help Almost no internet connection.

[Jiro Niedeveld]

So I have an internet cable coming from downstairs to my room. My PC has the best Internet connection in the whole house (550 Mbps), but the rest of my family had wireless, and that was really slow for some reason. I came up with an idea to put the internet cable from directly downstairs in a router in my room where all the cables are plugged in to love the rest of the house good internet connection. The problem is that my PC says that it has connection, but it just doesn't load anything. 

Of course I tried replugging the cable on both sides. I tried putting it in an other slot. I tried plugging the cable from downstairs directly in my PC. I checked all sorts of stuff, but none of it worked. I think it's the network adapter on my motherboard (Gigabyte Aorus B450 ELITE).

Can someone pls help me?

Is your cable going from a router to another router?  This could be an issue of double-nat.  Open a command line (cmd.exe) and try doing a traceroute to google: tracert 8.8.8.8

 

Another possible issue is that the ethernet cable from 'downstairs' got damaged at some point.  You might be able to test this by using the 'ping' command on the command line.  Whatever your default gateway is for the 'downstairs' router, try a ping -n 50 192.168.** (whatever the IP is) and see if you drop any packets.  There should be 0 packet loss within your own network.

 

The best way to test a slow speed issue is to plug the computer directly to where the internet is coming from (example: directly to the router/modem)
