Network Connection Issues Possibly?

[Bjordn]

Hi guys

So recently I bought a switch to set up a wired connection with my chromecast as well as my PC. 
Since about then, I've had a number of connection issues. Firstly, when casting local videos/movies to my chromecast from my pc, I get random audio cut outs and video freezes to the point where I have to restart the video. Before getting a switch, this never happened.

In Heroes of the Storm, the store no longer loads for me. It says 'unlocking temporarily unavailable', and I can't select any customization options for my heroes. In CSGO, the main menu news doesn't load, in League of Legends, the main menu doesn't load. I can still play games, but I'll get random lag spikes every so often. 

I've tried all the standard stuff, like resetting my router, disconnecting the switch and going back to my normal connection, basically, I've tried to set everything to the way it was before, but nothing changes. I've also tried using the ipconfig /release, ipconfig /flushdns, ipconfig /renew commands, which was to no avail.

I assume I have somehow messed with some network settings and now everything's playing up, but I can't figure out what.

 

I'm stumped. Would greatly appreciate any help or directions to help fix these issues.

Need more info, things like hardware models.

So, I've been using a Powerline adapter that has worked very well thus far, its a tp-link av600 (https://www.tp-link.com/au/products/details/cat-18_TL-PA411KIT.html) I believe. 
The switch I've picked up is this one https://www.officeworks.com.au/shop/officeworks/p/d-link-5-port-gigabit-switch-dgs-1005a-dldgs1005a
And I have a chromecast ultra which has the built in ethernet port. 
My network drivers are all up to date too.

What is your topology?  What are the power line adapters connecting?

If you have an available laptop, I would suggest that you perform a test at your modem, another at the output side of your PowerLine adapter and a third after the switch all via a Hard Wired connection and compare the results vs your rated internet speeds.
