Unable to access Internet from gs105 unmanaged switch

Basically the title. Purchased the switch with the intention of using it to have access to more internet-capable ports in my room, so that I wouldn't have to contantly swap the cable from device to device.

Outside of the switch; I cobbled together a photo of my houses topology in case that matters: https://imgur.com/a/D9wIIns

There are other devices in the house, but they all run off of wifi.

Plugged it in, set it up, and no matter what I've tried, my PC (which I am using as my Control among other things) is unable to resolve an IP.  It keeps informing me that the "Ethernet" connection is unable to resolve an IP, or similar.

• Cables are all fine
  • All of them are new.
• Switch is new, only a day old at this point
• my PCs NIC is fine as well
• my PC can access the internet just fine on its own.
  • It is only when I attempt to access the internet on my PC through the Switch, that it is suddenly unable to resolve an IP
• Router is DHCP enabled, and nothing is statically assigned.

I am not sure what mistake I made, if any. I am also not sure what all else I need to try.

What have I done wrong here?
