R36S Internal WiFi Mod
Overview
If your R36S has the WiFi pad on the mainboard, you can solder a WiFi board on it. Known R36S types with the WiFi pad are R36S-V21 2024-12-18 and R36S-V22 2024-12-18 which are often sold by 001 Ali Choice Store, BOYHOM Store and Factory Game Direct Store.
This also applies to similar devices like the R36H, R36XX, R46H, R45H, R40XX, R40XX Pro Max. Some of these devices already come with a wifi chip pre-soldered on the mainboard.

Tutorial
Here is my version of how to solder a wifi chip to the mainboard. I never soldered in my life before, but I managed to sucessfully install a RTL8188ETV chip in the first try. Device used was a R36H with a partially broken screen (nephew dropped it a couple of months ago). Perfect for testing.
Note: It's usually adviced to fully remove the mainboard from the shell.
