Cannot connect to certain website with Ethernet plugged in but can with wireless.

[ImPiff]

As I said, I cannot connect to any of my schools websites when i have an Ethernet cable plugged into the dorm but can connect to it when i am connected via wireless.

Is it just you or is it everyone in the school that can't connect?

It's possible the school has a firewall setup incorrectly that blocks access to locally hosted data when accessed on the Ethernet vlan.

We had that problem for a few hours when we purchased a new firewall appliance where I work.

I'm not sure if it's just me or not as most people here use laptops so they connect wirelessly. It hasn't been happening for only a few hours either, I was never able to connect when I plugged in my cable something like a week ago.

I'd call your school's I.T and see if they notice anything going on.

We actually didn't notice right away with our issue due to us using ethernet and wifi at the same time.

When the connection couldn't find it on Ethernet it switched to wifi instantly and showed the page.

But when we disconnected wifi it would not work.

We eventually fixed the issue by editing the rules on the firewall, but that would be a job for an I.T technician

If something hijacked your hosts file it would affect both ethernet and wifi, so it can't be that.

I can't see a virus blocking access to a single site on only 1 network connection.
If anything a virus/trojan would redirect your homepage to a different site, but that would be for all network connections, wifi and ethernet.

Make sure both your ethernet dns servers are set to automatic or at least the same as your wifi's dns servers.

I'll go ask the school's IT people before class at 2:00 if they noticed anything.

I checked and both are currently set to automatic.

So unsurprisingly the schools IT just directed me to https://uncw.teamdynamic.com/TDC which i had already gone to but it was useless as it had none of my problems. I fi go to this website however it gives me an error saying the dns addres could not be found.

First step is going to command prompt and typing

1. "ipconfig /flushdns"
2. "ipconfig /registerdns"
without the quotes

If that doesn't work then it's possible the Ethernet is automatically pulling the wrong dns servers, but the wireless is doing it correctly.

Unplug from Ethernet and with only the wireless connected go to cmd prompt and type ipconfig /all.

Copy down the dns servers you get.

Paste those dns servers into the Ethernet's dns server configuration.

I assume the latter part of this answer will work as my wireless connection has one dns server that is different than the ethernet. I would try to do what you said but i feel like i'd mess something up so I'll just deal with it for now. Thank you for the help.

If you mess it up just set it back to automatic.

I could set my dns server to all zeros and the only thing that would happen would be i wouldn't be able to navigate to other sites by name until I fixed it by either typing in a good dns server or choosing automatic and letting it pull the dns servers from my router (that I know has good dns settings lol)

I am having the same exact problem at our office not being able to view a series of storefront opencart 3.0.2 subdomains with a wildcard SSL from GoDaddy. We've contacted Comcast, GoDaddy and SonicWall where each has checked DNS info, traceroutes, blocked IPs, etc... I believe every possible scenario has been investigated and it still doesn't help. I am on a iMac OS running High Sierra; the only way I can view these wildcard subdomains is if I turn off my Ethernet network connection and connect through a wi-fi connection. Anyone outside of our network/IP can view these sites with no issues.
