1. Checking your actual speed: how to figure out who's to blame for the brakes

Before you set anything up, you need to diagnose the problem more accuratelySlow Wi-Fi on your phone can be caused by:

  • 📶 Weak router signal (for example, you are at the edge of the coverage area).
  • 🖥️ Channel overload (neighbors use the same channel 2.4 GHz).
  • 📱 Phone limitations (background processes, battery saving, outdated firmware).
  • 🌐 Problems with the provider (breaks, speed limit according to tariff).

To separate the wheat from the chaff, follow these 3 simple tests:

  1. Measure your speed on your phone through Speedtest or FAST.comRun the test 2-3 times and record the average value. Important: Disable VPN and background downloads (such as app updates).

  2. Check the speed on another device (laptop, tablet) on the same network. If the speed is normal there, the problem is with the phone. If it's still slow, the router or ISP is to blame.

  3. Connect your phone to mobile Internet (4G/5G) And measure the speed again. If it's higher than the Wi-Fi speed, the problem is with the wireless network.

If the speed on your phone is lower than on other devices, proceed to smartphone settingsIf the problem occurs on all devices, read about router optimization.

2. 3 Quick Ways to Speed ​​Up Wi-Fi on Your Phone (in 1–2 Minutes)

These methods don't require advanced knowledge and work 70% of the time. Start with them before digging into your router settings.

2.1. Restarting the router and phone

Trivial, but effective: 9 out of 10 Wi-Fi problems are solved by rebooting.A router, like a phone, can freeze due to prolonged operation, especially if it is a budget one (for example, TP-Link TL-WR840N).

  • Turn off the router from the socket for 30 seconds, then plug it back in.
  • 📱 Restart your phone (not just turn off/on the screen, but a full reboot).
  • 🔄 Forget the Wi-Fi network on your phone and reconnect (enter the password manually).

2.2. Disabling background processes

Apps like YouTube, Netflix or TikTok can consume traffic secretly, even when you're not using them. For example, auto-updating apps in Google Play or upload media to VKontakte.

How to stop:

  • 🛑 Android: go to Settings → Applications → Startup and disable background activity for unnecessary programs.
  • 🍎 iPhone: Settings → General → Content Update and turn off the option for applications that should not run in the background.
  • 📥 Disable auto-update of apps V App Store or Google Play.

2.3. Changing Wi-Fi frequency (2.4 GHz → 5 GHz)

If your router supports 5 GHz, but the phone is connected to 2.4 GHz, you lose up to 70% of the speed. Frequency 2.4 GHz overloaded (especially in apartment buildings), and 5 GHz provides greater throughput.

How to switch:

  • 🔍 Check the name of your Wi-Fi network. If there are two networks with the same name but with suffixes _5G or -5GHz - connect to it.
  • ⚙️ If there is no such network, go to the router settings (usually 192.168.0.1 or 192.168.1.1) and turn it on 5 GHz manually.

3. Router Optimization: Settings for Maximum Speed

If quick fixes don't work, it's time to dig deeper. 80% of Wi-Fi problems on your phone can be solved by adjusting your router settings., not a smartphone. Here's what you need to do:

3.1. Selecting the optimal Wi-Fi channel

On frequency 2.4 GHz There are only 13 channels, and in an apartment building they are as congested as the Moscow metro during rush hour. If your router is on a channel 6, and the neighbors too 6, the speed drops by 5-10 times.

How to find a free channel:

  1. Download the app WiFi Analyzer (Android) or NetSpot (iOS).
  2. Run a scan and the program will show you which channels are busy.
  3. Enter your router settings (192.168.0.1 or 192.168.1.1) and manually set the least loaded channel (for example, 1, 11 or 13).
Which channels are best not to use?

Channels 6–8 are usually the busiest, as many routers set them to "Auto" mode by default. Also, avoid channels that overlap with adjacent channels (for example, channel 5 overlaps with channels 4 and 6).

3.2. Updating the router firmware

Outdated firmware may limit the speed due to bugs or lack of support for modern standards (Wi-Fi 6, 802.11ac). For example, a router ASUS RT-AC68U After updating the firmware, it shows a speed increase of up to +40%.

How to update:

  1. Go to your router's control panel (usually at 192.168.1.1).
  2. Find the section Software update or Firmware Update.
  3. Download the latest version from the manufacturer's website (for example, tp-link.com For TP-Link) and download it manually.
⚠️ Attention: Don't update the firmware over the air (via the internet)—this can brick the router. Always download the file from the official website and upload it manually.

3.3. Enabling the Wi-Fi 6 (802.11ax) standard

If you have a modern router (for example, TP-Link Archer AX6000 or ASUS RT-AX88U) and a phone no older than 2020, inclusion Wi-Fi 6 can increase speed by 30-50%. This standard supports:

  • 📶 OFDMA - better distributes traffic between devices.
  • 🔄 MU-MIMO — allows the router to communicate with multiple devices simultaneously.
  • 🛡️ WPA3 - a more secure encryption protocol (does not slow down speed).

How to enable:

  1. Go to your router settings.
  2. Find the section Wireless network or Wireless.
  3. Set the mode 802.11ax (or Wi-Fi 6).
  4. Save the settings and reboot the router.
Wi-Fi standard Max. speed Phone support Advantages
802.11n (Wi-Fi 4) 600 Mbps All smartphones Wide compatibility
802.11ac (Wi-Fi 5) 3.5 Gbps Since 2015 High speed at 5 GHz
802.11ax (Wi-Fi 6) 9.6 Gbps Since 2020 OFDMA, MU-MIMO, better in multi-user mode

4. Phone settings to speed up Wi-Fi

Even if the router is configured perfectly, the phone may artificially limit speed because of:

  • 🔋 Battery saving mode (limits background activity).
  • 📥 Automatic app updates.
  • 🛡️ VPN or proxy (may slow down traffic).
  • 📡 Non-optimal Wi-Fi settings (for example, enabled Wi-Fi Assist on iPhone).

4.1. Disabling power saving mode

On Android And iOS battery saving mode can reduce internet speed by 30–50%. For example, on Samsung Galaxy it limits background activity, and iPhone - reduces processor performance.

How to disable:

  • 📱 Android: Settings → Device Care → Battery → Power Saving Mode (turn off).
  • 🍎 iPhone: Settings → Battery and turn it off Low power mode.

4.2. Configuring Wi-Fi settings on Android

On Android There are hidden settings that can speed up your Wi-Fi:

  1. Enable Developer Mode:

    • Go to Settings → About phone → Build number.
    • Click on Build number 7 times until the message "You are now a developer" appears.
  • Optimize your Wi-Fi settings:

    • Go to Settings → System → Developer options.
    • Find the option Keep Wi-Fi connected when going into sleep mode and select Always.
    • Turn on Aggressive Wi-Fi to mobile network switching (if any).
    • ⚠️ Attention: Enabling the mode Keep Wi-Fi connected when going into sleep mode will increase battery life by 5-10%. Use this trick only if speed is critical.

      4.3. Disabling Wi-Fi Assist on iPhone

      Function Wi-Fi Assist on iPhone Automatically switches to mobile data if the Wi-Fi signal is weak. The problem is that it triggers even with minor speed drops, resulting in data throttling.

      How to disable:

      1. Go to Settings → Cellular.
      2. Scroll down and find Wi-Fi Assist.
      3. Disable the slider.

      2. Click on i near your network.
      3. In the section DNS enter 1.1.1.1, 1.0.0.1.
  • 5.2 Using a Mesh Network or Repeater

    If the problem is weak signal (for example, the router is in one room and the phone is in another), Mesh system or repeater (repeater) can increase the speed by 2-3 times. For example, TP-Link Deco or ASUS ZenWiFi automatically switch devices between nodes, ensuring a stable signal.

    How to choose:

    • 🏠 Enough for an apartment up to 100 m² one repeater (For example, TP-Link RE605X).
    • 🏢 For a house of 150+ m² it’s better Mesh system (For example, Netgear Orbi).
    • 💰 Budget option: configure your old router as a repeater (mode WDS or Repeater).
    • 5.3. Configuring QoS on a router

      QoS (Quality of Service) allows you to prioritize your phone's traffic so it always gets the maximum speed. For example, if someone is watching Netflix on TV, and you urgently need to download a file, QoS will give priority to your phone.

      How to set up:

      1. Go to your router control panel.
      2. Find the section QoS or Traffic priority.
      3. Add your phone's MAC address to the list of priority devices.
      4. Set the maximum bandwidth for your device.
    ⚠️ Attention: QoS settings may reduce speeds for other devices on the network. Use them only if maximum speed on your phone is critical.

    6. Hardware solutions: when nothing helps

    If you have tried all software methods and your phone's Wi-Fi is still slow, the problem may be iron:

    • 📡 Old router (For example, TP-Link TL-WR740N 2012) does not support modern standards.
    • 📱 Problems with the phone antenna (for example, after a fall).
    • 🔌 Bad cable from the provider (damaged or of poor quality).

    6.1. Replacing the router with a more powerful one

    If your router is older than 5 years, it most likely does not support Wi-Fi 5/6 and limited by speed 300 MbpsModern models like ASUS RT-AX86U or TP-Link Archer AX73 give up to 5400 Mbps and support 160 MHz channels.

    What to look for when choosing:

    Characteristic Minimum requirement Recommended value
    Wi-Fi standard 802.11ac (Wi-Fi 5) 802.11ax (Wi-Fi 6)
    5 GHz frequency Eat Support 160 MHz
    Number of antennas 2 4+ (for MU-MIMO)
    CPU Dual-core Quad-core (eg Broadcom BCM4908)

    6.2. Checking the phone antenna

    If your phone has poor Wi-Fi reception even near the router, it is possible hardware failure:

    • 📱 Check if the antenna is damaged (for example, after being dropped or exposed to moisture).
    • 🔍 Compare the speed with another phone of the same model - if the difference is significant, the problem is with your device.
    • 🛠️ If your phone is under warranty, contact a service center. If not, antenna repair will cost 1,000–3,000 rubles.
    • 6.3. Replacing the cable from the provider

      Damaged or low-quality cable (eg. UTP Cat.5 instead of Cat.5e) can cut speeds to 100 Mbps, even if the plan is for 1 Gbps. How to check:

      1. Connect the cable directly to the computer (bypassing the router) and measure the speed.
      2. If the speed is lower than what the provider claims, replace the cable. Cat.6 or Cat.6a.
      3. Check the connectors RJ-45 - they must be crimped correctly (all 8 wires).

      FAQ: Frequently asked questions about slow Wi-Fi on your phone

      ❓ Why is the speed on my phone slower than on my computer?

      There are several reasons:

      1. Different Wi-Fi standards: the computer can support Wi-Fi 6, and the phone is only Wi-Fi 5.
      2. OS limitations: Android And iOS may artificially limit speed to save battery.
      3. Background processes: your phone may be running apps that consume traffic (updates, cloud backups).
      4. Antennas: Laptops usually have more powerful antennas than smartphones.

      Solution: Check your phone settings (turn off battery saving, switch to 5 GHz) and compare speed on different devices.

      ❓ How do I know if my phone supports Wi-Fi 6?

      Verification methods:

      • 📄 Take a look model characteristics on the manufacturer's website (for example, GSMArena).
      • 📱 On Android: go to Settings → Wi-Fi, click on your network and look at the protocol (for example, 802.11ax - this is Wi-Fi 6).
      • 🍎 On iPhone: all models with A12 Bionic and newer (iPhone XS and above) support Wi-Fi 6.

      If your phone does not support Wi-Fi 6, the maximum speed will be limited by the standard Wi-Fi 5 (up to 3.5 Gbps).

      ❓ Why does the Wi-Fi slow down only in the evening?

      This is a problem for apartment buildings. In the evening, all the neighbors actively use the internet, and the channels 2.4 GHz are overloaded. Solutions:

      • 🔄 Switch to 5 GHz (there is less interference).
      • 📡 Change the channel on your router (use WiFi Analyzer, to find a free one).
      • 🕒 Set up QoS on your router to prioritize your phone's traffic.
      • 📶 If your router is old, replace it with a model that supports it. Wi-Fi 6 And MU-MIMO.

      Also check if your ISP limits your speed during peak hours (this is called throttling). Measure your speed during the day and evening. If the difference is more than 30%, contact support.

      ❓ Can a case affect Wi-Fi speed?

      Yes, but only if he:

      • 🧲 Contains metal elements (for example, magnetic clasps or inserts).
      • 🛡️ Very thick (for example, armor
