Re: Router loosing IPv4 connectivity

I am having a similar issue to a hotspot that I frequently connects to. All of a sudden it's only providing IPv6 (no IPv4). Can this be a similar problem?

Hey batrad,


I would like to check the provisioning of your modem. Can you please verify your first and last name and the phone number associated with your services?

This is not the same issue as the provisioing issue where the user used the WAN-MAC and not the HFC-MAC (CM-MAC)..  If I took a guess I would say your CPE device is showing up in the system as a DOCSIS device and not a CPE device..  The modem will need to be  re-provision all together if this is the issue via a tech support or someone in the provisioning system would need to check your WAN-MAC and make sure it is a CPE device..

What is the IPv6 CPE address your getting?  That would tell me right away..

Router loosing IPv4 connectivity

Every 8-10 hours our router keeps loosing IPv4 DHCP/DNS Settings and i only have an IPv6 address/DNS on my devices and we are unable to browse to the interenet except reach and whats my IP confirms i only have a IPv6 address


I have tried increading my DHCP scope to over 200 devices (we have about 50 devices connected to our home between the TV's, Computers and Mobile devices, changing the router and still have this issue every day and the the only fix is to reboot the router. I turned off most of my devices, leaving about 10 devices on (phones and DVR) and still get an error twice a day for connectivity


Swapped the router from Netgear to Linksys and the issue is still there.


If i set a static IPv4 address on my Laptop, that continues to work while all the other devices that get a DHCP IP fail to connect till we reboot the router


The issue started about 4 weeks ago and its been driving us nuts


Appreciate if anyone has suggestions on how to fix this issue
