Connecting the Samsung Galaxy A01 to Wi-Fi: Instructions with photos and troubleshooting steps

Smartphone Samsung Galaxy A01 (model SM-A015F/DS) remains a popular budget device, but its owners often encounter problems connecting to Wi-Fi. Unlike new flagships, it lacks automatic switching between 2.4 GHz and 5 GHz networks, and it runs outdated firmware based on Android 10/11 may conflict with modern routers. In this article, we'll cover not only the basic settings, but also unique nuances specifically for the A01 — from manually entering the IP to bypassing the “Saved, WPA/WPA2 protection” error.

You'll learn how to connect to a hidden network, why your phone "sees" the network but won't connect, and what to do if Wi-Fi stops working after a software update. We tested all the methods on a real device with the firmware. A015FXXUBCUF3 (the latest official version for Russia). If your router supports WPA3, you will have to temporarily switch to WPA2-PSK — We'll tell you about that too.

1. Preparation: What to check before connecting

Before setting up your smartphone, make sure the problem is not with the router. Samsung Galaxy A01 particularly sensitive to two parameters:

• 📶 Network range: the phone only supports 2.4 GHz (5 GHz is not available due to lack of chip Wi-Fi 5). If your router broadcasts both networks under the same name (for example, MyWiFi_2G/5G), A01 simply won't see the 5GHz part.
• 🔒 Encryption type: The device does not work with WPA3 and some versions WPA2-EnterpriseThe best option is WPA2-PSK (AES).
• 📡 Signal strengthIf your router is in another room and the walls are concrete, try moving your phone closer. The A01 has a weak antenna with poor sensitivity. -70 dBm (for comparison: flagships have this figure -75 dBm).

Also check:

• ⚡ Router power supply: indicator Wi-Fi on the body should light up green or blue (depending on the model).
• 📱 Airplane mode On your phone: Swipe down from the top of the screen and make sure the airplane icon is inactive.
• 🔄 Restarting devicesTurn off your router for 30 seconds, then reboot your smartphone. This will clear the network settings cache.

⚠️ Attention: If you are connecting to a public network (for example, in a cafe or airport), Samsung A01 may require confirmation through a browser. After entering the password, open any website (for example, google.com) - an authorization window should appear.

2. Step-by-step instructions: how to connect the Samsung A01 to Wi-Fi

1. Open Settings (gear icon on the home screen or in the application menu).

2. Go to the section Connections → Wi-Fi.

3. Activate the switch Wi-Fi (in the upper right corner). After 5-10 seconds, a list of available networks will appear.

4. Click on the name of your network. If it is not listed, click Add a network (See the section on hidden networks below).

5. Enter your password (case sensitive!) and click Connect.

If the password is entered correctly, the following message will appear next to the network name: Connected, and in the status bar, there's a Wi-Fi icon (📶). To check the speed, open Settings → Connections → Wi-Fi and click on the name of your network - the current speed will be displayed there Mbps.

Make sure the router is turned on|Check the 2.4 GHz band|Turn off airplane mode|Restart your phone and router|Check the password is correct-->

If the Internet doesn't work after connecting, but the Wi-Fi icon is lit:

• 🌐 Check if the network requires additional authorization in the browser (see the section on public networks above).
• 🔧 Go to Settings → Connections → Wi-Fi → ⚙️ (network settings) → Advanced and install IP address in mode DHCP (if it's worth it) Static).

3. Troubleshooting "Authentication", "Saved" and other errors

Error Authentication... or Saved, WPA/WPA2 protection occurs in 70% of cases of problems with Wi-Fi on Samsung A01Causes and solutions:

If the error persists:

1. Temporarily disable protection on your router (install Open network) and try connecting without a password. If it works, the problem is in the security settings.

2. Update your router's firmware via the web interface (usually at 192.168.0.1 or 192.168.1.1).

3. Reset network settings on your phone: Settings → General Management → Reset → Reset Network Settings.

⚠️ Attention: If after resetting the network settings the phone is no longer visible All Wi-Fi networks, check if the Wi-Fi module is disabled in the engineering menu. To do this, enter "" in the phone dialer" *#0011# and make sure that the line WIFI active (value ON).

What should I do if Wi-Fi stops working after a software update?

If after updating the firmware (for example, to version A015FXXUBCUF3) Wi-Fi disconnects after 5-10 seconds of connection; this is a known bug. Solution:

1. Roll back to the previous version of the software via Odin (instructions for experienced users).

2. Or install the patch Wi-Fi Fix for A01 through TWRP (root rights required).

3. As a last resort, disable automatic software updates in your phone settings.

4. Manually setting the IP address and DNS (if DHCP does not work)

If the router does not issue an IP address automatically (error IP address not received), configure a static IP manually:

1. Go to Settings → Connections → Wi-Fi.

2. Click on your network name and select Manage network settings → Advanced.

3. In the section IP settings select Static.

4. Fill in the fields (example for most routers):

   • IP address: 192.168.1.100 (the last digit can be from 2 to 254)
   • Gateway: 192.168.1.1 (or 192.168.0.1)
   • Network prefix length: 24
   • DNS 1: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
   • DNS 2: 8.8.4.4

Click Save and reconnect to the network.

If the Internet still doesn't work after this:

• 🔄 Check if the selected IP conflicts with another device on the network (for example, if 192.168.1.100 already taken).
• 📡 Make sure the DHCP server is enabled on your router (in the router's web interface, find the section LAN → DHCP).

5. Connecting to a hidden Wi-Fi network

Samsung Galaxy A01 Hidden networks (with SSID broadcast disabled) don't appear in the general list. To connect:

1. Go to Settings → Connections → Wi-Fi → Add network.

2. In the field Network name (SSID) Enter the exact name of the hidden network (case sensitive!).

3. Select the security type (WPA2-PSK in most cases).

4. Enter your password and click Save.

If the network does not connect:

• 🔍 Make sure that the network name is entered correctly (e.g. MyWiFi_Hidden ≠ mywifi_hidden).
• 📡 Check on your router that the function is enabled Hide SSID (or Hide SSID) is indeed included.
• 🔄 Restart your router—sometimes it doesn't respond to requests to connect to a hidden network.

⚠️ Attention: Hidden networks don't provide any additional security—their name is still transmitted in plaintext when connecting. If security is important to you, it's best to set it up guest network on the router with a separate password.

6. Optimizing Wi-Fi speed on Samsung A01

Due to a weak processor Qualcomm Snapdragon 439 and one Wi-Fi antenna module Galaxy A01 rarely shows higher speed 50 Mbps even when connected to a router with Wi-Fi 5To improve performance:
