Modem/router troubles

Hello,

I was having some problems with my internet connection last night so I went to my router (it's a Belkin N Wireless Router) and tried to a simple it but I think I accidentally reset it to factory settings. When I tried to turn it back on, it would not connect to my modem at all.

So I started thinking it was a modem problem, and I plugged the modem's Ethernet cable directly into my laptop to see if I could access the internet that way, but it just says "Unidentified Network / No Network Access" when I hover over the icon in the bottom right. All the lights on the modem are on, suggesting that it's connected and online. My laptop is a Lenovo Ideapad P500 running Windows 10.

I've been looking around for help on various forums and tried some troubleshooting but haven't had any success. Someone please help!
