Speed issues with PACE 5268AC DMZ+ mode

Speed issues with PACE 5268AC DMZ+ mode

I've had my RG, PACE 5268AC, configured with DMZ+ enable on my Ubiquiti Edgerouter for a long time now and had no speed issues.  Recently I've discovered my download and upload speeds are greatly reduced now.  Before I would get near perfect 900mbps symmetrical speeds now my download is capping at ~40mbps and upload at ~100mbps.  When I disable DMZ+ for the Edgerouter my speeds return to near normal 900mbps.  If I directly connect a computer to the RG and configure that computer for DMZ+ the speeds for that computer are identical to what I'm seeing with Edgerouter.  That being 40mbps/100mbps download/upload if configured for DMZ+ and 900mbps symmetrical.  Is the RG going bad or has a firmware been pushed out to the PACE 5268AC that broke DMZ+.

 

I guess should I ask for a non-PACE RG or is there a solution to restore DMZ+ back to it's original functionality?

Re: Speed issues with PACE 5268AC DMZ+ mode

@ATTDmitriyCM, I've seen this same observation over and over.  Can we get some feed back from engineering as to why this is occurring and/or whether this is something we need to alter on the third party router or if this is an issue in the firmware that can be corrected.  Or at the very least make sure engineering is aware?

I have the same issue.. removing from DMZPlus for short term fix but double NAT is not good because I use the google wifi mesh behind the router.

Re: Speed issues with PACE 5268AC DMZ+ mode

I’m having the exact same issue with my Pace 5268 since the firmware was updated to 11.1.0.531418 about 2 weeks ago.  I just had an ATT tech to my house to swap the RG for a new one of the same model, but with older firmware and full speeds on DMZ+ was instantly restored.  Now I’m afraid the newer bad firmware will be pushed again and I’ll be back to the throttled speeds.

Re: Speed issues with PACE 5268AC DMZ+ mode

I should throw out a "me too." Dmzplus is suddenly 50Mbps down and anywhere from 90Mbps to 190Mbps up, vs anything not dmzplus is 700Mbps down and 980Mbps up.

 

Any updates on this? I don't want to hassle with equipment replacement out of the same concerns as voiced by @Firmware

Re: Speed issues with PACE 5268AC DMZ+ mode

I had my issue resolved by having the RG replaced and when AT&T was arranging the replacement I asked specifically to have the Arris NVG-599 sent instead of the PACE 5268AC.  Once I replaced the RG and used the Arris's ip passthrough it worked like a charm.  I know one person got a PACE replacement with the older firmware but I would also worry that the bad firmware would eventually get pushed back to the 5268AC.

Re: Speed issues with PACE 5268AC DMZ+ mode

I was battling this Pace V11 firmware screw up since 11/29 when I first noticed the 50Mbps throttle. This thread has quite a bit of info: "PACE 11.1.0.531418 DMZ Issue". That said, it seems that AT&T is VERY slow to react, their field techs don't seem to know about it or have only just heard "something" about it. If you speak with phone support and tell them about the Ver 11 mess, you get asked if you did a hard reboot. If you order a replacement with a PROMISE not to ship a PACE RG; 99.9999% probability you will still get a PACE! That happened to me. (If you install a PACE with the old v10.7 it will just update to V11 again) I eventually had a Tech scheduled and when he called prior to arriving, he only had PACE RG's in his truck. A check of all the Techs in is group was the same, they all had PACE RG's. He managed to find a Manager with a BGW210 and he graciously met and took possession of said RG. So on 12/15, after the BGW210 installation, my speeds are back to what I am paying for, 1Gig. It seems the only way to get a non PACE RG is by a visit from a Tech. I will be requesting a refund for degraded service.

Re: Speed issues with PACE 5268AC DMZ+ mode

Me too

I've called twice now to have my PACE RG replaced. Same as above, over and over they promise to NOT send the PACE. Twice now I received the PACE.
You can do NOTHING about this. My guess is this has nothing to do with the phone reps but the warehouse sending them out. Don't take your anger out on them.
When I asked for a technician to come out they said it would cost me $99. Really?

I guess I could just keep calling every few days to have another modem sent out until I get the right one. Only problem is I have to keep dropping them off at UPS to send back. Maybe I can work something out with the driver when he drops off the new box I give him the last box he dropped off. 

 

This is such a PITButt I might just switch back to Spectrum. Same speeds, same price and a local office I can pick up equipment when it needs to be replaced. 

I'm also amazed at how this posting system checks for profanity in my post before allowing me to post. Seems they have that part down, now maybe fix the stuff causing us to use profanity.

That $99.00 thing is a standard reply to a Tech request. They have to say it. Do not worry, they KNOW now they have a full blown problem. Put in a request for a Tech, make sure to have them note on the ticket the Tech MUST call before coming then when he does ask if he has ANYTHING other than a PACE. If he does not, ask if he could check his group for a BGW210 or NVG299 (I prefer the BGW210) and if he would mind picking it up. My Tech did that and so have others. Go to the following thread and read a few pages, please. So far, almost everyone has had success with a Tech bringing a BGW210 or NVG299.  Since you are having problems with the PACE in DMZ+ you probably have your own router and are NOT using the RG in standalone mode. Having said that, I will caution you, the BGW210 with current FW v.1.7.17 is having reboot issues when used in the Default Standalone mode with WiFi on. However, it works perfectly fine in Passthrough Configuration with WiFi Off! (I have mine so configured). Here's the forum I mentioned (also IGNORE the "Solved" title, it is not) One more thing, if the Tech is a noob, show him the forum: https://forums.att.com/t5/AT-T-Fiber-Equipment/PACE-11-1-0-531418-DMZ-Issue/m-p/5764334#M8314

Good Luck.

Re: Speed issues with PACE 5268AC DMZ+ mode

@TreborTek - What they had said is "If the issue is found to be an issue not with the Uverse network or equipment there will be a $99 fee, but the technician will discus it with you prior to being charged" (slightly paraphrased, but close enough)

All it means is that if the issue is something that AT&T had nothing to do with (In home wiring, an issue with your own devices, something that could be done without a tech such as moving a STB, also moving the position of the RG I believe as well) it would cost $99 for the tech to work on the issue. Since the issue is with the RG itself, it shouldn't actually apply, although I don't know the specifics of your situation, so I can't say for certain.

That bit of scripting is something they are absolutely required to say before setting up a dispatch, in all circumstances, they're not saying it will cost that much, but that it may cost that much.

The dispatch is going to be your best option for getting a BGW210 out there, the agents can try to get the system to send out a BGW210, but in the end, what model that is sent out is determined by an automated system based on many factors.

Just found this thread and I’ll add a me too with the DMZ+ issues.

Re: Speed issues with PACE 5268AC DMZ+ mode

Mine is fixed now. Here is the long and short of it.

 

1. You need to get a service tech to come out (as others have said). Tech said the warehouse will send like for like so even if the agent says send BGW210 you will only get it if you already have a BGW210.

 

2. Once you get the BGW210 you need to setup ip passthrough for your router. Don't use cascade router or any other setting. Lots of bad suggestions on these forums.

 

NOTE: Make sure your internal network (your personal router) is set to something other then 192.168.1.x. It make this process much easier.

 

3. Reboot the BGW210 after you set ip passthrough, otherwise the setting doesn't fully take. After the reboot only your selected device (in this case your router behind the BGW210) will work when plugged into the BGW210.

 

If you don't need to access your home network from outside the house you should be done here. Make sure your home router is set to get a DHCP address from the BGW210 an you're good to go.


If you need to access your router from external you WILL NEED TO SETUP THE FORWARDING RULES on the BGW210. Very strange since that is what I expected with the ip passthrough but that's not the case.

 

4. On your internal network you can still get to the BGW210 management page on the 192.168.1.x network. Open a browser and go to 192.168.1.254.

 

5. Click on Firewall -> NAT/Gaming -> Custom Services and add the following

 

Service Name:  Stage0

Global Port Range:  1-21

Base Host Port: <blank>

Protocol: TCP/UDP

 

Service Name:  Stage1

Global Port Range:  23-7546

Base Host Port: <blank>

Protocol: TCP/UDP

 

Service Name:  Stage2

Global Port Range:  7548-51000

Base Host Port: <blank>

Protocol: TCP/UDP

 

Service Name:  Stage3

Global Port Range:  51025-61000

Base Host Port: <blank>

Protocol: TCP/UDP

 

Service Name:  Stage4

Global Port Range:  61002-65535

Base Host Port: <blank>

Protocol: TCP/UDP

 

 

6. Go back to NAT/Gaming and add Stage0-4 to your router from the dropdown menu.

 

NOTE: Whatever IP Address is set here make sure you set your router to this as a static IP for the WAN port.

 

You should be good to go at this point. If you need any ports in the range not listed above you are out of luck. All those ports are reserved by ATT. Just work around it.

 

At this point your internal router will need to have the firewall modified to allow any traffic through you need. If your speed still isn't where it needs to be make sure any modifications you made during troubleshooting are reversed. I had a hardware offloading setting on my personal router that was still limiting my speed. Put that back to original setting and now I'm rocking. 

 

 

Hope this helps.

Re: Speed issues with PACE 5268AC DMZ+ mode

If anyone follows TaborTek's advice successfully, please post.  I"m especially interested in anything that is fixed (i.e. didn't work before and works afterwards) by setting up the port forwarding to a device when IP Passthrough is enabled to that same device.
