When OBS drops frames during a YouTube stream, first check which counter is increasing: network dropped frames, rendering lag or encoding lag point to different problems. Network drops mean the connection to YouTube’s ingest server is unstable or cannot keep up with the configured bitrate; they do not, by themselves, prove ACT Fibernet is at fault.
To test whether shared upload use is contributing, compare similar streams with other uploads paused and active, then lower the bitrate and repeat over Ethernet. Keep timestamps and OBS logs for each test. A speed test or one good night is not enough to establish a pattern.
Check which kind of frames OBS reports dropping
Open OBS’s Statistics window while streaming and note which figure changes. The key distinction is whether OBS is dropping frames because it cannot send them over the network, or whether it cannot render or encode frames quickly enough on the computer. “Dropped frames” in ordinary conversation can refer to all three, but the remedies are different.
Network dropped frames concern the connection between OBS and the remote ingest server. OBS explains that this can happen when the connection is unstable or cannot keep up with the bitrate you set. Rendering lag means OBS is not rendering scenes fast enough, often because of graphics processing load; encoding lag means the encoder cannot process frames quickly enough. A busy scene, demanding output settings or an overloaded computer are plausible causes of the latter two, not evidence of a shared ACT upload problem.
Record the exact counter name and whether it rises during the same moments that viewers report stuttering. If only rendering or encoding lag climbs while network drops remain flat, focus first on OBS workload and output settings. If network drops climb while the other counters remain steady, the sending path becomes a more relevant suspect, though that still does not identify the ISP or a particular link as the cause.
Do not assume that a momentary change in the preview means the broadcast is dropping frames. The preview can behave differently from the outgoing stream. Use Statistics, and later compare its timing with YouTube’s stream-health messages, rather than relying on what the local preview looks like.
Read OBS statistics and logs
Establish a baseline before changing anything. Write down the date and time, whether the computer is on Wi-Fi or Ethernet, the output resolution and frame rate, the video bitrate, and whether anyone else is uploading files, backing up photos or sending large attachments. Note the start and end times of a test and the network-drop counter at both points. Keep a copy of the OBS log for that session.
The log provides context that a single screenshot may not: it can show the stream settings and events around a disconnect or reconnect. In OBS, use the log for the completed session that corresponds to your test, rather than combining details from several runs. If you are contacting ACT, a log and timestamps are more useful than saying only that the stream was bad last night. Avoid posting a stream key or other private account information when sharing logs.
Keep other conditions as consistent as practical. Use the same scene, video, resolution, frame rate and test duration when comparing Wi-Fi with Ethernet or household upload activity on and off. If a live public stream is not appropriate, run a private or otherwise limited test using YouTube’s available controls, and verify the current setup in YouTube Studio. YouTube recommends testing before broadcasting and using representative audio and motion; a static scene may not expose the same workload as a moving one.
A general upload test can give you a reference, but it measures a brief test under its own conditions. It does not show that upload capacity stays steady for a full stream, nor that the route to YouTube’s ingest server behaves the same way. Treat the result as one item in your notes. OBS’s stream connection troubleshooting guide also explains why network drops concern the connection to the remote server rather than automatically identifying a software fault.
If you are setting up a recurring channel, the OBS and cloud-server setup guide covers a different operating arrangement; it does not replace checking what the counters say on the computer you are testing now. For a playlist-based channel, also keep media preparation separate from the connection diagnosis. An upload workflow over JioFiber may help with preparing files, but file uploads and a live stream are different uses of the connection.
Test at a lower bitrate
A stream sends data continuously. If the available upstream capacity varies or is shared with other activity, a bitrate that seemed possible in a short test may not leave enough headroom during the broadcast. Lowering the video bitrate asks the connection to carry less data, but it can reduce picture detail. It is a test, not a guaranteed fix, and a result at one setting does not establish why the earlier setting failed.
OBS gives about 75% of total upload speed as a troubleshooting starting point for bitrate selection. Treat that as a rule of thumb rather than a promise: a short upload test can capture a peak, not the sustained capacity available during a long stream, and other devices may use the connection. If your measured result varies, leave more room rather than trying to use all of it. Do not interpret this percentage as a recommended ACT plan speed.
YouTube publishes recommended encoder bitrates by codec, resolution and frame rate. For H.264, its recommendations include 14 Mbps for 1080p30, 17 Mbps for 1080p60, 8 Mbps for 720p30 or 720p60, and 4 Mbps for 480p30. For AV1 or H.265, the corresponding published values are 10 Mbps for 1080p30, 12 Mbps for 1080p60, 6 Mbps for 720p30 or 720p60, and 3 Mbps for 480p30. These are encoder recommendations from YouTube, not minimum connection speeds or guarantees that a stream will be stable. Check YouTube’s current live encoder settings before choosing settings, as recommendations can change.
For a useful comparison, change one relevant setting at a time and write it down. You might test a lower bitrate while keeping the resolution and frame rate the same; if the symptom remains, a separate test at a lower resolution or frame rate can show whether reducing output demand changes the result. Keep the test conditions and representative motion consistent. A picture that is less detailed but stable may be preferable for a channel that must remain watchable, but the choice depends on the content and audience.
YouTube’s settings page also specifies CBR and a recommended two-second keyframe interval for RTMP/RTMPS, with a maximum of four seconds. These are configuration details to verify, not a remedy for every dropped-frame problem. If your setup already matches the platform’s current guidance and only network drops rise, continue with connection comparisons rather than repeatedly changing unrelated encoder options.
Pause other uploads and compare results
On a shared connection, an upload from another device can use upstream capacity that OBS would otherwise have available. Examples include a large cloud backup, sending a video file or another household member uploading media. This makes shared use a reasonable hypothesis to test. It does not show that ACT has a general capacity problem, and you cannot infer congestion from the presence of another device alone.
Run comparable tests with other upload-heavy activity paused and then, if practical, with normal household activity allowed. Keep the stream settings, duration, computer, router position and connection type unchanged. Note the time, activity state, OBS counters and YouTube messages in both runs. Do not start a backup halfway through one run and compare it with a different evening’s test unless you label the difference; time of day and changing conditions can confound the comparison.
If network drops occur during the active-upload test but not the paused test, repeat the comparison before drawing a conclusion. A repeatable change is evidence that shared upload use correlates with the symptom under those conditions. It still cannot tell you whether the cause is limited available capacity, router behaviour or something else along the connection. If both tests show similar network drops, other household uploads are less likely to explain that particular pattern, though the tests are not proof of the alternative cause.
If the issue is a file being uploaded to YouTube rather than live output from OBS, diagnose that separately. For channels built around recorded material, creating a seamless loop video addresses the content side; it does not establish that a live stream’s upstream path is stable. Keeping the two tasks distinct makes your connection notes easier to interpret.
Retest over Ethernet
Wi-Fi can add instability between the computer and router, which is separate from the connection from the router onward. OBS recommends a wired connection for streaming because Wi-Fi may be unstable. If you are currently on Wi-Fi, test with the computer connected to the router by Ethernet, keeping stream settings and other activity as similar as possible. A Cat 6 cable is relevant only if you need a cable suitable for the run between your equipment; buying a cable cannot fix an upstream fault.
If network drops improve over Ethernet, that points towards a difference in the local wireless segment, such as signal quality or interference, but does not prove the exact cause. Try to keep the computer in the same place and avoid changing bitrate at the same time, otherwise you will not know which change mattered. If Ethernet does not improve the result, Wi-Fi is a less persuasive explanation for that test, and it is worth looking further along the path or at the stream settings.
A wired test is also useful when other household devices remain on Wi-Fi. It does not make OBS immune to shared upload use: devices using the same connection can still consume upstream capacity. Compare wired tests with upload activity paused and active if the first comparison suggests a correlation. Record whether the problem is isolated to a particular time or appears under several conditions.
Compare findings with YouTube stream health
OBS shows what is happening at the sending end; YouTube Studio can show whether YouTube is receiving a stream and report stream-health messages. Check both during the same time window. Note when YouTube reports a problem, whether OBS network drops rise at that time, and whether the message clears or persists. A mismatch between the two views is useful context, not a verdict about which party is responsible.
Before a test, use YouTube’s current guidance for checking a live stream and choose representative audio and motion. During the test, avoid treating a single warning as definitive if OBS counters remain steady; preserve its wording and timestamp, then see whether it recurs. Conversely, an OBS network-drop counter that rises while YouTube reports an unstable incoming stream is a more coherent set of observations than either signal alone, but it still does not prove the source is ACT, YouTube or the local network.
Where practical, OBS suggests comparing with another streaming destination to see whether the symptom is specific to one service. This can help narrow the question, but a different destination uses a different ingest path and may have different settings. If one destination works and YouTube does not, that is evidence of a service-specific difference in the test, not proof that YouTube or ACT is at fault. Keep the comparison safe and appropriate for your channel, and do not expose private broadcasts unintentionally.
Decide what evidence supports an ACT connection issue
A useful case for asking ACT to investigate is built from repeatable observations, not from the title of this article or a single speed-test result. If network drops persist at a reduced bitrate over Ethernet, record the relevant settings, time-stamped OBS logs, YouTube stream-health messages, and upload-test results. Include whether other upload activity was paused and whether the same behaviour occurred with another destination, if you tested one.
A pattern that changes when household uploads are paused supports the idea that shared upstream use contributes. A pattern that improves on Ethernet supports investigating Wi-Fi separately. If drops persist across wired tests, lower bitrate and paused household uploads, the remaining evidence points beyond those two factors, but it still does not identify a fault or route by itself. ACT can use your service location and timestamps to check current local status or investigate the line; no city, plan, router or observed logs have been supplied here, so there is no basis to claim a current ACT outage or congestion.
Ask a focused question when you contact support: whether they can see a local fault or investigate instability at the recorded times. Share the counter type and the tests you repeated, rather than saying only that YouTube is buffering. Keep your notes and logs in case the issue recurs. If the problem clears, retaining the baseline still helps you distinguish a later change from ordinary variation.
For a channel that depends on a pre-recorded loop running while your computer is unavailable, the operational problem may be different from diagnosing an OBS session on a shared home connection. StreamNeo can remove the need to keep your own computer on for that kind of YouTube broadcast, but it does not diagnose or repair an ACT connection used by your OBS setup. Check that a file-based, YouTube-only workflow suits your channel before choosing it.

FAQ
Why is OBS dropping frames when I stream to YouTube?
First check whether OBS reports network dropped frames, rendering lag or encoding lag. Network drops concern the connection to YouTube’s ingest server; rendering and encoding lag concern the computer’s work. The counter helps identify which kind of problem to investigate, but does not name its cause.
Does someone else using the internet cause OBS network drops?
An upload on another device can consume shared upstream capacity, so pausing uploads is a useful controlled test. Compare otherwise similar runs and repeat the result before treating it as a pattern. A correlation with household activity is not proof of an ACT fault.
Is ACT Fibernet upload speed stable enough for YouTube live streaming?
That cannot be answered from the provider name or a generic speed test. Stability depends on your settings, sustained available upload, local connection and the route to the ingest server. Record OBS counters and YouTube messages over representative tests, including a wired test, then ask ACT to investigate with timestamps if the issue persists.
Will lowering bitrate or switching to Ethernet fix dropped frames?
Either change may improve a particular test, but neither is guaranteed to fix the cause. Lower bitrate trades picture detail for lower data demand; Ethernet removes Wi-Fi from the local connection path. Change one condition at a time and compare the same OBS counters and YouTube health messages.
