I'm having an interesting experience with the AT&T gigabit internet I got recently. I have the Pace 5268AC router.
I need more features that that router offers so I'm putting a Netgear R7800 behind it.
Everything is great at first. I get over 800Mbs for a couple of days. Then, suddenly it's 50Mbs. If I plug a computer directly into the Pace I get 950Mbs. So, it must be the Netgear router that's the problem, right? I change the router and sure enough I'm back to 800Mbs.
Two days later I'm back to 50Mbs. Hmm. I try changing the MAC address of the Netgear router and I'm back to 800Mbs!
So the Pace is throttling me to 50Mbs based on the MAC address.
I should add that the 800Mbs goes away instantly when I go into DMZ+ plus mode. That puts me back to 50Mbs.
Further experimenting shows something even more interesting. The throttling seems to be at the switch level - not WAN to LAN in the Pace. That is, if I plug another computer into the Pace and run iperf between this computer and the Netgear I still get a low speed (although it did go up to 100Mps). Perhaps the Pace someone internally sets to port the 100Base T. Having said that, the Pace web page claims its 1000 Base T.
Hopefully this Pace modem is broken in some bizarre way. I'll try to get AT&T to switch it.
Anyone have similar problems?

I had the same issue trying to get a pfsense box up and running. Exact same thing happens when using DMZ+. This gateway is garbage. I have had 2 request for the BGW210 through the online chat. They have assured me they will ship out the BGW210 but according to the shipment info on both they are sending me more freaking 5268AC’s that I cannot use. Total pile of crap

I've been experimenting further and now the Pace modem has settled down to something more consistent.
In DMZ+ mode I'm throttled to 50Mps.
When I'm not in DMZ+ mode, I'm not throttled.
So the question is, does AT&T have this throttling policy, or is the Pace modem broken?

This happened to my Pace 5268AC also. I noticed it right after a Modem firmware update on 11/29/18. I thought it was my old Linksys 1900AC gone bad so I upgraded to an Edge Router with a UAP-AVC-M access point. It was wicked fast until I noticed that the AT&T modem firewall was blocking external access. Immediately upon Opening the Firewall and setting DMZ+, I was back to 50Mbps! I tested everything, Cables, Switch, everything. I'm now sure AT&T is throttling!!!!

I posted the following in a different thread "PACE 188.8.131.521418 DMZ Issue" and I am posting it here also because essentially the threads are the same:
I've been dealing with AT&T now for a few days trying to get my Modem back to 1Gbps that I am paying for. It seems that AT&T keeps track of how many times you call for an issue because when I call now I get passed from the "basic technician" to an "expert technician" without having to go through the "did you restart the modem" crap. Anyhow, a timeline follows:
The moral of this story is that the "solution" above, though well intended, does not fix the problem and it can ONLY be fixed by a visit from an AT&T technician bearing anything other than a PACE 5268!
