IPv4 issues after SB8200 upgrade.
After upgrading to SB8200, my router and modem have issues with IPv4 adresses. It begins after a period of time. Restarting the router fixes it for an indefinite period of time but eventually it loses the ability to resolve IPv4 addresses. I have tried two different routers with the SB8200, with both routers experiencing the loss of IPv4 and have not had a problem with the SB6140. This started after an upgrade to ultimate. Other forums have resolved this as a ?backend" network engineering issue but the fix is not automated. I have tried disabling IPv6 and that does not work. When IPv4 shutsdown, access to the modem address, 192.168.100.1, is affected and the modem cannot be accessed. This is not a new problem but appears unresolved in Cox as a search shows this comes up quite often. I will need to cancel the service and return the modem if this is not fixed.
