Again, I repeat that I can't access the 6110 with or without the router between it and me. It will only connect my computer to the internet if i directly connect it to the computer. With the router in between I get NO internet connection either.
The 6110 is a modem. It should not have an ip address of 192.168.1.1. that typically is a router address.
You say you can't access the 6110 with/without the router between but that it will connect if you directly connect the 6110 to the computer. dslr & I are trying to help but we can't go much further without knowing your PC's assigned IP address.
What IP address is your PC getting when you connect to the 6110 without the router in the middle?
What IP address is your PC getting when you connect to the router?
