C6300BD DHCP Issue

Greetings all,

 

I hope you guys can help. I have spent HOURS with my provider's 'Tech support' people.

 

Here is the problem: I have several computers and phones in the house that are experiencing the same problem. The problem is that when a computer boots up, it is not issued an IP address (Yes, that is enabled on the router). The only way to get internet connection is to either reboot the router or setup a static IP. Once I reboot the router, it works for a few hours then decides it does not want to play DHCP any more.

 

I have conducted a factory reset of this modem and have had it replaced. Both units did exactly the same thing. At first I thought the problem was configuration, so I started over after a factory reset. The changes I make are trivial. I merely rename the SSID and set a password. Nothing else is modified. Then I was thinking that perhaps its a specific computer, but three different laptops, one desktop, four iphones, and one wireless printer experience the same issues. There is no way all these computers have the same issue.

 

My theory is based on the commonality here. Its probably not the hardware, since I replaced the box, and hardware does not manage DHCP. That leaves the firmware in the box.

 

Someone please help!

      I think its the service provider.  its seems that Comcast has started using the IPV6 setup, and all  of a sudden two days ago, none of my wireless devices could connect to the Internet, although they stipulated they were connect to the Netgear, both 5 g and the 2.4 g setups.  I changed the wireless channels thinking my neighbor was confusing my devices, but that did not help.  My devices, several laptops, serveral iPads, iPhone.  all started displaying the IP address of 169.254.62.xxx which is not the wireless address quad I setup in the router, i used the standard 192.168.0.xxx.  So in order to get things communicating again, I used a static IP address in each device, and now they are able to connect and roam the internet.  I have rebooted the modem/router and had Comcast download the latest firmware but nothing has changed.  I firmely belive it is something Comcast did when the enjoined the IPV6 protocol.  Not sure how to get this fixed yet.  My printers and Dish network, Hopper & Joeys, PS3 and Blue ray still cannot connect.  How can I turn off the IPV6 ?

        Hello Beercan1951

        I do not believe you can disable IPV6 you may want to contact the ISP and check if they can change it to IPV4 address.

    Go to Advanced settings in your internet connection to disable IPV6. Works on my PC.
