Could DirectTv server be causing my Double Nat Issues?

Could DirectTv server be causing my Double Nat Issues? I am using an older Motorola Modem, then my Airport Extreme, then my airport express in bridge mode. The DirectTv server seems to be plugged in before the Airportr Express so I am pretty sure it is no getting any info from the Airport Extreme but I am not sure.

The modem is model Motorola SurfBoard 5101U. I do not beleive it has router capabilities.

The problem seems to only come up when I am using my Mac Book Pro (Mavericks). Usually only when trying to download large files. It does not effect my ipads or iphones. Very strange.

I've been racking my brain on this for a year.

Thanks,

Stephen

Not sure what you mean by "server". If you are asking about your satellite receiver/DVR, this would not be causing a Double NAT issue.

Since you are using an older Docsis2 modem, and your provider is very likely using Docsis3 technology, it might be time to think about replacing the older modem with a Docsis3 model.

That may not solve your issue, but it would be the first thing that I would try.

Yeah, I've been meaning to replace that old modem.

What I mean by server is the Genie Media Server that Direct Tv uses to connect all the Genie minis in the home. I'm not completely sure, but it seems like the problems started when I had that installed.

Also, why would it only effect my Mac Book Pro, and usually only during large downloads?

I admit, I know a few things about a lot of things, but network jargon is something that always throws me for a loop.

Thanks for your input, Bob.

So, I run into some similar problems. I used to have the HD-DVR pre-Genie, which is when I started seeing some of the problems that my AirPort Utility was reporting. I hardwire every connection where possible. I currently run out of my AirPort TC into a switch. From the switch I go out to the rest of the house including an Apple TV and the new Genie. Along with multiple other wall ports, etc.

It seems to me that whenever I have my Genie hardwired in - for extended period of times my network will "crash" and I will receive an error of Double NAT. Once I unplug the DirecTV from the network, everything goes back to working fine. This ocurred on the old HD-DVR as well as the Genie.

I would welcome any ideas or suggestions.

I am running a Motorola SURFboard S86141, New AirPort Extreme TC, and a Netgear 8-Port Switch.

Thank you in advance for your help!!
