Netflix performance worse on Uverse than DSL

I recently (late 12/16) got ATT Uverse. I was previously an ATT DSL customer. I find that the quality of Netflix (and Youtube) video streaming was better on DSL than it is with Uverse. How can this be? The DSL was 6 MBPS. I am supposed to now have 45 MBPS. The passwords for network access are correct. It is not a log in issue. The videos are just far more pixelated than previously and frequently stop to buffer. Can anyone suggest a fix? This is just unacceptable. Going backwards functionality wise????

  1. What type of device are you using for Netflix?
  2. Am I correct in assuming you are connected via WiFi?
  3. Please list all the other devices in your at home network and how they connect?

Out of the shrink wrap, so to speak, a U-verse install can discover some home network challenges that will slow the home network down.

 

Without the answers to my questions, the only thing I can suggest right now is to disable IPv6 on your AT&T provided router/gateway.

Thanks for your response. We have two TVs connected via wifi. I also have my "main" PC (Windows 10) connected directly to the modem by ethernet (this is the only device that get the 45 MBPS I signed up for) and two laptops (one a MacBook Pro, the other a Windows 10 laptop, both connected via wifi). There is a connection for  DirectTV via a little box to the router.  Finally we have two phones in the house that connect via wifi. The wifi "penetration" in our house is relatively poor when you get out of the room that the router is in (best we can get is usually about 12, occasionally up to 20 MBPS with Speedtest on our phones or laptops in other rooms).

 

Regarding the TV internet connections: I am using a PS3 (software is up to date) to stream to the first TV and a Roku to stream to the other. The experience seems degraded (compared to previous DSL performance nominally at 6MBPS) on both, but the TV "fed" by the PS3 is the worst. This is also the TV farthest from the router. Really a disappointment. Had I known it was going to be this bad I would have tried a different provider (Charter). I'm not talking subtle here. The videos are VERY pixelated on Youtube and perhaps slightly less so but still disappointing on Netflix.

Thank you for the great info. My remarks are going to be based on the probability that you have a 5268ac as a router/gateway provided by AT&T. 

 

It is extremely important that you disable IPv6. That can be done on the Settings/LAN/IPv6 panel of the 5268ac.

 

Next, make sure that the PS3 and the Roku are connecting to the 5G WiFi. The SSIDs configured in the 5268ac should be the same but the 5G should have the suffix of "5G" added to the SSID to differentiate. The laptops, assuming casual, not at the same time as watching TV, use can connect to 5G but in most cases not necessary.

 

Since you have a MacBook let me give you the names of a couple of apps that I use that have proven to be invaluable. "WiFi Explorer" and "NetSpot". Make sure that you haven't buried the 5268ac in a cabinet because that will degrade WiFi signal. After you survey your home with NetSpot you may consider installing a WiFi extender (choose a known brand and don't go cheap). WiFi Explorer will also tell you if there is channel overlap with your neighbors.

Can you explain why disabling IPv6 is desireable? Just so I understand....

 

I only see one SSID when I connect devices to my ATT home network....how do I tell which one is 5Ghz and which is 2.4Ghz?

 

I have the ATT 5268AC router, and it has two "broadband lights", so I think it is a dual band router.....

IPv6 is not completely implemented in the AT&T network. However, on the boundaries of the AT&T network it is enabled to a degree so if you look at your 5268ac you would information that would mislead you into believing IPv6 will work. That said, many consumer devices now support IPv6 and if those devices see IPv6 coming from the 5268ac they will attempt to connect to IPv6 resources that are unreachable and whatever reply comes from the 5268ac causes those devices to attempt again and again and again degrading the IPv4 traffic throughput.

 

SSID - You will have to go to configuration of the 5268ac (Settings/LAN/WiFi) and make sure that both 2.4 and 5 GHz bands are enabled and have different SSID, changing if necessary.

Thanks. I have done all of this (renamed the 2.4 and 5 GHz bands and disabled IpV6. I'll let you know if things improve.
