PACE 11.1.0.531418 DMZ Issue

Oh, the most annoying issue after losing the ability to use Chromecast is this latest update is causing my Google WiFi access points to randomly go offline. Thanks AT&T O_o

@Swerved, as @n2itus just said, they upgraded firmware for both of us 2 times in 2 days.  I'm going to downgrade again but expect the worst. 

Seems like the only "fixes" are going to be:

1.  Downgrade firmware every single time

2.  Live with manually forwarding all TCP and UDP ports and the shenanigans with that

3.  Pray that you get someone to send you a different modem

how can I downgrade the modem firmware? can somone post the firmware here?

The replacement BGW210 is no picnic either. For those that use site to site VPNs it has stability issues with those too. After a week or so it starts randomly dropping some of the tunnels. I've disabled every possible "feature" of the router. 

ATT needs to take a lesson from the competition and allow folks to manage their own edge devices easily. Their repeated use of band aids on top of ancient hardware on an otherwise reliable service just does not make sense to me. The phone tech support can only ever offer a "line test", "reboot", "connect directly to the modem to test", or get a tech with a varying level of experience to come out and swap modems. When I went through this last time, the phone tech had absolutely no clue what I was even talking about when I described symptoms. The onsite tech had no experience using DMZ+/Passthrough Mode other then to point me at a webpage and state that its the most often heard complaint are problems related to this feature in "advanced" home/home office setups.

The firmware is earlier in this thread but I know it's a long thread.

tonydi graciously posted it in the thread I created:

you need to go to your router's page and go to the hidden /upgrade path and upload that file.  All the lights on your modem will turn off at some point and it will take much longer than you're comfortable waiting the first time but it should complete.

Downloads via DMZplus and my Asus router had throttled to 50 Mbps again and sure enough the Pace had been updated to 11.3.1.532191.

Out of frustration, I chose to Factory Reset using the red button on the Pace this morning.  After that finished, I reconfigured DMZplus.   Now, I observe full speed downloads. I was surprised. 

@atlr 

Is that a screenshot of your system after the factory reset or before?  Do you still have 11.3 firmware?

That screenshot was after a factory reset. It was a pushed update so I do not have a file.  

Hmm, so DMZplus works with the new firmware?  Did you reboot your internal router to pick up the IP correctly?  Earlier today I thought I had it working with the new firmware but it was because it still had an internal IP address from the PACE and wasn't really in DMZ mode. 

I said it in the other thread but now the firmware updates almost immediately after I downgrade, so that's no longer an option.

Has there been any indication from an employee or anyone else that this is even recognized as a problem that they're trying to fix?  I called in today and asked how I can log a bug ticket or something and they said I did all I could posting here.  But I haven't really seen any official response to either my thread or this thread, besides manually forwarding all ports and not using DMZPlus.  Maybe I missed it in this long thread though.
