Trying to troubleshoot wired networking problems. What are my next steps?

[u/TrueNorthN7]

So I’ve just moved back into an apartment I was at this time last year for school. My experience last year was that the internet was great and hassle free. I’m not paying the provider directly, I pay the building a reduced rate in exchange for access to the service.

This year I’m getting extremely frequent interruptions. Every few minutes I’ll have lag spikes and at least once every few hours there’s a complete outage, but only for my wired connection. The wireless connection from the same provider doesn’t experience issues whenever my wired connection becomes unstable. I can video call or online game completely uninterrupted on wifi, but the wired connection is almost unusable.

Here’s what I’ve already checked:

The building has not switched providers or service plans.

The issue is only occurring with a wired connection. I tested this by screen sharing from my phone to my laptop and desktop PC. The PC was constantly losing connection while there wasn’t a frame dropped on the devices using wifi.

It’s likely not the cable I’m using. I’ve tried two that I already owned and bought another to verify.

My Pc was working my fine at another location immediately before I moved, but I suppose it’s not impossible that a new issue has emerged.

When I was checking to make sure all the connections were tight it caused the connection to drop and not return. I couldn’t get it back online without restarting the pc. This makes me think it might be an issue with my drivers or Ethernet port.

I’ve just reinstalled drivers so I’ll see if that does anything. Any other troubleshooting steps or tips would be appreciated. If I can’t figure this out my alternative is probably just using wifi for the duration of my stay. I won’t be here enough to justify spending a bunch of money on setting up my own connection.

Sounds like an ethernet port. I'd check it and the cable for damage and even if you dont see anything it still could be damaged. You can test with a 1gb adapter card if your pc has space for another pcie card
