How to increase Wi-Fi speed on Android: a complete guide

Slow Internet on a smartphone is annoying: video slows down, sites take forever to load, and online games lag. There can be dozens of reasons - from an overloaded router to incorrect settings Android. But in 90% of cases, the problem can be solved on your own, without the help of specialists.

In this article - 12 proven methods speed up Wi-Fi on Android, including hidden phone settings, router optimization and even hardware solutions. We'll look at why the speed on a phone is often lower than on a computer, and what to do about it. Important: some methods require administrator rights or access to the router control panel - make sure you have a username/password for it.

Let's start with the simplest and end with advanced tricks that Not all users know.

1. Check the real Wi-Fi speed: tests and nuances

Before setting anything up, you need to understand where exactly the connection slows down. The speed on the phone depends on three factors:

• 📶 Router signal strength —the farther the phone, the worse the connection.
• 🖥️ Router settings — channel, bandwidth, Wi-Fi standard.
• 📱 Android limitations — background processes, energy saving, DNS.

First check the speed on your phone and compare with others devices. Use Speedtest from Ookla or nPerf:

1. Connect to the same Wi-Fi network as your phone from a laptop or PC.
2. Run a speed test on both devices at the same time.
3. Compare the results: if the speed on your computer is 2-3 times higher - the problem is in the phone.

If the speed is equally low on all devices, the router or provider is to blame. If only on a phone, read on.

⚠️ Attention: Speed ​​tests may show different results depending on the server. Always select the server closest to you in the application settings.

2. Optimize your router settings for Android

Most routers are configured by default with “universal” settings, which are not always optimal for mobile devices. Here's what you can change:

2.1. Change the Wi-Fi channel

If there are many neighbors in your house with routers, their networks may overlap each othercreating interference. Use the application WiFi Analyzer (or the built-in analyzer in the router) to find the least loaded channel.

How to change the channel:

1. Go to the control panel of the router (usually 192.168.0.1 or 192.168.1.1).
2. Go to Wi-Fi Settings → Channel.
3. Select a channel with minimal load (for example, 6 or 11 for 2.4 GHz).

2.2. Enable 5 GHz mode (if supported)

The network 5 GHz is less loaded and provides higher speed, but has a shorter range. If your phone and router support this band, use it.

How to connect to 5 GHz:

• 🔄 Reboot the router.
• 📱 In the Wi-Fi settings on your phone, select the network marked 5G or 5 GHz.
• 🔐 If there is no network, check if the mode is enabled 5 GHz in the router settings.

⚠️ Attention: Some budget smartphones (for example Redmi 9A or Samsung Galaxy A03) do not support 5 GHz. Check the specifications of your model.

2.3. Adjust the channel width

Channel width affects the maximum speed, but narrow channels (20 MHz) are more stable. For 5 GHz you can set 40 MHz or 80 MHzif there are few other networks nearby.

Range	Recommended channel width	Max. speed (theoretical)
2.4 GHz	20 MHz	up to 150 Mbit/s
5 GHz	40 MHz	up to 400 Mbit/s
5 GHz (Wi-Fi 6)	80 MHz or 160 MHz	up to 2400 Mbit/s

3. Android settings to speed up Wi-Fi

Even if the router is configured perfectly, Android can artificially limit the speed due to energy saving or background processes. Here's what you can do:

3.1. Disable power saving mode

Function Adaptive battery or Energy saving may reduce network performance. Disable it:

1. Go to Settings → Battery.
2. Disable Adaptive battery and Network optimization.
3. In the section Energy saving mode select Disabled.

3.2. Reset network settings

Sometimes system errors interfere with the normal operation of Wi-Fi. Resetting the network will return everything to factory settings:

1. Open Settings → System → Reset.
2. Select Reset Wi-Fi, mobile network and Bluetooth settings.
3. Confirm the action and reboot the phone.

⚠️ Attention: After resetting, you will have to re-enter passwords for all saved Wi-Fi networks.

3.3. Change DNS servers

DNS from your ISP may be slow. Try Google DNS or Cloudflare:

1. Go to Settings → Wi-Fi.
2. Click on your network → Change network → Additionally.
3. In the field DNS enter:

   8.8.8.8, 8.8.4.4

   (Google) or

   1.1.1.1, 1.0.0.1

   (Cloudflare).

4. Advanced methods: for experienced users

If standard methods do not help, try these less obvious tricks:

4.1. Enable developer mode and optimize the network

The developer menu has hidden settings that affect Wi-Fi speed:

1. Activate developer mode: Settings → About phone → Build number (press 7 times).
2. Go back to Settings → System → Developer mode.
3. Find options:
   • Not disable data transfer - enable.
   • Limit background processes — select No restrictions.
   • Wi-Fi debugging —disable if not used.

4.2. Use applications to speed up Wi-Fi

Some utilities help optimize your connection:

• 🚀 Internet Speed Master — clears the DNS cache and optimizes routes.
• 🔧 WiFi Doctor — analyzes the network and suggests improvements.
• 📊 NetMaster — shows detailed traffic statistics.

⚠️ Attention: Do not install applications from unknown sources - they may contain malicious code. Use only Google Play.

4.3. Update the firmware of your phone and router

Outdated software may contain errors that affect speed. Check for updates:

• 📱 On the phone: Settings → System → Software update.
• 🖥️ On the router: usually in the section Administration → Firmware Upgrade.

What to do if Wi-Fi starts working after the update worse?

If after updating the router firmware the speed has dropped, try rolling back to the previous version (if you have a backup) or reset the router to factory settings. On a phone, after updating Android, sometimes resetting the network settings helps (see section 3.2).

5. Hardware solutions: if all else fails

If software methods do not produce results, the problem may be in hardware:

5.1. Buy a repeater or Mesh system

If the router is located far away and the signal is weak - repeater (amplifier) or Mesh system will help expand the coverage area. Popular models:

• 📡 TP-Link RE605X (Wi-Fi 6, up to 1800 Mbit/s).
• 🏠 Xiaomi Mesh System (for large houses).
• 🔄 Asus RP-AX56 (supports AI optimization).

5.2. Change the antennas on the router

If your router supports removable antennas, you can install more powerful ones (for example, TP-Link TL-ANT2408CL with gain 8 dBi). This will increase the range and stability of the signal.

5.3. Use Powerline adapters

If Wi-Fi passes through thick walls, Powerline adapters they transmit the Internet via electrical wiring. For example, TP-Link AV1000 gives speeds up to 1000 Mbit/s without loss.

6. Frequent errors that slow down Wi-Fi

Many users themselves degrade speed, without even knowing it. Here are the most common errors:

• 🔌 The router is in a corner or behind furniture —the signal is blocked by walls and objects.
• 📶 An outdated Wi-Fi standard is used (for example, 802.11n instead 802.11ac/ax).
• 🔄 They do not reboot the router for months —this leads to freezes.
• 📱 Too many background applications are enabledwhich are "stolen" traffic.
• 🔒 You have a weak Wi-Fi password —neighbors can connect and load the network.

Correcting these errors often gives an increase in speed 30-50% without additional settings.

7. Comparison of speed on different versions of Android

Wi-Fi performance may vary depending on the version Android and the manufacturer's shell. Here are the average performance on popular devices (tests were carried out at a distance of 3 m from the router ASUS RT-AX88U):

Device (chipset)	Android	Speed 2.4 GHz (Mbit/s)	Speed 5 GHz (Mbit/s)
Samsung Galaxy S23 (Snapdragon 8 Gen 2)	14	120	850
Xiaomi Redmi Note 12 (Snapdragon 4 Gen 1)	13	95	420
Google Pixel 7 (Tensor G2)	14	130	900
Realme 9 Pro (Snapdragon 695)	12	80	380

As you can see, flagship smartphones (Samsung S23, Pixel 7) show 2 times higher speed. at 5 GHz than budget models. This is due to support Wi-Fi 6/6E and more powerful antennas.

FAQ: Answers to frequently asked questions

Why is Wi-Fi speed lower on a phone than on a computer?

There are several reasons for this:

1. Computers usually have more powerful Wi-Fi adapters (for example, Intel AX200 vs Qualcomm WCN6855 in phones).
2. Android limits the background activity of applications, which can reduce network priority.
3. On a PC, a wired connection (Ethernet) is often used, which is always more stable than Wi-Fi.

Solution: try connecting your phone to 5 GHz, disable power saving and check your DNS settings.

Is it possible to speed up Wi-Fi without access to a router?

Yes, but the options are limited:

• Change DNS on the phone.
• Disable power saving.
• Use applications to optimize the network (for example, Internet Speed Master).
• Reconnect to the network (forget the network and connect again).

However, the maximum effect provides comprehensive setup both the phone and the router.

Does flashing the phone help to speed up Wi-Fi?

Flashing to custom software (for example, LineageOS) can help if:

• Stock firmware contains errors in Wi-Fi drivers.
• The manufacturer artificially limits the speed (rarely, but it happens).

However, risky method: you can lose the warranty or “brick” the phone.

How to check if a neighbor is stealing my Wi-Fi?

There are several ways:

1. Go to the control panel of the router and look at the list of connected devices (DHCP Clients List or Connected Devices).
2. Use applications like Fing or NetCut to scan the network.
3. Check whether the speed drops at certain hours (for example, in the evening, when neighbors are at home).

If you find other people's devices, change the password to a higher one complex (for example WPA3-Personal with 12+ characters).

Is it worth buying a router with Wi-Fi 6 for your phone?

It makes sense if:

• Your phone supports it Wi-Fi 6 (for example, Samsung Galaxy S20+, iPhone 11 and newer).
• You have an Internet tariff from 300 Mbit/s and higher.
• There are many devices in the house connected at the same time (smartphones, TVs, laptops).

For budget phones (for example, Redmi 9 or Samsung A13) Wi-Fi 6 will not give a noticeable increase - they support a maximum of Wi-Fi 5.
