Internet Connection To Wynncraft

It just started a week ago but recently I have had a ton of trouble connecting to wynncraft as a server and when I am online I experience a ton of lag. I live in the American Midwest region so I do not know if this could be weather related or anything. My brother's computer connects just fine to everything but this server as well. I have better connection off of my phone wifi hotspot than I do across a hardwired Ethernet cord to my modem. Any idea whats going on?

 

Are you making sure to use Minecraft 1.12?

 

Yes

 

what is your ping?

 

Hey, I use an ethernet, too, and (sometimes) have the same problems. Have you tried also using wireless on top of ether? Also, it would help if you could use a site such as speedtest.net to test your connection with and without ethernet.
