Laptop for sale for parts or repair please read

I bought this Samsung galaxy book laptop about 2.5 years ago fantastic laptop , but a few months ago when I reset it to sell it and decided not to sell it when I tried to get back on it it won’t let me connect to WiFi? Although there is a strong WiFi connection all around the area it’s giving me absolutely no WiFi to connect to, could be a WiFi chip error or something I’m not sure so selling for parts or if your willing to repair yourself, I’ve had no other issues with the laptop and it worked fantastic, please don’t ask me lots of question as I’m really unsure what’s happening with it and don’t know much about laptops at the time I spent 400 euro on it. In great conditio besides a few scratch’s on th front but there barely noticeable, and ignore the black mark on the front is from a sticker and will be removed check the serial numbers and imei if you wish
