Quick answer
IPTV needs a steady connection more than a fast one. Ethernet, a 5 GHz Wi-Fi band and a router placed close to the TV fix most network-related playback problems.
What you might see
- Buffering on Wi-Fi but not on Ethernet
- Playback worse in some rooms
- Drops when others use the internet
Likely causes
- Weak Wi-Fi signal
- 2.4 GHz band congestion
- Outdated router firmware
- DNS resolution problems
Step-by-step fixes
- Use Ethernet. Wired is always more stable. Powerline adapters or mesh Wi-Fi are good alternatives.
- Switch to 5 GHz. 5 GHz Wi-Fi is faster and less congested over short distances.
- Update router firmware. Check your router's admin page or app for updates.
- Try a different DNS. Setting a reputable public DNS on the router or device can help if channels fail to resolve.
Check it worked
Run a speed test on the viewing device and play a channel for 10 minutes.
