Windows 7 Windows 7 issue

Hello everybody - and sorry if I posted this in the wrong place

My issue is that my connection keeps leaving me. I can just be there on Steam or on YouTube and in the next half-hour, my connection changes to "limited connection".

This issue is really troublesome, I have had it for the longest time now. I even upgraded to W10 in hopes that it will go away, but it didn't. Now I am back at Windows 7 and I can't play/study without losing my connection occasionally.

The connection is wireless, with the router being in the next room. It's a really good router and I have had no issues with my PS4 or my laptop so it can't be that.

My network adapter - Ralink 802.11n Wireless LAN Card

I don't know if it's the device itself, or it's a driver issue, but Windows says the device is "up to date".

The driver date is 11/25/2014

and the driver version is 5.0.52.0

Please help me, somebody... I can't really do this anymore and I am really thinking of going back to Linux Mint if I can't solve this issue.

I'm so desperate enough to even try one of those auto-driver installers...

Please help me...
