Recently the gateway was replaced to new 5268AC gateway because of my frequent complaints of u-verse service dropouts and slow internet, after several weeks of service and a couple of tech visits of line, home wiring, signal testing, etc it has not improved. I was sold an upgrade to 24 Mbps to resolve my slow internet browsing but no significante improvement, the internet speedtest is really meaningless as most of the time it does clock at 24 -30Mbps but the LATENCY varies significantly as much as 22 - 380 Ms which obviously the speed test is good with 22Ms but when surfing its slow as its not a single burst/stream access. I tend to believe that its due to saturation or limited bandwidth at my point of service, obviously ATT does not accept it.
Anyone having similar issues or suggestions ?

Devices connected to a local ATT server (speed test.net) does not have problems....
Only when you go off network is issue seen?
Routing, congestion, etc.
Could try changing the devices DNS setting.... 220.127.116.11 or 18.104.22.168 are two possible to see if can acquire a different routing path.
Or consider the Uverse internet Terms Of Service (TOS) agreement
2. AT&T High Speed Internet Service
AT&T High Speed Internet Service (referred to as "the Service") is composed of narrowband or broadband access to Internet, and offers you a capability for acquiring or retrieving information from; generating, storing, transforming, processing, or utilizing information on; or making available information to other Internet end points connected directly or indirectly to AT&T's network. Because the Internet consists of multiple interconnected networks and most Internet end points (e.g., websites and other content providers) are not directly connected to AT&T's network, AT&T must connect to and exchange traffic with other networks to provide its subscribers the capability of uploading data to or downloading data from Internet end points that are connected to those networks. To that end, AT&T has entered into commercially negotiated agreements to exchange traffic with such networks on mutually agreeable terms. Consistent with its longstanding practice, AT&T does not warrant that it will establish or expand the connections between its network and other networks except on such mutually agreeable terms. To the extent AT&T is unable to reach agreement on terms of interconnection or network expansion with these other networks it could affect your service These impacts on your service performance are described in more detail in AT&T's Open Internet notice. AT&T therefore makes no promise express or implied that you will be able to upload data to or download data from Internet end points connected to other networks at any particular speed.
Like the other networks that make up the Internet, AT&T's is a shared network, which means that the transmission links and other network resources used to provide the Service are shared among AT&T's subscribers. AT&T manages this network for the benefit of all users based on a variety of factors, and our technical expertise.
AT&T offers many broadband service options, each of which has a different service capability speed range. The term speed is commonly used as a shorthand way to describe the capacity at which a particular broadband internet access service can transmit data. This capacity is typically measured in the number of kilobits, megabits or gigabits that can be transmitted in one second (Kbps, Mbps or Gbps). Some applications like a short email without attachments or basic web browsing do not require high service capability speeds to function optimally, while other activities like transferring large data files can be performed faster with higher-speed services. Your service capability speed may not be suitable for some applications, particularly those involving real-time or near real-time, high-bandwidth uses such as streaming video or video conferencing.
The current speed ranges AT&T offers may be found at http://att.com/speedtiers, which identifies the downstream and upstream rates at which your line transfers internet access data between the network interface device at your home, office or apartment building to the point you connect to AT&T's network. Our wired broadband Internet access customers should expect to see service capability speeds within the speed tier of their service plan. For example, a customer with AT&T's High Speed Internet Elite Service should expect service capability download speeds between 3.1Mbps and 6.0 Mbps between the network interface device at your premises and the point you connect to AT&T's network. The high-end of this range represents expected maximum speed capabilities. For more information about how AT&T helps transmit your information to points on the Internet, how AT&T manages the network, broadband options, including different service capability and expected and actual speed ranges, device attachment rules, activities which may impair or degrade your internet experience and for additional information regarding network practices with respect to data usage caps related to AT&T Broadband Internet access services, please visitatt.com/broadbandinfo.
Because service performance varies on an end-to-end basis, AT&T's service capability speeds are limited to, and measured between, your location and a point on AT&T's network, which constitutes only one segment of the end to end transmission path connecting the end user to Internet websites or content providers. End-to-end performance of your Service depends on a variety of factors, including (but not limited to): the number of subscribers simultaneously using the network; customer location; destination and traffic on the Internet; Wi-Fi connectivity; interference with high frequency spectrum on your telephone line; wiring inside your premises, office or apartment; the capacity or performance of your devices or modem; the server with which you are communicating; internal network management factors (including Overhead, which refers to the various control and signaling data required to achieve the reliable transmission of Internet access data); and the networks you and others are using when communicating. In addition, your use of other AT&T services (such as U-verse video, voice, Unified Messaging and other services) that share the capacity of your broadband connection with the Service may impact the amount of capacity available for your use of the Service at that particular time and thus affect the performance of the Service. Consequently, AT&T does not guarantee the performance of your service on an end-to-end basis.

thanks, I have read the ATT TOS which is fine and not much different than other service provider, you are the first from ATT to bring it up but anyway you suggested an ip change to make the network re-route the path. Am i correct to assume the ip address you gave is just a base address which the network server will then assign the unique ip to my gateway. I know what my current dynamic ip address is, do i need for ATT to re-route ?

He's telling you to use Google DNS server instead of the AT&T DNS (Domain Name System) server. You would set that up in your computer's Network Interface Card settings.

Thanks for the clarification, as I was a little confused as I took it to changing the gateway ip address which concerned me as to ip conflict in a huge node network. I am looking to resolve / improve the gateway access, rather than configuring all my NIC which I do have several.
08-30-2016 2:38 PM
Try just changing one of the NIC's to the Google DNS and see if the behavior your seeing changes. If it does, it's nothing on your internal network causing the latency. It's outside of your home, then trying to get AT&T to correct it is going to be almost impossible.
Most speed tests I run the latency is anywhere between 15 and 25.

Thanks, I did notice some improvement after making the DNS change, although not consistant and slow. It seems that where in the que my request falls determines the speed of the responses , bottleneck.
Once again thanks for the input.

Re: 5268AC gateway
"Devices connected to a local ATT server (speed test.net) does not have problems....
Only when you go through vpn is issue seen (Internet speed slows way down)? Routing, congestion, etc. Could try changing the devices DNS setting.... 22.214.171.124 or 126.96.36.199 are two possible to see if can acquire a different routing path."
Please clarify more. Are the DNS settings to be changed in the [device's] OS (ex: desktop computer with ethernet/dsl) via Control Panel [Network and Internet, Adapter Settings, Properties, TCP/IPv4, TCP/IPv6, Preferred/Primary DNS server, Alternate/Secondary DNS server], or are the DNS settings to be changed in the "router" via gateway user interface (Settings, LAN, DHCP, First DHCP, Last DHCP)?
Seriously, in the gateway user interface, the "Broadband," tab does not allow changes to Current Internet Type or Connection, but the "LAN, DHCP" tab does allow changes to DHCP configuration. If you have accessed "Broadband, Link Configuration", there is a section (Supplementary Network) in which router address and subnet mask can be changed but, not certain if that section is the pertinent one to change network settings to use the google public dns to help with "my Internet speed has dropped off face of the earth due to the vpn and I really want to use my vpn and browse the internet using speeds faster than geologic ages" problem.
