How to connect to the internet via Wi-Fi on a Samsung phone: instructions for all models

Connecting to Wi-Fi on smartphones Samsung It seems like a simple task—until you encounter errors like "Authentication," "Saved, but no internet access," or a complete lack of networks in the list. Even if you've never set up a wireless network before, this guide will help you figure out how to connect on any model—from budget to budget. Galaxy A14 to the flagship Galaxy S24 Ultra.

We won't limit ourselves to the basic "turn on Wi-Fi → select a network → enter a password" scheme. Instead, we'll explore the nuances: what to do if your phone can't see the 5 GHz network, how to connect to a hidden access point, and why IP address not received and how to fix the "No Internet Connection" error even with Wi-Fi enabled. Also, a table of error codes and how to resolve them without resetting the settings.

If you have already tried to connect and received an error, skip the first section and go straight to diagnosing problemsFor beginners, let's start with the basics.

Basic Steps: How to Connect to Wi-Fi on a Samsung

On most phones Samsung The Wi-Fi connection algorithm is the same, but may differ slightly depending on the shell version One UIFor example, on Galaxy S22 With One UI 6.1 the menu looks different than on Galaxy A51 With One UI 4.1However, the key steps remain the same:

1. Activate the Wi-Fi moduleSwipe down from the top of the screen to open the Quick Settings panel. Find the icon Wi-Fi (It usually looks like a fan-shaped antenna) and tap it. If the icon isn't there, tap the pencil icon ("Edit") and add it to the panel.
2. Select a networkOnce Wi-Fi is turned on, your phone will automatically begin scanning for available networks. Tap the name of your network (SSIDIf the network isn't listed, check whether the router is turned on and isn't hidden (more on this in the next section).
3. Enter your passwordWhen you first connect, you'll be asked to enter a security key. Make sure the letter case matches the one on the router sticker (passwords are case-sensitive!). On some models Samsung You can see the entered password by clicking on the eye icon to the right of the field.
4. Confirm connectionAfter entering the password, click "Connect." If everything is successful, "Connected" will appear next to the network name, and a Wi-Fi icon will appear in the status bar.

On phones with One UI 5.0 On devices with newer devices, you may see a notification that says "Internet connection is being checked" after connecting. This is normal—the phone is testing the speed and stability of the connection. If the test takes longer than 30 seconds, there are issues with the router settings (more on that below).

The router is turned on and the Wi-Fi indicator is green/blue.

The phone is within the network coverage area (no further than 10 meters from the router)

The password was entered without typos (check your keyboard layout)

The MAC address filter is not activated on the router-->

If after connecting an exclamation mark appears next to the network name and the Internet does not work, proceed to the section "Wi-Fi is connected, but there is no internet."All possible causes are discussed there, including problems with DHCP and DNS.

Connecting to a hidden Wi-Fi network on Samsung

Some routers (especially in offices or public places) are configured not to broadcast the network name (SSID). In this case Samsung It won't show up in the list of available networks, but you can still connect. Here's how:

1. Open Settings → Connections → Wi-Fi.
2. Scroll down and click "Add a network" (on some models - "Other networks»).
3. In the field "Network name (SSID)» Enter the exact name of the hidden network (check with the administrator or look on the router sticker).
4. Select the security type. Typically this is WPA2/WPA3-PSK (If you are not sure, check with your provider).
5. Enter your password and click "Save».

If after saving the network the phone still does not connect, check:

• 🔄 SSID caseThe network name is case-sensitive: "MyWiFi" and "mywifi" are two different networks.
• 🔒 Security typeIf you select the wrong protocol (for example, WEP instead of WPA2), the connection will fail.
• 📡 Network rangeHidden networks often only operate in the 2.4 GHz band. Try manually specifying the band in the network settings (see the next section).

On phones Samsung With One UI 6.0 and newer when adding a hidden network you can immediately specify static IP address, if required for connection. To do this:

1. After entering the SSID and password, click "Additionally" (or "Advanced settings»).
2. In the section "IP settings» select «Static».
3. Fill in the fields IP address, Gateway, Network mask And DNS (data must be provided by the network administrator).

How to connect to 5GHz Wi-Fi on a Samsung device

Modern routers support two Wi-Fi ranges: 2.4 GHz (long-range but slow) and 5 GHz (fast, but with less coverage). Many phones Samsung Automatically connect to 2.4 GHz even if a 5 GHz network is available. To force the band selection:

1. Open Settings → Connections → Wi-Fi.
2. Tap on the name of your network (already connected or saved).
3. Click "Delete" (or "Forget the network”) to reset the current settings.
4. Select the network from the list again. If your router broadcasts both bands, you'll see two networks with the same name, but with separate labels. 2G or 5G (for example, "MyWiFi_5G"). Select the network marked 5G.
5. Enter the password and connect.

If the 5GHz network is not listed, the reasons may be as follows:

• 📶 The router does not support 5 GHz.. Check the router model - budget devices (for example, TP-Link TL-WR840N) often operate only in the 2.4 GHz range.
• ⚙️ The range is disabled in the router settings.Go to your router's control panel and enable 5 GHz broadcasting.
• 📱 The phone does not support 5 GHzThis is relevant for very old models. Samsung (For example, Galaxy J2 2016).
• 🔄 Automatic range selectionSome routers (for example, ASUS RT-AX88U) combine 2.4 and 5 GHz networks under a single SSID. In this case, the phone automatically selects the band, and there's no forced switching.

2.4 GHz only

5 GHz only

Both ranges (automatic selection)

I don't know what this is-->

If your Samsung If you can't see the 5 GHz network, but your router supports it, try the following:

1. Reboot your router (unplug it from the power outlet for 30 seconds).
2. Change the router settings 5 GHz channel to a fixed one (for example, 36 or 48) instead of “Auto”.
3. Update your router's firmware (instructions are usually available on the manufacturer's website).

⚠️ Note: In some countries (such as Russia), channel restrictions apply to the 5 GHz band. If your router is set to a channel not supported in your region (e.g., 149–165), your phone will not see the network. Check the channel settings in the router control panel.

Wi-Fi is connected, but there is no internet: what to do

One of the most common problems is when a phone connects to Wi-Fi, but pages won't open, and an exclamation point appears next to the network name. The causes could be either phone- or router-related. Let's look at each one.

1. DHCP issues (IP address not received)

If in your network settings you see an IP address like 169.254.x.x or 0.0.0.0, which means the phone couldn't get an address from the router. This can be fixed as follows:

• 🔄 Reconnect to the networkForget the network (Wi-Fi settings → tap on network → Delete), then reconnect.
• ⚙️ Set up a static IP:
  1. In the Wi-Fi settings, tap on the network name → "Change network» → «Additionally».
  2. In the section "IP settings» select «Static».
  3. Enter:
     • IP address: 192.168.1.X (where X is a number from 2 to 254, not occupied by other devices).
     • Gateway: 192.168.1.1 (or 192.168.0.1 - look at the router sticker).
     • Network mask: 255.255.255.0.
     • DNS 1: 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS).

2. DNS issues

If the IP address is received (for example, 192.168.1.100), but websites won't open, the problem might be DNS. Try:

• 🌐 Change DNS manually:
  1. In the network settings, select "Additionally» → «IP settings» → «Static».
  2. Into the fields DNS 1 And DNS 2 enter:
     • 8.8.8.8 and 8.8.4.4 (Google DNS),
     • or 1.1.1.1 and 1.0.0.1 (Cloudflare DNS).

3. Authentication errors or MAC address blocking

If the error "Authentication" or "Saved, but without internet", Maybe:

• 🔑 Incorrect password. Delete the network and re-enter the password (check the case!).
• 🚫 MAC address filteringSome routers only allow devices with specific MAC addresses to connect. Check your router settings in the "MAC filter" or "Access control».
• 🔄 Incompatible security typeIf the router is configured to WPA3, and your phone doesn't support it, try changing the security type to WPA2-PSK in the router settings.

⚠️ Attention: If after all these steps the internet still doesn't work, check if it's blocked antivirus or VPNDisable them temporarily. Also, make sure your provider has sufficient funds—sometimes access is blocked for non-payment.

Troubleshooting: Why won't my Samsung connect to Wi-Fi?

If your phone can't find a network at all or constantly loses connection, the cause could be software or hardware. Let's look at the most common scenarios.

1. The phone doesn't see any Wi-Fi networks.

If the list of available networks is empty, check:

• 📶 Is Wi-Fi enabled?Sometimes the module is disabled after an update or reset.
• ⚙️ Airplane mode. Make sure it is turned off (Settings → Connections → Airplane Mode).
• 🔧 Hardware failureIf Wi-Fi doesn't work even after a factory reset, the Wi-Fi module may be faulty. This is especially true for phones that have been dropped or exposed to water.
• 📱 Software updateOn some models Samsung (For example, Galaxy Note 20) after updating to Android 14 There were problems with Wi-Fi. Check for updates in Settings → Software Update.

If networks aren't visible only in a specific location (like at home), but are visible in a cafe or office, the problem is most likely with the router. Try:

• Change Wi-Fi channel in the router settings (for example, from “Auto” to 6 or 11 for 2.4 GHz).
• Disable the "Smart Wi-Fi" or "Band Steering" (it may interfere with the connection).
• Update the router firmware.

2. Wi-Fi keeps disconnecting

If your phone disconnects spontaneously, there may be the following reasons:

• ⚡ Battery savingWi-Fi optimization mode may be enabled in battery settings. Disable it:
  1. Go to Settings → Device Maintenance → Battery.
  2. Tap the three dots in the upper right corner → «Battery settings».
  3. Find "Adaptive battery" or "Optimizing Wi-Fi performance" and turn it off.

Settings → General → Reset → Reset network settings

3. Error: "Saved, but no internet access"

This error occurs when the phone connects to the router, but it doesn't provide internet access. Causes:

• 🌍 Problems with the providerCheck if the internet works on other devices.
• 🔌 Router malfunction. Reboot it and check the indicators (Internet port).
• ⚙️ Incorrect router settings. Make sure that the correct connection type is specified in the WAN settings (usually DHCP or PPPoE).
• 🔒 Parental controlIn some routers (for example, Keenetic) you can block internet access for certain devices by MAC address.

If the problem is only on your phone and other devices are working fine:

1. Delete the network and reconnect.
2. Set up a static DNS (e.g. 8.8.8.8).
3. Reset network settings on your phone (Settings → General → Reset → Reset network settings).

Advanced Wi-Fi settings on Samsung

If basic methods don't help, you can try more advanced settings. These are useful if you're connecting to a corporate network, public Wi-Fi with a captive portal, or setting up roaming between multiple access points.

1. Setting up a proxy server

Some networks (such as hotels or universities) require a proxy to access the internet. To set it up, Samsung:

1. Open Settings → Connections → Wi-Fi.
2. Tap on the network name → «Change network» → «Additionally».
3. In the section "Proxy» select «Manually».
4. Enter the proxy address (for example, proxy.example.com) and port (for example, 8080).
5. Save settings and reconnect.

2. Connecting to a network with an authorization portal

It is often used in airports, cafes and hotels. captive portal — a page where you need to enter your login/password or accept the terms and conditions. If this page doesn't open automatically after connecting to Wi-Fi:

1. Open your browser and try to access any website (for example, google.com).
2. If an authorization page opens instead of the website, enter the required information.
3. If the page doesn't open, manually enter the portal address. Typically, it's:
   • 1.1.1.1
   • neverssl.com
   • captive.apple.com (also works on Android)

3. Setting network priority

If your phone automatically connects to a slow network (for example, 2.4 GHz instead of 5 GHz), you can set the priority manually:

1. Open Settings → Connections → Wi-Fi.
2. Tap on the network name → «Change network» → «Additionally».
3. Turn on the option "Auto-connection" (if it is disabled).
4. Some firmwares have an option "Network priority" - set it to the maximum value.

4. Diagnostics via the engineering menu

If Wi-Fi doesn't work at all, you can check the module's hardware status through the engineering menu. This method is only suitable for experienced users - incorrect actions may lead to system failure.

1. Open the app "Telephone» and enter the code:

   *#0011#

2. In the menu that opens, select "Wi-Fi».
3. Check the module status. If the line "Wi-Fi status" indicated "Off", it means that the module is disabled or faulty.
4. To exit, press the "Menu» → «Back».
