Please try to see if you can ping 18.104.22.168 or 22.214.171.124, which are public DNS servers, in command prompt as I would like to know if you are having a DNS issue or you do not have internet. On the RVS4000, what IP address do you get as your WAN IP address? Also, does your new modem have 1 or 4 ethernet ports on the back of the unit or what is the model of your modem? This should allow us to further troubleshoot the root cause.
When I ping the public servers while using the Linksys RVS4000 4-Port Gigabit Security Router attached to the Surboard cable modem it returns a "Reply from 192.168.1.1: Destination net unreachable".
No WAN IP address appears in this property, the LAN IP shows as 192.168.1.1, as it should, right?
The cable modem is a Motorola Surfboard model SB6183 and it has only one Ethernet port, which is connected with Ethernet cable into the "Internet" port of the router.
I found an old wireless router (Linksys WRT610N) which I installed and it is working fine. I have connected a switch to it and three different pc's and they are all connecting to the internet. It shows an "Internet IP Address of 126.96.36.199, Default Gateway is 188.8.131.52 and the DNS1 is 184.108.40.206 and the DNS2 is 220.127.116.11.
What's even more confusing is the RVS4000 has worked fine when it was behind the Verizon DSL modem, and that has been for a few years at least?
Thanks again for looking into my issue. I attached a Word doc with screen shots.
In order for the internet to work, you will need a WAN IP address on the router. What is the LAN IP address of your Motorola Surfboard? If the IP address is 192.168.1.x then you need to change the RVS4000 LAN IP address to be 192.168.x.1 where X is not equal to 1. If both devices are on different IP addresses then try the following steps:
1. Plug a PC into the modem and make sure that you get internet and able to get to multiple web sites
2. Plug the RVS4000 back into the modem and then plug the PC, that you were just able to get internet with, into the RVS4000 in any of the LAN ports
3. Log into the RVS4000 and go to MAC address clone and there should be an option to clone the MAC address of your PC
4.Verify if you do get a WAN IP address and if you do, you should get internet at this point
You can manually change the MAC address in the RVS4000 settings. Also, please make sure that the Clone MAC address is enabled as I can see it is showing as "disabled" from the screenshot. The clone MAC address should have been the MAC address of your PC. You can verify the MAC address of your PC in the router if you go into command prompt on your PC then type in "ipconfig /all" and you should see your MAC address under "Ethernet adapter Local Area Connection" and it should be "Physical Address."
