I have a Older KOOC tablet s/n DAOKLY017541.

Yeah, it's really old. I stopped using it because it would get so hot that to cool it, I put it in the freezer! (Unplugged) It's not getting hot now. Also, now the wifi keeps disconnecting. The tablet is 5 feet from the router. I would like any info on this. I'm just getting back to this thing, I'll watch some vids of "How To Repair or Open an ASUS Tablet. Maybe I can upgrade it to work more better. Thanks for any help or flamingos, OOPS.
