Slow Wi-Fi on your phone is annoying: videos lag, websites take forever to load, and online games lag. The causes can lie in both your smartphone settings and your router settings—and most often, the problem can be solved without buying new equipment. In this article, we'll look at how. 10 Proven Ways to Speed Up Wi-Fi on Android And iPhone, from basic to advanced, with explanations for users of all levels.
It's important to understand: connection speed depends on the chain "router → transmission medium → phone." We will analyze each element of this chain so that you can pinpoint the bottleneck and eliminate it without unnecessary actions. For example, if your Samsung Galaxy S23 If your phone shows 50 Mbps, but the laptop next to it shows 300 Mbps, the problem is definitely with your phone. Conversely, if all your devices are slow, the router or ISP is to blame.
Let's start with simple solutions that take less than a minute and gradually move on to more complex settings. For your convenience, we've compiled answers to frequently asked questions at the end of the article - there you will find solutions for specific cases, for example, how to speed up Wi-Fi on Xiaomi with custom firmware or why iPhone 15 "cuts" the speed when connected to 5 GHz.
1. Restart your router and phone
It's trivial, but it works in 30% of cases. Routers, especially budget models (TP-Link Archer C50, D-Link DIR-615), sometimes freezing due to overheating or firmware errors. The phone can also become glitchy after prolonged use, especially if dozens of apps are running in the background.
How to reboot correctly:
- 🔌 Router: unplug the power cord for 30 seconds (don't just press the button)
Reset!). This will flush the DHCP cache and clear the routing table. - 📱 Telephone: Hold the power button until the "Power off" menu appears, then turn it on after 20 seconds. iPhone With Face ID Press and hold the side button + any of the volume controls.
- 🔄 Additionally: If the speed hasn't increased after rebooting, try
forget the networkon your phone and reconnect (instructions below).
Why does this help? When running for a long time, the router accumulates "junk" connections (for example, from old devices), and the phone may become stuck on a slow DNS. A reboot resets these settings to factory defaults.
2. Check your current speed and compare it with your tariff
Before messing with your settings, make sure the problem is with your Wi-Fi and not your ISP. To do this:
- Connect your phone to the router via Wi-Fi.
- Run a speed test on Speedtest or FAST.com (from Netflix).
- Compare the result with the speed stated in your tariff (see your provider's personal account).
Critical indicators:
- ⚡ If the speed less than 10% of the tariff (for example, 5 Mbps with a 50 Mbps plan) - the problem is with your provider. Call support.
- 📶 If the speed 20–50% of the tariff — the router or phone settings are to blame.
- 📱 If the speed is normal on other devices, but slow on your phone, read the sections on smartphone settings.
| Device | Wi-Fi speed (5 GHz) | Wi-Fi speed (2.4 GHz) |
|---|---|---|
| iPhone 15 Pro | up to 1200 Mbps | up to 300 Mbit/s |
| Samsung Galaxy S24 Ultra | up to 2400 Mbps (Wi-Fi 6E) | up to 600 Mbps |
| Xiaomi Redmi Note 12 | up to 867 Mbps | up to 150 Mbit/s |
| Router TP-Link Archer AX6000 | up to 4804 Mbps | up to 1148 Mbps |
Please note: If your phone supports Wi-Fi 6 (802.11ax), but if your router is older than 2019, you won't get the maximum speed. For example, iPhone 13 on the router ASUS RT-AC66U (Wi-Fi 5) will be limited to 867 Mbps instead of the potential 1200 Mbps.
3. Change the Wi-Fi channel and frequency (2.4 GHz vs. 5 GHz)
The most common reason for slow Wi-Fi is channel congestionIn apartment buildings, neighbors' routers create interference, especially at frequencies 2.4 GHz, where there are only 3 non-overlapping channels (1, 6, 11). At 5 GHz there are more channels, but the signal range is shorter.
How to choose the optimal channel:
- Download a Wi-Fi analyzer app to your phone:
- 📱 Android: WiFi Analyzer
- 🍎 iPhone: Wi-Fi SweetSpots
192.168.0.1 or 192.168.1.1) and change the channel to the least loaded one.Examples of optimal settings:
- 📡 2.4 GHz: select a channel
1,6or11(they do not intersect). The channel width is20 MHz(not 40 MHz!). - 🚀 5 GHz: use channels
36–48or149–165(allowed in Russia). Channel width -40 MHzor80 MHz(if devices support it).
If your router supports Wi-Fi 6 (802.11ax), turn on the mode AX or Wi-Fi 6 in the settings. This will reduce latency (ping) and increase speed when connecting multiple devices.
How do you know if your router supports Wi-Fi 6?
Look at the device's body—it should say "Wi-Fi 6," "AX," or "802.11ax." Also, check the model's specifications on the manufacturer's website. For example, routers TP-Link Archer AX10, ASUS RT-AX55 and newer support Wi-Fi 6.
4. Optimize your phone's Wi-Fi settings
Even if your router is configured perfectly, your phone may be artificially limiting your speed. Let's look at the key settings for Android And iOS.
For Android:
- 🔧 Turn on developer mode (click 7 times on "Build number" in
Settings → About phone) and activate the optionDo not turn off data transferVDeveloper settings → Networks. - 📶 Turn off
Adaptive Wi-FiorIntelligent switching(on Samsung, Xiaomi). This feature automatically switches the phone to mobile data if Wi-Fi "seems" slow, but it often fails. - 🔄 In

For iPhone (iOS 17+):
- 🔄 Go to
Settings → Wi-Fi, click on the ⓘ icon next to your network and turn it onPrivate Wi-Fi address(this does not affect speed, but improves stability). - 📱 Turn off
Low data consumption modeVSettings → Wi-Fi → [your network]. - 🔧 Reset network settings:
Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
On some phones (eg. OnePlus, Realme) there is a hidden option Wi-Fi+, which combines Wi-Fi and mobile data to speed up downloads. To enable it:
Settings → Wi-Fi & networks → Advanced → Wi-Fi+
Battery saving mode is disabled
Developer mode is enabled (for Android)
Reset network settings (if speed is not restored)
Smart switches between Wi-Fi and mobile data are disabled-->
5. Update your router firmware and phone software
Outdated router firmware may limit speed due to bugs or lack of support for new standards (for example, Wi-Fi 6). The same applies to the phone: in the latest versions Android And iOS often optimize work with networks.
How to update your router:
- Go to the router's web interface (usually
192.168.0.1or192.168.1.1). - Find the section
Software updateorFirmware Update. - Download the latest firmware from the manufacturer's website (for example, for ASUS — support.asus.com) and download it manually.
How to update your phone:
- 📱 Android:
Settings → System → System Update. - 🍎 iPhone:
Settings → General → Software Update.
After updating the router Be sure to reset its settings (button Reset on the back panel) and reconfigure. This will eliminate conflicts between the old and new settings.
6. Use a Mesh system or repeater (if the signal is weak)
If the problem is weak signal (For example, if your phone shows 1-2 Wi-Fi bars), no setting will help—you'll need signal-boosting equipment. Options:
Mesh system (For example, TP-Link Deco, Google Nest Wi-Fi):
- 🏠 Ideal for large apartments or houses with thick walls.
- 🔄 Automatically switches devices between nodes, ensuring maximum speed.
- 💰 Cost: from 5,000 ₽ for a set of 2–3 points.
Wi-Fi repeater (For example, Xiaomi Wi-Fi Repeater 2):
- 📶 Boosts the signal in a specific area (for example, in a distant room).
- ⚠️ Reduces speed by 30-50% due to double data transfer.
- 💰 Cost: from 1,500 ₽.
Powerline adapter (For example, TP-Link AV1000):
- 🔌 Transmits internet through electrical wiring—useful if the router and phone are in different rooms.
- 📶 Speed: up to 1000 Mbps (actually ~300–500 Mbps).
Please check your router before purchasing. bridge mode (WDS) or AiMesh (at ASUS). This will allow you to combine several routers into one network without losing speed.
7. Disable background apps and VPN
Many programs consume traffic in the background: cloud backups (Google Photos, iCloud), application updates, instant messengers with automatic media downloads. A VPN may reduce speed by 20-70% due to encryption and remote servers.
How to free up traffic:
- 🛑 Android: Go to
Settings → Apps → Permissions → Autostartand disable autostart for unnecessary programs. Also inSettings → Battery → Battery optimizationselectDo not optimizefor critical applications (e.g. instant messengers). - 🍎 iPhone: IN
Settings → General → Content UpdateDisable background refresh for unnecessary apps. - 🔒 VPN: Disable VPN in settings or uninstall the app (for example, NordVPN, ProtonVPN). If you need a VPN, select a server in your country or the closest one geographically.
Check which apps are consuming traffic:
- 📊 Android:
Settings → Networks & Internet → Data Usage → Wi-Fi Data Usage. - 📊 iPhone:
Settings → Cellular → Statistics(shows Wi-Fi traffic as well).
If you use Torrent clients (For example, uTorrent, qBittorrent), limit the download/upload speed in the program settings - otherwise they will "eat up" the entire channel.
8. Check the QoS settings on your router
QoS (Quality of Service) — This is a router feature that prioritizes traffic between devices. If it's configured incorrectly, your phone may receive minimal speed, while your laptop or Smart TV may hog all the bandwidth.
How to set up QoS:
- Go to your router settings (usually
192.168.0.1). - Find the section
QoS,Traffic priorityorBandwidth Control. - Disable QoS or configure priorities manually:
- 🎮 For games: set the highest priority for
UDP port 3074(PlayStation),27000–27030(Steam). - 📺 For streaming: priority for
Netflix,YouTube,Twitch. - 📱 For your phone: Add its MAC address to the list of high-priority devices.
- 🎮 For games: set the highest priority for
If you are unsure about the settings, just disable QoS — in most cases, this increases overall speed, since the router does not waste resources on traffic analysis.
On some routers (ASUS, Netgear) there is a mode Adaptive QoS — it automatically prioritizes. Try enabling it if manual settings don't help.

FAQ: Answers to Frequently Asked Questions
Why is Wi-Fi speed slower on iPhone than on Android?
iPhone Artificially limits speed on some routers due to compatibility issues. Solutions:
- Turn on the router mode
802.11n/ac/ax(not only802.11ac). - Turn it off
802.11r (Fast Roaming)in the router settings. - Update iOS to the latest version.
If nothing helps, try connecting to a 5 GHz network - it iPhone usually works faster.
How to speed up Wi-Fi on a Xiaomi phone running a custom ROM (like Pixel Experience)?
Unofficial firmware often lacks Wi-Fi drivers. Try this:
- Install Wi-Fi 6-enabled core (For example, FrancoKernel For Xiaomi).
- Turn on
Wi-Fi Callingin the SIM card settings - this sometimes stabilizes the connection. - Roll back to the official firmware MIUI, if speed is critical.
Does replacing antennas on a router help?
Yes, but only if:
- Your router has removable antennas (For example, ASUS RT-AC86U).
- You buy antennas with gain of 5–9 dBi (For example, TP-Link TL-ANT2409A).
- The problem is precisely in weak signal, and not in the channel load.
Expected increase: +10–20% speed at a large distance from the router.
Why does the speed drop in the evening?
In the evening, provider networks are overloaded due to the influx of users. What to do:
- Call your provider and ask to transfer you to less loaded server (some operators provide this option).
- Use DNS from Google (
8.8.8.8) or Cloudflare (1.1.1.1) - this sometimes speeds up website loading. - Turn it on on your router

How can I check if my neighbor is stealing my Wi-Fi?
Download the app Fing (Android/iOS) and scan the network. If you find any unknown devices:
- Change your Wi-Fi password to a complex one (at least 12 characters with numbers and special characters).
- Enable it in your router settings
MAC address filteringand add only your devices. - Turn it off
