Realtek WiFi adapter disconnecting

[_Vic_W_]

Problems disconnecting from WiFi. Default gateway not available. It's not the router, I don't have this issue with other devices.  Online fixes say to uninstall/reinstall driver and de select power management option but this only works for about 2 minutes and I have to do it all again. It's not a long term solution. I can't stay connected for more than a minute or so. I bought this on November it's a new windows 10 model not an update issue.

I have the exact same issue with a recently bought Hp15s-fq1002na and it's really annoying me, how can a brand new Laptop in 2020  have these problems?

I have tried the power management settings aswell - but the issue is still there.

My Laptop disconnected from the router again about 30 minutes ago, while all my other devices are fine,  I think it's disconnecting when the Laptop is not plugged in and is working off the battery, I am testing this theory out now as we speak, so after it disconnected this morning I went in to the battery settings > change advanced power settings > wireless adapter settings > then changed the 'on battery' from 'medium power saving' to 'maximum performance' 

I really hope this solves the problem because it's a bit of a joke, I see many threads in this forum with the same issue.

Sort it out HP.
