Identify buffering symptoms

Buffering presents as video pauses, pixelation, or audio dropping out. Note when it happens: peak evening hours, specific channels, or during high-speed sports. This pattern helps narrow down the cause.

Common NBN causes

  • Congested CVC capacity: Your ISP may oversubscribe your local NBN point.
  • Wi-Fi interference: Thick walls, microwaves, or neighbours on the same channel degrade signal strength.
  • Underpowered routers: Standard ISP routers often lack the processing power for multiple HD streams.
  • Outdated firmware: Old router firmware can mishandle multicast/unicast traffic.

Quick fixes that work instantly

  • Restart modem and router to clear memory leaks.
  • Connect your streaming device via Ethernet or use a powerline adaptor.
  • Switch to Luna Streams’ backup Oceania server in the player settings.
  • Reduce resolution to 720p temporarily during peak congestion.

Advanced router optimisation

  1. Update router firmware to the latest release.
  2. Enable Quality of Service (QoS) and prioritise your IPTV device’s MAC address.
  3. Switch Wi-Fi channels using apps like WiFi Analyzer to avoid crowded frequencies.
  4. Disable IPv6 temporarily if your ISP implementation is unstable.
  5. Install a third-party router rated for high throughput (e.g., ASUS, TP-Link Archer, Ubiquiti).

Luna Streams tools & settings

Luna Streams includes built-in options to mitigate buffering:

  • Server selector: Switch between Primary AU, Backup NZ, and Global nodes.
  • Stream format toggle: Choose between H.264 and H.265 streams based on device capability.
  • Catch-up buffer: Enable 30-second delayed playback for ultra-stable sports streaming.

When to call your ISP

If buffering persists after the steps above, call your ISP with speed test data from peak and off-peak hours. Ask about:

  • Upgrading your NBN plan or moving to a higher CVC ISP.
  • Replacing ageing modems with Wi-Fi 6 hardware.
  • Checking for line faults or noise on copper segments.

Document your findings and escalate if your service falls below the minimum speed guarantee.
