I will try those tests when I get home this evening and post the results.  I can tell you that I can access the routers setup pages and go to any page within them, but I cant reach external websites. As to can I ping the gateway or the DNS I will have to try that later.

thx

When this happens can you ping the following?

1) the routers IP
2) the routers gateway ip
3) 4.2.2.2
4) google.com

Let me know where that fails.


Wouldn't it be helpful to also try to ping from the router?

It can't hurt. But if the PC can ping the router then it shouldn't matter.

OK I ran the tests after making the modem lose connection. I was not able to ping 4.2.2.2, my gateway IP or Google.

Hi,

I have my VoIP box in between my router and my cable modem.  Inside the VoIP box settings I set up a DMZ for the 655-router's reserved IP as handed out by the VoIP box.  Inside the 655-Router setup I set it as STATIC IP using the IP from the VoIP box.

In this manner, I "believe" I avoid a double-NAT issue that some places say is a performance killing thing; not that I have seen it kill any performance either way.

If the WAN of your DIR-655 has a different IP than what you get when you visit http://whatismyip.com (a private IP on your DIR's WAN is a dead give away) then your double NAT'ed, it is that simple.  Private IPs start with 10.x.x.x, 127.x.x.x, 172.16.x.x, 168.254.x.x or 192.168.x.x.

Double NAT'ing does not kill performance (other than adding a little latency so your traffic can be NAT'ed twice), it potentially kills specific types of traffic, and if configured wrong potentially all traffic.  The biggest reason we preach against it though is it makes troubleshooting neigh impossible.

The real reason I am here though is to say it looks like your wandering off topic, you might try starting a new thread, or explaining the connection so that your problem gets the attention it deserves.

What are the IP's listed in the routers WAN page when it's working?

The IPs listed are my ISP gateway and my external IP as given to me by my ISP. They dont change when it does not work either. The routers status page looks like nothing has happened, but in reality the router in no longer passing data.

A little extra info.  My external IP is DHCP assigned, but it never changes. It is locked to my MAC address. So each time the router reboots or the modem reboots I always get the same IP, month after month after month. So after I reboot the router the status page looks just like it did before it locked up, only the up time counter resets back to 0 hours.  And yes the up time counter is continuing to count forward during the entire time that no data is passing. So in that respect the router thinks its still online.  But if I do a release and renew IP on the router it comes back to life. Its almost like the router does not accept getting the same IP address from my ISP unless it is forced to.

I would post screen shots if I could, but the forum does not seem to allow that.
