Issues with my internet validation/verification not working for everything but does for certain things.

(I'm not sure if this is something that I can post here but I hope this is something that falls under this r/ ) So to keep this simple a couple days ago my internet was beginning to act up for my device which is an Alienware m15 r3 with a Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz (2.59 GHz), and 16.0 GB worth of ram as well as 8 GB for my graphics card with a total storage of 4.10 Tb worth. now my predicament is a bit....lets say strange, A couple of days ago my internet began to fail to fully connect despite showing it was connected without issue, leading to me being unable to play some of my games, however at the same time some specific games had no issue and ran perfectly. this also effected other applications such as discord there I was able to text with others while being unable to view streams and it eventually led to me being unable to join calls outright, meanwhile I was still able to text to my friends. so to put simply my internet verification is acting finicky and verifying some things while doing the opposite with others. I do hope someone out here can help me as I'm not really that aware of my system and rarely delve into it so I'm at a lose here on what to do thanks.
