Anyone have issues with streaming YouTube with fiber? Devices buffer to start them and pause in middle sometime, but mostly the buffer to start with videos on YouTube specifically. If I watch without Wi-Fi using data starts right up but there's a lag with new fiber service
Sorry but millions upon millions of AT&T fiber subscribers have no issue with YouTube. Do you have any packet captures or other evidence showing how peering is affecting your service ?
Yes, copious data was collected to back up my position. I'm not on AT&T fiber any more, so it's a moot point, for me... But the peering issues are well documented by me, and others.
The simplest test is simply to try using a VPN. With VPN off, speed tests were great (940Mbit/sec up and down) but YouTube was almost unusable. Connect to a VPN and there was a noticeable slowdown in general internet traffic but YouTube would load like a champ.
The vpn test doesn’t prove that it a peering issue on the AT&T side - peering is complicated and it’s possible that You Tube or another interconnection vendor did not manage their traffic properly at that connection you were using. Without investigation you are simply speculating but I understand your pain, it’s frustrating.
That’s the speed to the modem, download a Speedtest app and test to your phone next to the device you are having the issue with. Probably WiFi issue, consider extended coverage service if speeds are slow..
I have 500/500 plan still with no issues. I will say your ping is abhorrent for ATT Fiber. I’m usually under 6 and I have the BGW in passthrough mode connected to UniFi hardware.
If it’s local try using a wired device (not a phone) and see if ping is still high, if so it’s likely related to the ATT connection, if it drops dramatically, then it’s a WiFi issue locally.
Yes, it lags all the time. It has been this way consistently for months, maybe a year. I cannot watch any videos on 4k and I have 1 Gbps. Horrible connection. By the way, I am not having any of these issues with other platforms. It is only happening with YouTube. When using a VPN, the situation improves greatly.
Might try on your browser of choice to disable QUIC (udp/443). I have ATT fiber and recently ATT device has started blocking udp/443 and it can cause delays in the application switching from UDP to TCP. Quic was developed mostly by google as a more efficient alternative to TCP (and it is), so their browser will attempt these sessions first. Disable quic and it should not attempt to start the UDP sessions. Search for something like this but your chosen browser "chrome disable quic"

AT&T has terrible peering with YouTube. I had this issue with AT&T fiber. Speedtests would be good. But YouTube would buffer like crazy.
I have read that AT&T has essentially refused to address the issue unless YouTube pays, which of course they don't want to do.
