If your connection seems to slow down specifically during video streaming, throttling is worth ruling out.
Bandwidth throttling is when an internet provider deliberately slows certain types of traffic, sometimes including video streaming, usually during periods of high network demand.
If a general speed test shows a fast connection but streaming specifically still struggles, throttling targeted at video traffic is one possible explanation, though a congested home network is a more common one — rule that out first with our guide on fixing buffering while streaming.
Beyond confirming the cause, options are largely limited to your internet plan and provider — a stronger home network setup won't resolve throttling that's happening upstream.
