I built a new computer with an MSI Z97-G45 mobo, installed Windows 8.1 and all of the drivers to go along with the new hardware. Then i ran into a problem with the Ethernet adapter and spent quite a while trying to connect to the internet. It would connect to the network but would show no internet connection. I plugged the Ethernet cable into my laptop and it worked fine, so it had to be a problem with my new system

I tried everything i could find in the forums, from new drivers for this (apparently crappy) Killer E2200 network adapter to fiddling with the registry and ip addresses, but to no avail.

I connected my laptop back to the Ethernet cable and compared the ipconfig values with the new system. They were completely different so I manually assigned my laptop's IP and DNS values to the new system and now i have an internet connection.

I know that I should obtain the IPv4 and DNS addresses automatically, but I still couldn't get an internet connection even when i renewed the IPv4 adresses. Why would these addresses be different on two different computers connected with the same cable. Do you all have any recommendations to fix this where i obtain the addresses automatically? Does it even matter if I obtain the addresses automatically?

Disclaimer: I'm fairly new to this so i welcome the criticism of my computer tech overlords.

I cannot understand that. One address (the 10.x address) is a private address and the other address (12.x) is a public address. The only thing that I can think is they give each apartment one public IP address. If you want to use more than one device you need to put a router in. It looks like they may record the MAC address so that only that address can have the public IP Address. Not really sure though, very strange. Maybe someone else on this forum can help better than me on this issue.

I was talking to the owner a few months ago about a problem he was having with people connecting their own wireless routers rather than using the wireless signals from the routers he had placed in certain rooms of the apartment complex. He said the "unauthorized routers" were messing with the ones he placed in the certain rooms. So he did some stuff (called a guy to come fix it) and now you cant hook up your own wireless router.

I just don't see why my old desktop PC connection was fine and my laptop connection is fine, but this new system is giving me problems. I still think its an issue with this burger flippin' mother board/Ethernet adapter.

Thanks for taking a stab at it abailey.
