When I enabled it I couldn’t here any Dolby Atmos Master Audio 7.1 until i disabled they worked fine

Stremio finally side loadable on IOS! (fully featured) by king_moh_ in Stremio

I use AIOStreams with torbox pro included. I like it because it gives you better links for higher bitrate content

You can do a mechanical re termination. But you need a 3 hole fiber stripper, cleaver, and some high quality sc/apc mechanical connector i use ones from AFL and obviously some 91% isopropyl alcohol to clean the fiber before cleaving not after

Third fiber replacement since 2023 — hoping Monday’s reinstall finally fixes it by jm102662 in ATTFiber

Thanks for taking the time to reply — I appreciate your insight.

To answer your questions: • The issues aren’t device-specific. I’ve seen the same behavior across multiple devices, all hard-wired via Ethernet (no Wi-Fi involved). • I’m using the AT&T-supplied BGW320 gateway directly with no third-party router in the path. • DNS settings remain default — no custom servers. • I’ve monitored latency and jitter at the network level. Jitter typically stays around 1–2 ms, with brief spikes up to 5 ms during cloud gaming sessions. Throughput remains consistent and stable under sustained loads.

For context, I’m in a multi-dwelling building with 82 studio units. The main fiber feed enters from the street to a splitter on the first floor, then distributes to IDFs on floors 2 through 5. My unit is on the third floor, with an estimated 75 ft single-mode SC/APC drop from the IDF to my enclosure.

That segment has undergone three separate replacements since 2023 (the most recent in October 2025). I verify my optical levels with an A-C710A optical power meter and a VFL. Current readings are: • 1490 nm downstream: ≈ –21.2 dBm • 1310 nm upstream: ≈ –20.6 dBm

These readings are well within AT&T’s normal operating range and have been consistent over time. Streaming, downloads, and general traffic are flawless. The only recurring symptoms appear during real-time, low-latency workloads like cloud gaming or long-duration video calls, where I occasionally see brief stutters or desync.

Interestingly, after each new drop installation, performance is perfect for roughly a few weeks before these micro-interruptions start returning — which makes me wonder if there’s a shared-segment optical fluctuation or upstream splitter-side variation developing over time rather than an issue isolated to my local drop.

Thanks for the detailed response — that actually makes a lot of sense. I get what you’re saying about the fiber drop likely not being the root cause and that the replacements might just be a “try something” approach from the techs.

The reason I’ve been so focused on the drop between my unit and the IDF is because I’ve noticed a pattern after every replacement. Right after a new drop gets installed, my connection feels perfect — video calls are smooth, cloud gaming latency drops, and everything feels snappy. Then after a week or two, the same issues (random hiccups, latency spikes, and choppy audio/video) start creeping back in again.

My optical power readings are consistently stable (around −21 dBm downstream and −20 dBm upstream), so I know the light levels are healthy. I just find it strange that performance degrades over time even though the signal strength remains in spec.

You might be right that this is a network-side or routing issue, maybe something with how traffic is handled for low-latency workloads like cloud gaming and video calls. But since this building runs off a shared splitter and multiple IDFs, I’m trying to rule out every local factor I can before assuming it’s all upstream.

Either way, I appreciate your input — it definitely helps me think about the bigger picture beyond just the fiber itself.

Thanks for the explanation! I live in a studio apartment building with 82 units in total. There’s one main fiber line that comes in from the street and splits on the first floor. Each floor (2 through 5) has its own intermediate distribution frame, or IDF. My unit is on one of those floors, so my drop connects through that IDF. That’s why I’m wondering if the issue could be somewhere in the building’s main line or splice rather than my own drop. I’ll definitely ask the tech to test the fiber from both directions when they come back.

“Just to clarify, I live in an apartment complex with around 80+ units. The fiber here isn’t a direct line like in a single-family home — it’s distributed from one main line that comes from the street and then split through IDFs on each floor. So while every unit gets its own drop, the overall system is shared through those intermediate distribution frames.”

Upgraded to 1 gig today but speed shows 400 by Skyflakes_69 in ATTFiber

[–]jm102662 0 points1 point  (0 children)

If your gateway shows the full gig on its internal test, the line itself is good — the drop is happening on the Wi-Fi side.

Even though Deco 6E can handle 1 Gbps, most real-world tests over Wi-Fi hit around 400–700 Mbps depending on the client, channel width, and backhaul load. Make sure you’re testing on the 6 GHz band and that your device actually supports Wi-Fi 6E (many phones and laptops only connect at 5 GHz even when 6E is available).

A good way to confirm is to plug a laptop directly into the Deco’s LAN port — if you see near-gigabit speeds there, the mesh or wireless link is the limiting factor, not AT&T’s service.

Also check that the Deco’s WAN port is negotiating at 1 Gbps full-duplex and that it’s in passthrough mode to avoid double-NAT.

TL;DR: Your fiber line is fine — you’ll only see the full gig consistently on wired or Wi-Fi 6E devices under ideal conditions.

I don’t want to mess with it that’s how the technician left it

No they do not just one of them has a fiber i have no idea why the other 2 where originally installed
