Hello everyone,
Yesterday, I replaced the thermal paste of my Switch v1. However, since this replacement, the wifi does not work anymore. The console does not detect any wifi network. However, the Bluetooth works, as the wireless controllers are recognized. The console can also connect via an Ethernet adapter. I did not install a CFW on it.
Here is what I tried:
- A complete cleaning of the motherboard with 90°C alcohol,
- A reset of the console,
- Boot on Android: when I try to activate the wifi, the cursor resets, as if the wifi activation had crashed,
- Boot on Linux: no wifi chip detected.
So I am open to suggestions. I can take pictures of the motherboard, boot to Linux or Android to test.
I'm disgusted, I don't understand why such a benign operation could do so much harm to this console.
Thanks in advance for your help.

Ok, so I got a phone call from the repair shop I sent my Switch in.
Turns out that two resistors were missing from the board nearby the metal enclosure where the processor is. I must have ripped them while taking apart this enclosure.
They replaced them (fortunately the PCB didn't have apparent damage), and now everything works!

So, if that ever happen to you, check if all resistors are in place!

Almost every guide to disassemble the switch warns you about that two resistors and tells you to DO NOT pry near to they. Most of the guides even shows better places to pry

It's really nice to say that but could you at least send the link of one of these guides mentioning it? That would be helpful.

Instead of being condescending to me, make yourself useful by linking to a tutorial that deals with the metal plate over the cpu and specifically points out the danger concerning these resistors.

Check SX core installation pdf. It will show the left resistor on the apu shield
