I'm having a really odd and frustrating WiFi problem on my Mac running high sierra. I didn't change anything and all of a sudden, it's saying no signal, and when I try to connect, it says try moving closer, I'm virtually on top of my router, I can't move any closer! The only thing that seems to help is to remove the network and then add it again which is a pain because the password is rather complicated and forgettable. I don't think the problem is my router, because I'm connected on my other devices. Any help would be appreciated, as I'm almost to the point of pulling my hair out, and I doubt I'd look very good bald, lol.

A few things to try
Hi. I don't know if upgrading your version of Mac OSm since high sierra is I think two below catalina. Besides that, Google can help with interesting fixes. also have you checked your Router's firmware? It might need an upgrade. She says realizing it's been ages since she did it. Lol. Anyway i'm sorry I'm not much more help. Sometimes these things can just disapear. Hope you get it fixed. If you need help let me know.
There is a Dongle for that
Sometimes getting a USB WiFi dongle will help.
