Hey tellto. I also have AT&T Uverse Gigabit, and for the life of me I cannot get my Netduma to get over 75 down, and 75 up. On average, it's closer to 50. I pay for 1000, and I'm scratching my head over here.
I've followed this guide for setting my gateway in DMZ/Passthrough or DHCPS-Fixed mode via a WAN IP from and the Mac address on my Duma. I've followed several "optimization" tips and guides I've come across on this forum. Reactive algorithm enabled. Disabled CC by ticking Turbo and Super Turbo on. Disabled WAN and LAN IPv6, and misc. Reset device prioritization. Yes my gateway and Duma have been rebooted. Yes the ethernet cables I have can handle my speeds. You name it, I've likely tried it folks.
Funny thing is, when I got the Duma I tried just plugging it into my router (not ideal) and it would max at 500/500. Nothing more, nothing less. So I KNOW it can be faster than it should be. This isn't due to a recent outage. My line isn't faulty. If I unplug my Duma and reset my AT&T gateway to default right now, I'd be getting over 900 down and up no problem. Issue seems to either be user error, or on the Duma's end. And I'll take 100% full credit if it's me folks. But sheesh, I try setting the thing up the correct way and I get less than 1/10 the speed I pay for. ¯\_(ツ)_/¯
If anyone would love to toss a guy some helpful advice, please reply to this thread or hmu on Discord ---> https://godlik.es/discord
