AT&T U-verse → Re: DLink DGL-4500 Behind 2Wire HGV-3600 (in DMZ) Disconnection

This sounds like you might know the problem but might be looking at the wrong thing. If your dlink router reboots randomly, then I have to question if the router is actually performing like it should.

I assume you setup your 2wire modem to have the dlink router in DMZ+ mode?

What happens if you were to do the following next time your dlink reboots or has connection issues: plug yourself into the 2wire modem bypassing the dlink. Do you still have connectivity to the internet? If so I would say you might have a hardware issue rather than software. If not then you need to persue a different problem

Also can you get to the dlink router status page and see if it has appropriate IP info from the 2wire modem when you have a issue?

bdavenport, thanks for the reply.

Like I mentioned in my original post, prior to switching to UVerse service, I was only using an ATT DSL modem and my DGL-4500 router worked flawelssly.

Since I connected the 2Wire router / gateway last 08/10/2012, I have been getting these reboots.

I honestly don't think the router is broken and I think the reboots are due to the new configuration.

I wish there was a way ATT can send just a UVerse modem (NOT a router / gateway), but, unfortunately, there's nothing I can do about that.

As of this morning (before heading out to work), I checked the DGL-4500 and it says it's been up and running for 1 day and 16 hours, so, it's been up for quite sometime now since last Sunday's reboot.

Hopefully it stays that way.

I'll keep you posted.
