How to accurately measure your Wi-Fi router's speed on your smartphone: from apps to hidden settings

Have you noticed YouTube videos are taking a long time to load, or browser pages are loading slowly? The first thing that comes to mind is checking your Wi-Fi speed. But how do you know if the router is to blame or if there's a problem with your smartphone? In this article, we'll look into it. 5 reliable ways Measure your internet speed via your phone, including hidden Android and iOS features that not everyone knows about.

It is important to understand that the speed shown by the router in the web interface and the actual speed on the device are different thingsThe results are affected by the distance to the router, interference from neighboring networks, and even the material of the walls in your apartment. We'll teach you how to distinguish theoretical connection speed (for example, 300 Mbps on the router label) from actual throughput, which yours receives iPhone 15 or Samsung Galaxy S23.

Don't rush to blame your ISP—often the problem lies in the router or phone settings themselves. After reading this, you'll be able to:

• 📱 Measure Wi-Fi speed using standard Android/iOS tools without installing apps
• 🔍 Find out your actual connection speed to your router (not to be confused with internet speed!)
• 📊 Compare results with the standard values ​​for your tariff
• ⚡ Identify bottlenecks, whether it's a weak signal, a congested channel, or outdated router firmware

1. Standard Android tools: where the built-in speed test is hidden

Few people know, but in Android 10 and newer ones have a built-in tool for checking internet speed - without the need to download Speedtest or similar. It's hidden in the menu. Settings → Network & Internet → Wi-Fi.

Instructions for pure Android (on Samsung, Xiaomi or Huawei the path may differ slightly):

1. Open Settings and go to the section Network and Internet.
2. Tap on your Wi-Fi network (not the switch!).
3. In the window that opens, find the item Speed or Network status.
4. The current connection speed will be displayed here. Mbps (updated in real time).

An important nuance: this value shows connection speed to the router, not internet speed! To find out your actual download/upload speed, you need to use specialized services (more on that in the next section).

2. Testing Apps: Speedtest vs. WiFi Analyzer

The most popular way is to use apps like Speedtest by Ookla or WiFi AnalyzerBut there are pitfalls here: these instruments measure Internet speed, not Wi-Fi connection speed. The difference is critical:

• 🌐 Speedtest Shows how fast your phone receives data from the global network (depending on the provider).
• 📶 WiFi Analyzer analyzes signal quality and channel congestion (helps optimize the router).

How to test correctly:

1. Connect to Wi-Fi and close all background applications (especially torrents, cloud syncs).
2. IN Speedtest Select your provider's server (for example, Rostelecom or MTS).
3. Run the test 3 times in a row and take average value - this way you level out random jumps.

Normal results for different tariffs (Mbps):

Disable VPN|Close all applications|Connect to a 5GHz network (if available)|Select your provider's server in Speedtest|Repeat the test 3 times-->

⚠️ Attention: If the speed is in Speedtest It's close to the plan, but the pages are loading slowly. The problem might be with the DNS servers. Try changing them to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) in the router settings.

3. Hidden iPhone Settings: How to See Your Real Wi-Fi Speed

On iPhone There is no built-in speed test, but there is a workaround via Network diagnosticsThis method works on iOS 14 and newer:

1. Open Settings → Wi-Fi.
2. Tap on the symbol i near your network.
3. Scroll down to the block IPv4 ADDRESS.
4. Hold your finger on the field Router and copy the IP address.
5. Paste this address into the Safari browser - this will open the router's web interface, where you can see your connection speed.

An alternative way for advanced users is to use Shortcuts (Labels):

1. Open the app Labels.
2. Create a new shortcut with an action Get network details.
3. Add an action Show notification and select the option Wi-Fi TX/RX (shows the transmission/reception speed in real time).

On iPhone, the speed in the status bar (Wi-Fi icon) is only displayed in the mode Field testing, which is activated through a hidden menu 3001#12345#But this method doesn't work on all models and may reset network settings!

4. Router web interface: where to view the speed of connected devices

If you need accurate connection speed between the router and your phone (not the internet speed), check the router's web interface. To do this:

1. Find out the IP address of the router (usually 192.168.0.1 or 192.168.1.1).
2. Enter it into the address bar of your phone's browser.
3. Log in (default logins: admin/admin or look at the router sticker).
4. Find the section Wireless network (Wireless) → Statistics or Connected devices.

Examples for popular models:

• 🔹 TP-Link: Advanced → Statistics → Wireless
• 🔹 ASUS: Network Map → Clients (the speed is visible there in real time)
• 🔹 Keenetic: Monitoring → Connected Devices

In this menu you will see:

• 📶 Connection speed (For example, 866.7 Mbps For Wi-Fi 5 or 1.2 Gbps For Wi-Fi 6).
• 📊 Signal level (in dBm - the closer to 0, the better).
• 🔄 Connection protocol (802.11ac, 802.11ax, etc.).

⚠️ Attention: If the router statistics show that the connection speed to the phone is significantly lower than the maximum (for example, 150 Mbps instead of 866 Mbps), this is a sign of interference or suboptimal settings. Try changing the Wi-Fi channel to a less crowded one (use WiFi Analyzer for analysis).

5. Professional tools: Termux and NetSpot

For advanced users who need detailed data, the following are suitable:

Termux (Android):

A utility for running Linux commands directly on your phone. Install it from F-Droid (not from Google Play!) and run:

pkg install net-tools
ifconfig wlan0

Find the line in the output RX bytes/TX bytes — this is the amount of data received/transmitted. To calculate the speed, run the command twice, 10 seconds apart, and compare the values.

NetSpot (iOS/Android):

This app not only tests speed but also builds Wi-Fi heat map, showing areas with weak signal. Useful for optimizing router placement. The free version includes basic features:

• 📡 Scans all available networks, indicating the channel and signal strength.
• 📈 Real-time speed change graph.
• 🔍 Detection of interference from neighboring routers.

How to read signal levels in dBm

From -30 dBm to -50 dBm - excellent signal.

From -50 dBm to -60 dBm - a good signal.

From -60 dBm to -70 dBm - satisfactory (some slowdowns are possible).

Below -70 dBm - weak signal, needs optimization.

6. Common Mistakes: Why Tests Show Incorrect Results

Even if you've done everything correctly, your results may be skewed. Common causes:

Problems on the phone side:

• 🔋 Energy saving mode — limits the performance of the Wi-Fi module.
• 📱 Outdated firmware — especially relevant for phones older than 3 years.
• 🔄 Automatic switching between 2.4 GHz and 5 GHz - may lead to speed jumps.

Problems on the router side:

• 📡 Congested channel - if all the neighbors are on the same channel, the speed drops.
• 🔌 Incorrect placement — a router in a closet or behind a TV loses up to 50% of the signal.
• 🛠️ Outdated firmware — especially critical for routers TP-Link Archer C6 or ASUS RT-N12.

External factors:

• 🏢 Thick walls — concrete and metal weaken the signal by 20–30 dBm.
• 🔥 Router overheating — at temperatures above 60°C the speed may drop.
• 🚗 Microwave/Baby Monitor Interference — operate at a frequency of 2.4 GHz.

7. What to do if the speed is lower than expected

If tests show that the speed is too low, follow the algorithm:

Step 1: Check your plan with your provider

Sometimes providers reduce speeds without notice. Check the current terms:

• 📞 Call support (the number is usually on your internet bill).
• 🌐 Log in Personal account on the provider's website.

Step 2: Optimize your router settings

Change the following settings (instructions for TP-Link, ASUS And Keenetic may differ):

• 🔄 Wi-Fi channel: select a fixed channel (eg. 36 for 5 GHz) instead Auto.
• 📶 Channel width: for 5 GHz set 80 MHz (if devices support it).
• 🔒 Security mode: use WPA2-AES (Not TKIP!).
• 🔄 Wi-Fi mode: For modern devices, select 802.11ac or 802.11ax.

Step 3: Update the firmware

Outdated firmware may be limiting speed. Update as follows:

1. Download the latest version from the router manufacturer's official website.
2. Go to the router's web interface (192.168.0.1 or 192.168.1.1).
3. Find the section Administration → Firmware Upgrade.
4. Download the firmware file and wait until it is completed (do not turn off the router!).

⚠️ AttentionYour router settings may reset to factory defaults after updating the firmware. Please write down or take a photo of your current settings (network name, password, channels, etc.) beforehand.

FAQ: Answers to Frequently Asked Questions

Why is the speed on the phone 50 Mbps, but on the computer it is 200 Mbps?

It's normal if:

• 📱 Your phone only supports Wi-Fi 4 (maximum 150 Mbps), and the computer - Wi-Fi 5/6.
• 📶 The phone is connected to the network 2.4 GHz, and the computer is to 5 GHz.
• 🔋 The phone has power saving mode enabled, limiting Wi-Fi performance.

Solution: Connect your phone to the network 5 GHz (if your router supports it) or update your phone to a model with Wi-Fi 5/6.

Is it possible to increase Wi-Fi speed if the provider only provides 100 Mbps?

Yes, but not significantly. Here's what really helps:

• 🔄 Switch from 2.4 GHz on 5 GHz - less interference, more stable connection.
• 📡 Buy a router with support MU-MIMO (For example, ASUS RT-AX88U) - it better distributes the load between devices.
• 🔌 Use a cable instead of Wi-Fi for stationary devices (TV, PC).

But remember: the maximum speed will still not exceed 100 Mbps - this is the provider's limitation.

How do I check my Wi-Fi speed without internet access (for example, on a local network)?

If the Internet is disconnected, but you need to test the speed between your phone and the router:

1. Connect your phone and computer to the same Wi-Fi network.
2. Install on your computer iPerf3 (free utility).
3. Start the server:

   iperf3 -s

4. Install it on your phone iPerf3 from Google Play/App Store and connect to the server.

This will show actual data transfer rate in a local network without dependence on a provider.

Why is the speed so different between cable and Wi-Fi?

A difference of 20-30% is normal due to:

• 📶 Interference on the air (neighboring networks, microwaves).
• 📱 Wi-Fi standard limitations (For example, Wi-Fi 4 the maximum is 150 Mbps, and cable - 1 Gbps).
• 🔋 Distances to the router - every meter and obstacle reduces speed.

A critical difference (for example, 100 Mbps via cable vs. 10 Mbps via Wi-Fi) indicates problems with the router or phone.

Which speed test is the most accurate?

No test is 100% accurate, but here is a reliability rating:

1. Speedtest by Ookla - the most popular, but servers can be overloaded.
2. Fast.com (from Netflix) - shows good speed for streaming.
3. nPerf — tests not only the speed, but also the stability of the connection.
4. Local test via iPerf3 - the most honest, but requires a second device.

To be objective, run 2-3 different tests and take the average value.
