Slow upload speed
Recently (last 2 weeks) my upload speed has slowed from around 20 MB to less than 10 (usually 7). I don't know why/how this change occurred since I have made no changes to our service. We have the 100 MB speed service. Our VOIP service has also been terrible, with calls being dropped or complete static. Looking for answers....

Sorry, this is not about optimizing my speed. This is about a change that occurred in the last couple of weeks. Prior to that my speed was perfect for my plan. Without any changes on our end, our download speed stayed where it was, but the upload speed was cut in half. I'm told by AT&T support that my modem is not communicating correctly with the service line and I need a new modem. I was promised an NVG599 modem but when the order was placed it was for the Pace 5268AC (which is the model I currently have). Order was canceled immediately but was shipped anyway. A service call has been set for what should be the new modem (?).
Something changed, but I can't identify what and my interactions so far with AT&T technical support have not been encouraging.

@mgbhouse The nvg599 is an older model. Probably none left in the system to ship. It sounds like your profile got dropped to 10 mb or one of your lines isn’t working right. Have the tech look at your line stats and inside house wiring to the gateway.

Thanks for your suggestions. Nothing has changed on the inside wiring. The gateway goes directly outside to the service line. They sent me a new Pace 5268AC with the latest firmware which I can't use because we run a router behind the gateway and when using DMZ+ it reduces our download speed to half (around 50 Mbps) of what we are supposed to get. I'm running the same gateway now with the older firmware and our downloads are 95-97 Mbps and we used to get 20 Mbps upload until very recently.

HI @mgbhouse,
In this webpage, you will find many solutions that have plagued your internet experience. Best of all, these solutions and recommendations were written by people of the internet! Please check you internet speed without the router behind your gateway.

Thank you! It sounds like the likely problem - now I just need to find out how to get the account reprovisioned.

I've had an AT&T tech out to replace the modem. Account was reprovisioned. Service to the house shows 100/20 to the gateway but speeds after the gateway are 100/7-8. No resolution in sight. AT&T can't figure out what's going on. I'm feeling that something is wrong in the account profile, but they can't seem to see what. Any other thoughts?

Hi @mgbhouse,
Is it correct that you are stating that at the AT&T gateway, your speed test is showing 100/20 and after, the second router it's 100/7-8? AT&T provisioned the gateway for speeds 100/20. Sometimes speeds from a second device will deviate in upload speeds. Please visit this website with information on configuring for IP Passhrough (Passthrough Mode). The AT&T provided gateway shares its Dynamic WAN IP address with a single device on the LAN. This configuration is often suitable for a customer desiring to connect third party equipment for networking, such as a router, to the AT&T provided gateway. IP Passthrough is also commonly used as an alternative to using a bridged mode. If you have any additional concerns, please feel free to reach out to us.

Hi Lafayette,
To be clear, the tech measured the speed coming into the house/gateway at 100/20. However when we plugged several computers (one at a time) into the gateway with no other devices attached to the gateway, our speed was near 100 down and 6-7 up. We had another tech out yesterday who said that he encountered another customer earlier this week with the same issue. Seems there may be a problem on AT&T's backend?
Thanks!
