Brief internet droppage on ethernet

My pc is the only thing hooked onto a wired connection in the house. For some reason every 30-45 my connection drops for a fraction of a second and quickly reloads which is fine if I'm just online and such but, when I'm gaming it's just enough to where the game will boot me out of the server completely. My drivers are all up to date. I'm not to sure what to even try as the problem has been going on for a while

Bad Cable, Bad NIC, bad port on your router, or bad router.

Is this still right if everything wireless doesn't have the same problems and stay connected?

Wireless can have burps and hicuos if you are using a congested channel, 2.4ghz, too far away when trying to use 5ghz. Where my two A/P’s sit in my house, I get great coverage and signal until I walk out to the workshop and then have to extend by using the mesh setup with our Comcast XB6 eMTA, which means plugging in and setting up the pucks that are only used in the Summer Months when I am out in the workshop.

Correct the only thing having hiccups is my computer which is the only wired connection, they all go to the same router.
