Start with a wired connection
If your device supports Ethernet, use it as a baseline before comparing Wi-Fi.
Internet Speed Test
Test your connection — download, upload and latency
Local development test only
This server is on your own computer. Its results do not measure your ISP or internet speed, BDIX connectivity, or OTT cache performance.

Frequently Asked Questions
How does this speed test work?
Your browser exchanges test data with the selected server and times HTTP requests. Nothing runs before you choose a server, press Start Test.
How do I get the most useful result?
Connect with Ethernet, pause other transfers and repeat the test at different times. If you test over Wi-Fi, record where you are and which device you used.
Why do download and upload speeds differ?
A package may advertise different speeds in each direction. Server capacity, Wi-Fi, traffic and the single-connection test method also influence results.
Does a BDIX result measure all internet traffic?
No. A local-network or cache test applies only to that configured endpoint. It does not prove access to every peer or streaming cache.
Are my results saved?
ISP Guide BD keeps the result in this page only. You can share a result link, save an image or download the data. The selected measurement service receives your network address.
A useful result starts with a fair test
Get a clearer picture of your connection.
Pause competing transfers
Choose a moment without large downloads, cloud backups or streaming on the connection.
Repeat under the same conditions
Keep the device and endpoint the same. Note the time and save a result when it helps.
Read all four measurements
There is more to your connection than download speed.
This test reports a transfer between your browser and the selected endpoint. Read the values together, then compare several results from the same setup.
Mbps
Download
How quickly this test receives data from the selected server.
Mbps
Upload
How quickly this test sends generated data to the selected server.
ms
HTTP latency
The time for a request and response, including server processing.
ms
HTTP jitter
The average change between consecutive latency samples in this test.
A short sample may be too brief for a useful speed estimate. The tool shows that limitation instead of inventing a number.
How much internet speed do you need?
Start with the busiest hour in your household. List what people need to do at the same time, then check both directions of your package and its conditions.
| Your use | Check before subscribing |
|---|---|
| Everyday browsing | How many devices will be active together? |
| Video calls and study | What upload speed is stated, and is it shared? |
| Streaming and downloads | Are there data limits or traffic-management conditions? |
| Gaming and live sessions | How consistent is the connection to the service you actually use? |
| Shared family connection | What happens when calls, uploads and streaming overlap? |
Before you change your plan
Is it your internet connection or your Wi-Fi?
A wired comparison helps separate the home wireless link from the connection beyond your router. Keep the endpoint and device consistent while you change one condition at a time.
- 01
Check the same endpoint over Ethernet
Use a compatible cable and device. Note whether the issue is repeatable.
- 02
Compare Wi-Fi close to the router
Repeat where you normally use the connection, keeping other transfers paused.
- 03
Keep a useful record for support
Save the endpoint, time, connection type and result. Avoid sharing account passwords or private network details.
Why can a test differ from your package speed?
An advertised package describes a service. This tool measures one browser-to-server transfer at one moment. The device, network path, server and test method all form part of that result.
Your deviceYour connectionSelected endpoint
Compare like-for-like traffic. An Internet endpoint, a BDIX peer and a controlled cache are separate destinations. A result for one does not establish performance to every other service.
Give your home connection a better starting point.
- Check router placement, cable connections and the device you are using.
- Follow your equipment manufacturer’s instructions for updates and restarts.
- Change one condition, repeat the test and keep the result before changing another.
Check before buying a new router.
Compare wired and wireless results and check the existing equipment specifications. A purchase should answer an identified problem.
Should you test with your VPN on?
Record whether a VPN is active when saving your results. If you are diagnosing a difference, compare the same endpoint with and without it only when your workplace or security requirements allow that change.
For work that requires a VPN, the result with it enabled is part of the setup you actually need to assess. Keep that context with the measurement.
Choosing internet for a business?
Use the test as one conversation starter. Ask providers for a written quotation covering your address, concurrent users, upload needs, installation, support hours and outage reporting.
Written service termsSupport and restorationA backup plan
Confirm whether bandwidth is shared or dedicated and what any response-time commitment covers. Published consumer plans are not business quotations.
How this tool works
A real transfer. A clearly stated method.
Press Start Test to begin. It exchanges generated test data with the selected endpoint; it does not upload your personal files.
- Five HTTP latency samples follow one warm-up request. Jitter is the mean change between consecutive samples.
- Small probes select adaptive single-stream samples, capped at 16 MiB download and 8 MiB upload. Very short samples are labelled instead of presented as a useful throughput estimate.
- This is an HTTP check of one endpoint, not a packet-loss measurement or a guarantee of package speed.
- Results stay in this page unless you choose to share a result link or download an image or data copy. The measurement server sees your network address; hosting and proxy logs have their own retention settings.
