15 R3, WiFi connects and disconnects after less than a minute

Hello I have an alienware 15 R3 a while back it started not connecting to the internet when i do it connects for a few seconds then it disconnects when I try to connect again it doesnt show the networks again, it works only with my mobile hotspot. other than that any connection to any wifi it does the same thing, I tried every single fix on the internet but it doesnt work at all. should i just get a wireless adapter or is ther a fix?
