Quick answer
If streams work in the morning but buffer every evening, or fail on one internet connection but work on another (for example, mobile data), your internet provider's network may be the cause.
What you might see
- Buffering only at peak times
- Works on mobile hotspot but not home broadband
- Sudden drop after an ISP router change
Likely causes
- Network congestion at peak hours
- Traffic management by the ISP
- DNS or routing problems
Step-by-step fixes
- Compare connections. Test the same channel on your phone's hotspot. If it works there, the home connection is the variable.
- Restart and update the router. Restart the ISP router and check for firmware updates.
- Contact your provider. Report speed and stability issues at peak hours to your ISP.
Check it worked
Repeat tests at the same time of day after each change.
