at the second boot logo and not an error message so perhaps something has changed in the OS… good to know
it’s wi-fi ic problem , i fix a lot of this error code faulty switch , just don’t simply just try replace one or two , u should order from alibaba 4-5 to fix it , normally it won’t fix just replace one , alot of faulty or not working wifi ic for this type of crystal type ic .
hi i have the same pb , what capacitors are they pls
i changed the ic chip , replace the 2 caps near the cpu but i still have the same wifi error code. All the rest is working fine though. Any original ideas ?
Hi Friend, i have the same problem, so you know this caps value for i buy the correct?
Do you find the capacitors value?
No i just took them from a defaulted morherboard
Hi, there’s a topic on reddit mentioning those, I can’t post links as I’m new here but the topic name is
“Nintendo Switch Capacitor Identification, left side APU - Anyone know where I can buy this part and what model it is?” you can find it easily with google.
They should be 100nf 10v 0201
