There was recently a storm with a full power outage and my roommates and I all lost power for 24 hours. When power return both my roommate and I's PCs would not properly connect the internet via ethernet and only could connect via wifi. The error shows DNS errors. I have been trying to fix the issue for 9 hours now any help would be greatly appreciated!

That makes no sense at all.

However, you could try to set the DNS manually to 8.8.8.8 and 8.8.4.4 respectively. Those are Google's DNS servers.

I'm guessing that Morten means that the likelihood that this is actually a DNS issue makes no sense, and I agree with that.

Sounds like what got fried by the surge that usually accompanies a power outage or reestablishment is the router's ethernet switch, at least two of the router's LAN ports, multiple ethernet cables, and/or the computers' ethernet ports. My money is on the latter, but troubleshooting will be necessary.

You are correct Terry. That's what I meant. Since the router probably hands the same DNS addresses - via DHCP - to both wired and wireless, it makes no sense that one will work and not the other.

So after troubleshooting and resetting router, the ethernet will work for roughly 5 minutes and they stop working again any ideas on why that would be?

I did several steps of troubleshooting and nothing worked still only have wifi but no ethernet connection. When My Ethernet port is plugged into other devices like my ps4 or my girlfriend's laptop it works just fine. Thoughts?

That alone probably makes me lean towards the router's ethernet switch being at fault, but you made another post ....

That (at least temporarily) removes the router's ethernet switch from the suspect list.

You haven't said enough about your troubleshooting of the cables or LAN ports for me to say any more.

Was the computers plugged into the router at the time of the power outage?
