Hi all,

Does anyone here have this set up?

VF Cable: Cisco DPC3008 >>>>>> Netgear R7000

Since friday I've been trying to get these to work, the issue being I'm not getting any internet connection.

Have used the same Static IP details as for my previous router (VF supplied Netcomm NF5). The LED on the front which indicates if the Internet is working comes on as soon as I save the IP details yet it says No Internet on the routers menu.

Running latest firmware.

Have tried factory resets for both cable modem and the router already. Have also tried MAC spoofing.

What am I doing wrong?

Thanks

covering the basics here when u replicated the static ip info that included Gateway, Subnet, DNS.?

if that all fails, try putting the orignal netcomm back and have the internet back working, then connect the wan port of the r7000 to the netcomm and set it up with local ip info from the netcomm and then see if it complains about no internet, this will prove if its a faulty router or bad ip configuration.

other thing to note maybe power cycle the Cisco once you have set the new ip config in the nighthawk, just in case its caching the mac address

For probably a good 8 years there was a limit of 1 MAC address that could be bridged behind a cable modem and this was cached every 10 or so minutes. It means if you ever swapped a router you'd have to wait for this to clear before a new router would work.

This was changed a few years ago to remove this limitation, but I wonder if it's now back?

I've just tried the Netcomm: Same as the Netgear (Internet LED on but no internet)

Have also tried a Linksys E1200 and a 4th Gen Apple Extreme Base Station with the same result. I wonder if something has gone wrong at VF's end when I reset the cable modem?

I've gone into the DPC3008 menu and everything seems in order as far as I can tell.

to be honest ive never found a need to default the DPC3008, i would set up everything on the R7000 and then double check the correct gateway,subnet,dns, and then turn off the DPC3008 and the r7000 and go make a coffee, and come back and re-power the units.

Did you take a screen shot of said ip info before starting all this? (Im just trying to confirm you wrote it all down or screen captured it all)

Thanks for the replies.

I've been over to my parents who have VF cable also with a 3008. The R7000 works fine there.

The Static IP screenshot is the same one I took the day the cable install took place back in 2014. I tried turning the DPC3008 off for one hour before (including the Netgear) but no change.

I should also state that the Netcomm still has the Static IP details saved but it still didn't work.

The next thing I'm going to try is connecting a laptop directy to the Cisco. If that dosn't work I'll guess i'll be calling VF.

I'm finally posting via the R7000.

I connected my laptop to the Cisco modem, added the TCP/IP 4 Static IP details but I still couldn't connect. Then I noticed that Chrome would give me the error "DNS_PROBE_FINISHED_BAD_CONFIG"

I changed the DNS settings to the Google DNS servers. Not really a solution but at least my network is back online.

Any ideas as to why VF's own DNS servers are not working via the Cisco?
