'Slow internet' is rarely one problem — it's usually bandwidth, latency, packet loss, DNS, or Wi-Fi pretending to be each other. Work through this workflow to isolate which one is hurting you.
Download and upload Mbps tell you bandwidth. Ping and jitter tell you whether real-time applications (calls, gaming) will feel smooth. Compare against your plan, not against someone else's connection — a 100 Mbps plan can't deliver 500 Mbps no matter what.
Run through these steps in order. Each step links to the right diagnostic tool.
No. Bandwidth (Mbps) and latency (ms) are independent. You can have a 1 Gbps line with 200 ms ping and feel slow on video calls but fast on downloads.
Wi-Fi adds airtime contention, interference, and signal loss. If ethernet is fine, the bottleneck is your radio environment, not the ISP.
Yes — encryption overhead and extra hops add latency and reduce throughput. Test with the VPN off to measure the cost.
Under 1% is fine for browsing. Above 2% causes noticeable video, call, and gaming issues. Anything sustained is a red flag.
