Fix a slow connection

Find where slow Internet use begins with controlled device, Wi-Fi, Ethernet and service comparisons, then choose a suitable next step.

Investigate slow Wi-Fi with controlled location, device and Ethernet comparisons, accounting for the band, load and path to the Internet.

High ping: compare the destination, method and load, separate brief spikes from sustained delay, and investigate Wi-Fi, your traffic and service data.

Find why video playback keeps buffering: compare the app, device, Wi-Fi and Ethernet, check actual playback conditions and avoid blaming a fast or slow speed test alone.

Diagnose slow uploads with a controlled test, a realistic file-transfer calculation and comparisons between devices and services.

Slow downloads can involve units, Wi-Fi, competing traffic, a device or a remote service. Use a controlled comparison before changing your router or plan.

Separate network delay, low FPS and cloud-streaming problems. Compare game statistics, Ethernet, your own traffic and region before changing a plan or device.

Packet loss means sent packets do not reach their destination. Compare devices, connections and repeatable tests; missing ping replies alone do not identify the fault.

Find where repeated internet disconnections begin: compare devices and Wi-Fi with Ethernet, save router logs, and give your provider useful evidence.

Freezing video calls can involve the network, devices or individual participants. Compare evidence to narrow down the cause.

Compare transfer units, request timing, app limits and controlled downloads to investigate a fast speed test alongside slow file transfers.

Distinguish a lost Wi-Fi connection from missing internet or one failing app. Compare devices, Ethernet and event records before changing settings.
