If OBS’s Network Dropped Frames counter is rising, the connection from your computer to the selected streaming ingest server is unstable or cannot sustain the configured bitrate. That does not, by itself, prove the encoder is at fault—or that Indian broadband as a whole is the cause. A speed test can look healthy while the upload path to a particular server has brief dips or congestion.
First, confirm which frames are dropping
Open OBS’s Stats window and check its log. Network dropped frames point to the connection to the ingest destination. Rendering lag and encoding lag are separate counters: they indicate different problems and need different troubleshooting. This guide addresses network drops.
OBS describes network drops as a sign that the connection to the remote server is unstable or cannot keep up with the configured bitrate. OBS discards frames rather than letting the stream buffer. The counter identifies a connection-capacity problem, not the specific cause: it may involve the home network, upload capacity, ISP routing, congestion, or the destination path. OBS’s connection troubleshooting guide, updated September 30, 2024, explains the distinction.
Why a good speed test may not be enough
A download result does not tell you whether your upload to the chosen ingest server will remain steady. Even a high upload result from one speed test is only a snapshot; a 24/7 stream needs the connection to carry its bitrate continuously, including during brief fluctuations and household network use.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
In a 2021 controlled study, the authors observed bursty frame drops when available bandwidth fell below the configured encoding bitrate; some bursts reached two seconds’ worth of frames. The study also reported average stall ratios of 3.5%, 1.0%, and 2.1% for the three services it tested. Those are results from the study’s test setup, not measurements of Indian broadband or predictions for your stream. They illustrate why an average or peak bandwidth figure can conceal short dips. The Livelyzer study examined this behavior.

Record the symptom in OBS
Use View → Stats in OBS and note the network-dropped-frame count or percentage, configured bitrate, and observed bitrate. Check the OBS log for the affected period. If rendering or encoding lag is increasing instead, investigate those categories separately rather than treating them as a broadband upload problem.

Compare Wi-Fi with Ethernet
If possible, connect the streaming computer directly to the router with Ethernet and compare under similar stream conditions. OBS warns that Wi-Fi can be unstable for streaming and recommends a wired connection. A Cat 6 Ethernet cable can be a reasonable way to make this comparison if you need one, but a cable cannot fix ISP congestion or a routing problem beyond your home network. OBS’s network connection guide covers connection types.
-
Lower bitrate using sustained upload as your guide
OBS says bitrate depends on stable upload capacity and platform limits. Its guide suggests 75% of total upload speed as an approximate starting point—not a guaranteed safe setting for every connection or an unattended 24/7 stream. Observe the connection over time, account for other household traffic, and leave room for normal variation. Your platform’s bitrate limits also apply. If drops continue, test a lower bitrate and monitor both stability and picture quality.

Test a different ingest server
Where the platform offers a choice, change only the ingest server and compare the drop count and bitrate stability over a similar observation period. A different result suggests the path to one destination may matter; it does not identify which network operator is responsible.
-
Check local network software and equipment
OBS lists VPNs, security software, network-priority utilities, outdated drivers, modem or router connectivity, faulty cables, network cards, switches, and extenders among possible contributors. Try reversible checks first: temporarily disconnect a VPN if appropriate, check cables and router connections, and update network drivers. Follow OBS’s guide for operating-system-specific changes. Its TCP pacing and network-optimization steps apply to Windows only; if its IPv4-only suggestion makes no difference, restore the default IPv4/IPv6 setting.

Contact your ISP if the issue persists
OBS notes that route congestion or changes on the ISP side may be outside your control. Keep the affected times, OBS logs, selected ingest server, bitrate, wired-versus-Wi-Fi results, and upload observations from the affected period. Share those details with your provider rather than relying only on a download result. OBS recommends contacting your ISP when its troubleshooting does not resolve connection issues.
What dynamic bitrate can—and cannot—do
OBS dynamic bitrate can lower the bitrate when the connection cannot keep up, which may reduce dropped frames during variable capacity. It does not repair the underlying connection and can make the picture less detailed while bitrate is reduced. For a nature stream, watch the output over time so changes in image quality are not mistaken for a stable fix. OBS describes dynamic bitrate as a fallback, not a solution to the underlying connection issue.

Separate broadcaster-side drops from viewer buffering
If OBS reports no network drops but viewers say the stream buffers, do not assume your Indian broadband upload is the cause. Viewers have their own devices, networks, and locations. Consider the stream bitrate and whether the platform provides transcoding options for different playback qualities. First establish whether OBS itself is dropping network frames; viewer complaints alone do not diagnose the sender’s connection. OBS’s troubleshooting guide discusses viewer playback considerations.
What TRAI’s broadband guidance does—and does not—tell you
TRAI says it does not prescribe a minimum broadband upload or download speed. Its broadband FAQ says providers must state typical speeds in tariff offerings and that at least 90% of measured samples during testing must meet or exceed the declared typical speed. That threshold does not guarantee a particular line will sustain a chosen livestream bitrate at every hour or reach a specific streaming server without congestion. The FAQ’s publication date is not stated on the surfaced page. TRAI’s MySpeed portal is its measurement resource, not a current ranking of providers or a diagnosis of a route to a streaming platform. Read TRAI’s broadband FAQ.
Prepare useful evidence before asking for help
- When it happens: dates and times, and whether drops persist or recur at particular periods.
- What OBS reports: the network-dropped-frame count or percentage, log, configured bitrate, and observed bitrate over time.
- Where the stream goes: platform and selected ingest server, plus whether changing the server or service changes the symptom.
- Your local setup: wired or Wi-Fi connection, router and modem details, and relevant network software.
- Upload observations: repeated checks during the affected period, not just a download test or a single peak upload result.
This information helps distinguish a local connection issue from a problem associated with a particular route or destination. It is a practical troubleshooting record, not a prescribed TRAI complaint format.
