Wifi connection lost when power adapter is connected

Hello everybody and thank you in advance for your time.
My name is Katia. It's been a while, my beloved laptop Lenovo Y50 running Windows 10 pro, keeps losing wifi connectivity a couple of minutes after I plug it in. It works normally once I disconnect the power adapter.
I believe this problem started after some update but, for some reason, I can not roll back time to reverse it.
By now, enough time has gone by (a few months) that I don't even know it would make sense to try rolling back. .
Any help and ideas on how to solve it would be much appreciated. (My computer expertise is at medium - regular user - levels, so please, take this into account if you try to explain how to go about solving this.
Thanks again!!

If the ipconfig was done when it's not working it shows you have the correct IP so it's not dropped the connection

@Superfly - before I buy a new adapter, is there anything else I might try, in case this isn't the problem?

@Samuria - yes, it's not losing the connection, it's losing the internet - so it says "connected, no internet" ... what should I do?

...it's just weird that the power should affect the WiFi signal?

Yes, I know, I was thinking the same thing. Do you think, if
I try and reinstall windows and everything else, is it possible the problem might just as strangely disappear?
