Random Disconnects Windows 10

When using my phone as hotspot to connect desktop too, I get random disconnects from the internet when using Windows 10.
It worked fine for the first week but now it disconnects after seconds, reconnect lasts maybe 10 or 15 seconds.
I played around other day and got it to stay on-connected, tried to do the same thing, no work.
Other devices will stay connected...using other to write this.
New to windows 10, quick study, when have net, lol
