> Signs your internet provider throttles or blocks IPTV, a simple test to prove it, and the fixes: VPN, DNS, and talking to your ISP.

Some internet providers manage traffic at busy times, and video streams are a common target. Others block certain servers outright.

## Signs

- [Buffering](https://blog.vikingiptvofficial.com/iptv-buffering-fixes/) mostly between 7 pm and 11 pm, fine during the day.
- Speed tests look fine, but streams stutter.
- Everything works on mobile data or a friend's connection.
- Big live events are much worse than ordinary evenings.

## Test it

- In the evening, play a busy channel and note buffering.
- Switch to mobile hotspot: better? Your home connection is the problem.
- Back on home internet, connect a [VPN](https://blog.vikingiptvofficial.com/iptv-vpn-guide/) in your country: better? Your ISP is likely throttling.
