|You need to look at a working model. It will have a way to show the network settings either from command line or from a menu type setting. |
If some person can connect at your home then we can assume that the settings they have are correct. We can also assume yours are wrong.
Unless your router has blocked your computer it almost boils down to dns ip address.
You say you can get connected? Then we need to get from your router to the internet. That generally involves two things.
One is a correct IP address, subnet mask and correct gateway address. That is what you need from the other computer.
Second is a way to convert FQDN or domain names like computing.net to an ip. that is done by an IP number that your ISP offers or simply use the router's IP address. Most modern routers will allow dns to be sent through it if it was set up.
Dunno why you rest some other router.
Hang up and live.
