Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →To fix dropped frames while sending a YouTube Live stream over Airtel broadband, first check the encoder’s stream-health messages, then measure upload speed on a wired connection and compare it with your total stream bitrate. Reduce the video bitrate, resolution, or frame rate if the connection cannot sustain the stream with roughly 20% upload headroom. This diagnoses outgoing stream problems; it is different from viewers’ playback buffering.
1. Find out whether the encoder or connection is responsible
Before changing settings, run a test stream with movement and audio similar to your planned broadcast. In YouTube Live Control Room, watch stream health and note when frames drop. Check the encoder’s own status for network drops, rendering or encoding lag, and high CPU use. YouTube recommends testing under representative conditions and monitoring stream health.

If the local preview or a recording already looks poor, investigate the source and encoder first. If the encoder output is healthy but YouTube reports a connection problem, continue with the network checks below. YouTube also advises considering the encoder when viewers on different networks report errors; viewer reports alone do not prove an Airtel fault.
2. Check encoder settings and load
Update your encoder software and compare its codec, bitrate, frame rate, and keyframe interval with the settings selected for the YouTube stream and any Live Control Room warnings. YouTube recommends CBR, RTMP or RTMPS, a two-second keyframe interval (no more than four seconds), and a test that resembles the real broadcast.

For H.264, YouTube’s recommended live ingest bitrates are:
| Resolution and frame rate | Recommended bitrate | Minimum bitrate |
|---|---|---|
| 720p at 30 fps | 5 Mbps | 3 Mbps |
| 720p at 60 fps | 8 Mbps | 3 Mbps |
| 1080p at 30 fps | 14 Mbps | 5 Mbps |
| 1080p at 60 fps | 17 Mbps | 6 Mbps |
These are YouTube encoder recommendations, not a measurement of your Airtel upload capacity or a guarantee of stable streaming. If your connection cannot reliably sustain the selected bitrate, test a lower resolution or frame rate. Choose based on the visual detail or motion your broadcast needs and on measured, stable upload capacity. For other resolutions, frame rates, or ingest codecs, use YouTube’s live encoder settings and bitrate table.

- DUAL-BAND WIFI 6 ROUTER: Wi-Fi 6(802.11ax) technology achieves faster speeds, greater capacity and reduced network congestion compared to the previous gen. All WiFi routers require a separate modem. Dual-Band WiFi routers do not support the 6 GHz band.
- AX1800: Enjoy smoother and more stable streaming, gaming, downloading with 1.8 Gbps total bandwidth (up to 1200 Mbps on 5 GHz and up to 574 Mbps on 2.4 GHz). Performance varies by conditions, distance to devices, and obstacles such as walls.
- CONNECT MORE DEVICES: Wi-Fi 6 technology communicates more data to more devices simultaneously using revolutionary OFDMA technology
- EXTENSIVE COVERAGE: Achieve the strong, reliable WiFi coverage with Archer AX1800 as it focuses signal strength to your devices far away using Beamforming technology, 4 high-gain antennas and an advanced front-end module (FEM) chipset
- OUR CYBERSECURITY COMMITMENT: TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Secure-by-Design pledge. This device is designed, built, and maintained, with advanced security as a core requirement.
3. Measure upload speed and leave headroom
Run a speed test that reports upload speed and ping. Download speed alone does not tell you how much capacity is available for sending a live stream. YouTube recommends keeping about 20% headroom above the total live bitrate. Count both primary and backup streams if you use one, and allow for other people or devices using the connection.
Recommended Free Tools
For example, a single H.264 stream at 720p30 uses YouTube’s recommended 5 Mbps video bitrate. Planning for approximately 20% room above that means the available upload should be around 6 Mbps or more, before accounting for other traffic. This is a planning guideline, not a guarantee; actual stability depends on the connection and route to YouTube.
Rank #3
- Next-Gen Gigabit Wi-Fi 6 Speeds: 2402 Mbps on 5 GHz and 574 Mbps on 2.4 GHz bands ensure smoother streaming and faster downloads; support VPN server and VPN client¹
- A More Responsive Experience: Enjoy smooth gaming, video streaming, and live feeds simultaneously. OFDMA makes your Wi-Fi stronger by allowing multiple clients to share one band at the same time, cutting latency and jitter.²
- Expanded Wi-Fi Coverage: 4 high-gain external antennas and Beamforming technology combine to extend strong, reliable, Wi-Fi throughout your home.
- Improved Battery Life: Target Wake Time helps your devices to communicate efficiently while consuming less power.
- Improved Cooling Design: No heat ups, no throttles. A larger heat sink and redefined case design cools the WiFi 6 system and enables your network to stay at top speeds in more versatile environments.
Repeat the test at the times when dropped frames usually occur. Airtel recommends pausing background downloads and reducing connected devices during testing. A strong result at a quiet time does not establish that upload performance will remain stable during a busy stream.
4. Compare wired broadband with Wi-Fi
Connect the streaming computer directly to the Airtel router or ONT with an RJ45 Cat5 or Cat6 Ethernet cable. Repeat the upload test and, if possible, a test stream with other conditions unchanged. Airtel recommends a wired test because Wi-Fi can reduce measured speed and is susceptible to interference.

- COVERAGE IN EVERY ROOM: Covers up to 1,500 sq. ft. for up to 20 connected devices. Walls, floors, and interference can reduce range. Larger or multi-story homes may benefit from a NETGEAR Orbi mesh WiFi system.
- Wired is stable, Wi-Fi is not: focus on wireless signal and interference. Move the router to an open, central location, reduce obstructions, and test again near the streaming computer.
- Both wired and Wi-Fi struggle: check encoder load and background traffic, then gather evidence for Airtel support if the wired connection remains poor.
Airtel describes 2.4 GHz Wi-Fi as longer-range but slower, and 5 GHz as faster but shorter-range. Choose based on signal quality at the streaming device and retest; switching bands or channels is not a guaranteed fix for packet loss. For Airtel Xstream Fiber, the Airtel Thanks app also offers Wi-Fi diagnosis or optimization. App labels can change.
