Updating Wi-Fi on Your Phone: How to Improve Connection Speed ​​and Stability

Weak Wi-Fi signal, constant connection drops, or slow download speeds on your phone—do you have a familiar problem? Often, the culprit isn't the router's quality, but outdated wireless module drivers, firmware errors, or incorrect network settings. In this article, we'll look at... How to update Wi-Fi on your phone For Android And iOSto restore stable and fast internet.

It is important to understand that “updating Wi-Fi” is not a single universal procedure, but a set of measures. Android-devices can update module firmware and drivers through system settings or manually (for advanced users). Owners iPhone There is only one official method available - update iOS, but there are also hidden settings for network optimization. We'll cover all options, including troubleshooting and alternative solutions if the update doesn't help.

Before you begin, check the basics: is the internet working on other devices, is the router overloaded, and are there any physical obstructions (walls, furniture) between your phone and the signal source? If the problem is limited to one phone, read on.

1. How to check the current Wi-Fi version on Android

Before updating, you need to find out what version of the Wi-Fi driver or firmware is installed on your phone. This will help determine whether an update is required. Android There are several ways:

The easiest way is through settings menu:

1. Open Settings → About phone.
2. Find the item Kernel version or Build number — information about drivers may be displayed here.
3. For detailed information, tap 5-7 times on Build numberto activate Developer mode.
4. Return to Settings → System → Developer Mode and find the section Equipment or Wi-Fi version.

If there is no information about the Wi-Fi module in the menu, use special applications:

• 📱 CPU-Z (tab SoC → Wi-Fi)
• 🔍 DevCheck (chapter Hardware → Wi-Fi)
• 🛠️ AIDA64 (menu Device → Wireless Networks)

In these applications you will see the chip model (for example, Qualcomm WCN3990 or Broadcom BCM4375), driver version and supported standards (Wi-Fi 5, Wi-Fi 6). This data will be useful for searching for updates.

2. Update Wi-Fi via Android system updates

Smartphone manufacturers (Samsung, Xiaomi, Google etc.) regularly release firmware updates that include fixes for wireless modules. To update Wi-Fi on Android:

Open Settings → System → System UpdateIf an update is available, download and install it. Please note:

• 🔄 Updates Wi-Fi drivers often come as part of a general patch package (eg Security Patch).
• 📡 Some manufacturers (eg Samsung) release separate patches for network modules - look for them in the section Downloading updates manually.
• ⚠️ After the update, you may need reset network settings (see section 5).

If the system update did not solve the problem, check module firmware version via the engineering menu (does not work on all models):

##4636##

In the menu that opens, select Wi-Fi Information and compare the version with the latest releases on the forums (for example, 4PDA or XDA Developers).

3. Manually updating Wi-Fi drivers (for advanced users)

If the manufacturer has not released an update, but you know the model of the Wi-Fi chip, you can try install the driver manuallyThis method is suitable for devices with an unlocked bootloader and permissions. root.

Step-by-step instructions:

1. Find out the chip model (see section 1). Popular options: Qualcomm (series WCN39xx, WCN68xx), Broadcom (BCM43xx), Mediatek (MT66xx).
2. Find the latest firmware on thematic forums (for example, XDA) or in the chip manufacturer's repositories.
3. Download the firmware file (usually has the extension .bin or .img).
4. Use ADB or Fastboot for installation:

   adb shell
   su
   dd if=/sdcard/wifi_firmware.bin of=/vendor/firmware/wlan/pronto/wlanmdsp.mbn

5. Restart your phone.

Warnings:

⚠️ Attention! Incorrect firmware of the Wi-Fi module can lead to complete loss of wireless connection or "brick" the device. Before the procedure, create a backup copy of the current firmware using the command:

adb pull /vendor/firmware/wlan/

For devices without root alternative - custom firmware (For example, LineageOS), which often contain updated drivers. Please note that this will void your warranty and require unlocking the bootloader.

What should I do if Wi-Fi doesn't work after a manual update?

If after flashing the module the phone stops seeing networks, try:

1. Restore the original firmware from the backup.

2. Reset network settings in Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth.

3. Check the compatibility of the firmware file with your chip model (the information should be in the file description on the forum).

4. Update Wi-Fi on iPhone (iOS)

On iPhone There are no separate updates for the Wi-Fi module - all fixes come through updates iOSHowever, even after installing the latest version, Wi-Fi issues may persist. Here's what to do:

Step 1: Update iOS:

• 📱 Go to Settings → General → Software Update.
• 🔄 If an update is available, install it. Apple often fixes connection bugs in minor releases (for example, iOS 17.4.1).
• 🔌 Connect your phone to a charger and use Wi-Fi to download the update—this will speed up the update.

Step 2: Reset network settings (if the update did not help):

1. Open Settings → General → Transfer or reset iPhone.
2. Select Reset → Reset network settings.
3. After rebooting, reconnect to Wi-Fi by entering the password.

Step 3: Enable modem data transfer mode (for diagnostics):

If Wi-Fi is unstable, but mobile internet (3G/4G/5G) is stable, the problem may be with the router. Turn it on Modem mode in the settings and connect another device (laptop, tablet) to the phone. If the internet works fine on it, the Wi-Fi module is to blame. iPhone.

⚠️ Attention! On iPhone jailbreak update iOS may result in loss of the jailbreak. Before updating, remove the tweaks via Cydia or Sileo.

5. Optimize Wi-Fi settings to speed up your internet

Sometimes the problem is not in the drivers, but in incorrect network settingsLet's check the key parameters:

On Android:

• 📶 Open Settings → Wi-Fi, tap on your network and select Change network.
• 🔒 Install Security type V WPA2/WPA3 (if the router supports it).
• 🌐 In the section DNS try to specify 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) instead of automatic.
• ⚡ Turn on the option Wi-Fi Performance Mode (available on some devices, such as Samsung Galaxy).

On iOS:

• 📶 Go to Settings → Wi-Fi, tap the "i" icon next to the network.
• 🔄 Turn on Private Wi-Fi address (hides the MAC address from the router).
• 📊 Turn off Low data consumption, if it is active.

For both types of devices:

If the speed has not increased after the changes, check channel congestion using apps like WiFi Analyzer (Android) or AirPort Utility (iOS). It's possible that your neighbors' routers are interfering. In this case, change the channel in your router's settings.

6. Alternative ways to improve Wi-Fi on your phone

If updating drivers and resetting settings did not help, try these methods:

1. Use a signal repeater or mesh system

If the problem is a weak signal (for example, the phone is far from the router), install repeater (For example, TP-Link RE605X) or go to Mesh system (Google Nest Wi-Fi, ASUS ZenWiFi). This will expand the coverage area without losing speed.

2. Connect via USB adapter (Android only)

Some phones (Samsung DeX, devices with OTG) support external Wi-Fi adapters (for example, TP-Link TL-WN725N). This is relevant if the built-in module is damaged. It needs root or a custom kernel.

3. Configure QoS on your router

In the router control panel (192.168.1.1 or 192.168.0.1) find the section QoS (Quality of Service) and set the priority for your phone's traffic MAC addressThis will increase its "weight" on the network.

4. Check your phone for viruses

Some malware (eg. Adware) overload the network stack, which leads to Wi-Fi lag. Scan the device using Malwarebytes or Dr.Web Light.

7. Common Wi-Fi Update Mistakes and How to Avoid Them

Errors when updating drivers or Wi-Fi module firmware can have serious consequences. Let's look at common problems and their solutions:

Error 1: The phone does not see networks after the update

• 🔧 Cause: Incompatible firmware version or corrupted file.
• 🛠️ Solution: Restore the original firmware from a backup or perform a factory reset.

Error 2: Constant connection drops

• 🔧 Cause: Conflict with router settings (for example, enabled WPA3 on an incompatible device).
• 🛠️ Solution: Change the router security type to WPA2-PSK or update your router firmware.

Error 3: Slow speed after update
