Broadband Test Tools UK

Broadband test tools help you measure the symptom instead of guessing. Choose the right test for speed, high ping, lag under load, packet loss, slow downloads, IP details or fibre availability.

Choose the right diagnostic

Start with the symptom, not the biggest speed number

A speed test checks capacity. Ping, packet loss, loaded latency and bufferbloat explain why gaming, video calls or browsing can still feel poor. Use the matching tool below, then follow the linked diagnosis.

Core tests

Internet performance and stability tools

Ping Test

Measure latency, jitter and failed browser requests across 32 samples.

Run the Ping Test

Packet Loss Test

Check for failed or late requests that can cause rubber-banding and call glitches.

Run the Packet Loss Test

Bufferbloat Test

See whether downloads or uploads cause latency to rise while the line is busy.

Run the Bufferbloat Test

Internet Speed Calculator

Estimate download times and the speed needed for files, games and updates.

Open the Speed Calculator

Connection identity

Check your public IP, ISP and NAT boundary

What Is My IP & CGNAT Checker

See your public IPv4/IPv6, ISP and ASN, then compare the router WAN address for CGNAT or double NAT.

Check My IP Address

Coverage and upgrades

Check whether a faster connection is available

Broadband Availability Checker

Use a postcode to review local Ofcom coverage context and likely network routes.
