Wired Connection KIlling Network

Wasn’t sure where to categorize this topic but I am having occasional network issues due to the mining Rig.

It will run for days or minutes and encounter this issue seemingly randomly. I have searched around and something that seems potential is a DNS issue. When I restart the rig the network immediately has no issues of returning to normal. Other PCs on the network regain connectivity instantly.

Every PC in the House is connected via ETHERNET cable and if i reboot the mining rig, internet access returns. How can I permanently solve this issue? Some vague suggestions were to /flushdns command in the miner? will this be long term/permanent fix? Is it even my problem?

Anyone else having similar issues
