How do I run a wifi speed test on Google?
To use Google’s built‑in speed test, simply type “internet speed test” into the Google search bar on your phone or computer. The widget that appears at the top of results runs a quick measurement. It shows your download speed, upload speed, and latency.
The trade‑off: Google’s test is easy but not as detailed as a dedicated app. For a fuller picture, consider using the Ookla Speedtest app (global leader in network testing), which also measures jitter and packet loss.
Steps to use Google’s built-in speed test
- Open any browser and go to google.com.
- Search for “speed test” or “internet speed test”.
- Click the blue “Run Speed Test” button in the widget.
- Wait a few seconds while Google pings a nearby server.
- Review your download and upload speeds and ping value.
What data does Google speed test show?
- Download speed (how fast data reaches your device)
- Upload speed (how fast you can send data)
- Latency (ping) in milliseconds
Why this matters: Google’s test is streamlined, but it doesn’t include jitter or server‑selection options, which can hide variability in your connection. The Bonkers.ie speed test (Irish comparison site) adds jitter as a fourth metric, giving a more complete view.

What is the most accurate wifi speed test?
No single tool claims 100% accuracy, but some are more reliable than others. The biggest factor is server location and whether the test is run over Wi‑Fi or a wired Ethernet connection.
Ookla Speedtest vs Fast.com vs Google
The table below distills the differences.
| Feature | Ookla Speedtest | Fast.com (Netflix) | Google Speed Test |
|---|---|---|---|
| What it measures | Download, upload, ping, jitter, packet loss | Download (and upload via hidden toggle) | Download, upload, ping |
| Server selection | Automatic or manual (thousands of servers worldwide) | Automatic (Netflix CDN servers) | Automatic (M‑Lab servers) |
| Best for | General speed testing and detailed diagnostics | Checking streaming speed on Netflix | Quick, no‑frills check |
| Source | Ookla Speedtest official site | Fast.com, a Netflix tool | Google Search widget (no public documentation available) |
Factors affecting accuracy
- Distance from the test server: farther servers increase latency and reduce reported throughput.
- Wi‑Fi vs Ethernet: Wi‑Fi introduces signal loss and interference.
- Background usage: other devices streaming or downloading skew results.
How ISPs throttle speed tests
Some reports suggest that internet service providers may prioritize traffic from popular speed‑test servers, inflating results. The YouTube analysis (community test of multiple apps) noted that certain tools gave consistently higher speeds than others, hinting at possible prioritization.
The pattern: For the most trustworthy result, run multiple tests at different times using at least two different tools. TestMy.net Ireland (independent crowdsourced platform) offers a good cross‑reference because it aggregates data from many users.
Pro tip: Run a test both on Wi‑Fi and via Ethernet to isolate the bottleneck. Many ISP support pages suggest this step.

How to check internet speed with Eir or Vodafone in Ireland?
Each major Irish ISP provides its own speed test page, usually hosted on its support website. These tools are optimised for the provider’s network and may give results that align more closely with what the ISP expects you to see.
Eir broadband speed test
Eir’s speed test is available at eir.ie/helpandsupport/broadbandspeedtest/ (Eir support page). It uses Ookla technology and measures download speed, upload speed, and line quality. Eir says the test compares your actual speed with the maximum speed your line can technically support.
Vodafone WiFi speed test
Vodafone Ireland offers a speed test on its support page at vodafone.ie/help/speedtest/ (Vodafone Ireland support, ISP tool tailored to its own fibre network). It tests both Wi‑Fi and wired connections and integrates with your account to show historical results.
Virgin Media speed test
Virgin Media Ireland’s speed test at virginmedia.ie (broadband support section) provides diagnostic suggestions after the measurement, such as restarting your router or checking cable connections.
What this means: ISP‑specific tests are convenient, but they may not reflect real‑world performance when you’re visiting a site far from your provider’s servers. Cross‑check with a third‑party tool like TestMy.net (independent speed test aggregator) for a second opinion.
The catch: ISP tests often report speeds that match your plan, but that doesn’t guarantee the same performance for all online activities. Always verify with an independent tool.
Why is my wifi speed slower than expected?
Low test results can stem from many causes. The most common culprits are distance from the router, network congestion, and interference from other electronics.
Common causes of slow wifi
- Distance from router: Signal strength drops significantly after 10–15 metres or through walls.
- Peak‑hour congestion: Evenings see the most usage, and overall ISP capacity may be strained.
- Interference: Microwaves, cordless phones, and neighbouring Wi‑Fi networks all compete for spectrum.
How to test Ethernet vs WiFi
To isolate whether Wi‑Fi is the bottleneck, connect your computer directly to the router with an Ethernet cable and run the same Ookla Speedtest (industry standard). A significantly higher wired speed indicates Wi‑Fi is limiting your connection.
ISP throttling
Some providers may shape traffic during heavy usage periods. Although hard to prove, the Bonkers.ie speed test (Irish price‑comparison platform) notes that running tests at different times can highlight patterns that suggest throttling.
The pattern: If you consistently get lower speeds in the evening, your ISP may be managing bandwidth. Run tests at 8 a.m., 2 p.m., and 9 p.m. to confirm.
How to improve internet speed after a speed test?
Once you’ve identified a speed shortfall, a few practical steps can often recover lost performance without calling your provider.
Router placement
Put your router in a central location, away from walls and large metal objects. If possible, elevate it on a shelf rather than on the floor.
Upgrade your plan
If your test results are consistently below 50 Mbps and you have several devices, consider moving to a higher‑tier plan from your ISP. Compare current deals on Bonkers.ie (Irish broadband price‑comparison service).
Use 5GHz band
Most modern routers broadcast two Wi‑Fi bands. The 5 GHz band offers faster speeds but less range. Connect your devices to the 5 GHz network when near the router.
Reduce connected devices
Disconnect devices you aren’t using. Each active device consumes a slice of your bandwidth, especially during video calls or streaming.
If you run a speed test on an Eir (official speed test) or Virgin Media (ISP diagnostic tool) and see a number close to your plan’s advertised speed, but actual browsing feels slow, the bottleneck is almost certainly Wi‑Fi congestion or a distant server, not your overall connection.
Summary
Running a Wi‑Fi speed test is the first step toward understanding your home internet performance, but the tool you choose and how you use it colour the result. For Irish households on Eir, Vodafone, or Virgin Media, combining an ISP‑specific test with a third‑party tool like TestMy.net (Ireland crowd‑sourced data) gives the most balanced picture. The implication: use wired connections for the truest baseline, test at different hours, and if your Wi‑Fi consistently falls short, shift to 5 GHz or reposition your router. For Eir customers, a sustained gap between the provider’s speed test and your real‑world experience means one thing: call your ISP, because the line speed they promise should match what you get.
Frequently asked questions
Does a WiFi speed test measure internet speed or local network speed?
Most speed tests measure the connection between your device and a remote server — that’s your internet speed. Local network speed (between devices in your home) is not tested.
What is a good ping for online gaming?
A ping under 20 ms is excellent; under 50 ms is good for most games. Values above 100 ms may cause noticeable lag. Irish fibre connections typically offer 10–20 ms.
Can I run a speed test while using a VPN?
Yes, but the result will reflect the speed of the VPN connection, not your base internet. Disable the VPN for an accurate test.
How do I test speed on a smart TV or gaming console?
Go to the device’s network settings and run the built‑in speed test, or use a mobile app on the same Wi‑Fi network as the device.
Does Eir speed test show upload speed as well?
Yes, Eir’s speed test (powered by Ookla) displays both download and upload speeds, plus latency.
What factors affect the accuracy of a speed test?
Server selection, Wi‑Fi interference, background usage, and cable quality all influence results. Testing multiple times with different tools improves accuracy.
How often should I test my WiFi speed for best results?
Once a week under normal usage, and immediately after noticing a problem. Regular testing helps you spot trends.
