So I moved into a relatives house in a different country and they only had an ethernet cable option for internet. Using it on their laptop, it works fine, nothing wrong. I try to connect it to mine, it comes up as an unidentified network or some random network number and shows the title error. Tried to reset the modem and do that ipconfig thing on cmd but no change. What is it that should be done?

System is Windows 8.1.
Not sure if there is anything else youd like to see.
 


It doesnt have wireless and only a single port so I assume its a modem. What would one have to do for those functions or IP?
 
On their laptop open up a command prompt (Windows key + S). In here, type "ipconfig" (without the quote marks).
Should tell you a bit of information such as the laptops IPv4 address along with the subnet mask and default gateway. Note down the:
SUBNET MASK
DEFAULT GATEWAY
IPv4 ADDRESS

My advice would be try setting a static IP address on your computer. Go into your network and sharing centre, find your network adapter and right click and go properties. Go down to "Internet Protocol Version 4 (TCP/IPv4)" and click properties again.
In here is where you can set a static IP address for your adapter. Because I don't know your internet situation, I'll try to use a generic one.
Here is where you enter the information you entered. The only difference is you put a different IPv4 address. Try something like "192.168.1.150". Click okay, exit out and even reset your adapter and see if you can access the internet.

If the other laptops IPv4 address did not start with 192.168.x.x, let me know.

Hope this helps
 


Sounds good, had trouble trying to get the default gateway though. The laptops ip address also doesnt start with those 192 numbers so maybe it should be different?

Woking laptops ipconfig:
IPv4 Address: 169.254.8.128
Subnet Mask: 255.255.0.0
Default Gateway: fe80: :212:e2ff:fe70:b2d4%11

Yeah I had no idea how to interpret that gateway...
 

That IP address points (169.254.xx.xx) is created bey Window, because it could not get an IP address from you modem. The default gateway looks address looks different, because it's an IPv6 address. At this point you need to call the Internet service provider for help. It's impossibel to figure out what the problem is, without the exact config of the ISP line.
