Hey, I recentlt bought an Ariis router for my home needs. I use a Comcast internet connection as service provider. When I sat down to configure my Arris router, the IP address part seems to have issues. I googled my IP and DNS but when I put them in their respective place nothing happened. I mean the Router could not connect to internet and asked me to look into my WAN settings. Can anyone tell me what the issue is? I use a Windows 7 PC.
