Luckily, protect the network with a password you can do it directly from your phone Samsung, without connecting a computer. But there are some nuances: not all routers support configuration via a mobile app, and the interfaces Samsung Galaxy And One UI vary depending on the model.

In this article - step-by-step instructions for popular routers (TP-Link, ASUS, Keenetic etc.), analysis of encryption types (WPA3 vs WPA2), as well as solutions for problems when the phone "doesn't recognize" the router settings. We took into account the firmware specifics Samsung 2020–2026, so the instructions are relevant even for older flagships like Galaxy S10 or new ones Galaxy S23 Ultra.

⚠️ Attention: If your router is provided by your ISP (for example, Rostelecom or MTS), its settings may be blocked. In this case, you will need access to your operator's personal account—we'll cover this in a separate section.

1. Which Samsung phones support Wi-Fi setup?

Technically any smartphone Samsung on Android 8.0 and later can change the Wi-Fi password, but there are two key conditions:

  1. 5 GHz support. Older models (eg. Galaxy J3 2016) work only with networks 2.4 GHzIf your router broadcasts on two frequencies simultaneously, make sure you are connected to the correct one.
  2. Compatible with router app. Manufacturers like TP-Link or ASUS release official utilities (for example, Tether or ASUS Router), which may not support older versions Android.

Here is a list of models Samsung, which are guaranteed to cope with the task (tested on firmware One UI 4.0–6.1):

  • 📱 Galaxy S series: S20, S21, S22, S23 (including FE And Ultra)

⚠️ Attention: If the Wi-Fi indicator on the router flashes orange after changing the password, there was a saving error. Restart the router (button Reset for 10 seconds) and try again.

What should I do if the app doesn't find the router?

1. Make sure that your phone and router are on the same network (even if it is open).

2. Disable mobile internet (4G/5G) – it may conflict with Wi-Fi.

3. Check if the protocol is enabled in the router UPnP (needed for automatic detection).

4. Try connecting via a browser (method 2).

5. If the router is from a provider, its settings may be locked – see section 6.

4. Method 2: via a browser on your phone (universal method)

If the router app is not working or is missing, use the mobile browser (Samsung Internet, Chrome or Firefox). This method is suitable for any routers, including older models.

🔧 Step-by-step instructions

  1. Connect your phone to the router's Wi-Fi network.
  2. Open your browser and enter the router's IP address (e.g. 192.168.1.1). Click Go to.
  3. Enter your login and password (standard ones are admin/admin, if you haven't changed it). If it doesn't fit, look at the sticker on the bottom of the router.
  4. The router interface will open. Look for sections like:
    • Wireless / Wi-Fi / Wireless network
    • Security / Protection / Security
  • Select encryption type:
    • 🔒 WPA3-Personal — the most secure (supported by devices since 2019).

    3. Update your router's firmware through its control panel.
    4. Contact your router manufacturer or ISP support.

    FAQ: Answers to frequently asked questions

    Is it possible to set a Wi-Fi password without access to the router?

    No. To change network security settings, you need physical or remote access to the router's control panel. If you're not the network administrator (for example, if you're connected to Wi-Fi at a cafe), you won't be able to set a password.

    Which encryption type should I choose: WPA2 or WPA3?

    WPA3 It's safer, but not all devices support it (especially older smartphones, printers, and smart TVs). If your network includes devices older than 2019, choose WPA2-PSKFor maximum compatibility, you can enable the mode WPA2/WPA3 Transition (if it is in the router).

    What should I do if I forgot my router login and password?

    Reset your router to factory settings: press the button Reset on the back panel and hold for 10-15 seconds. After this, the login and password will become default (usually admin/admin or indicated on the sticker). Attention: This will disable all user settings!

    Is it possible to set a password on Wi-Fi via a USB cable?

    No, the USB cable is only used to connect the router to a computer for firmware or configuration in mode Media BridgeYou can change Wi-Fi settings only through the web interface, app, or Telnet/SSH (for advanced users).

    How to hide your Wi-Fi network name (SSID)?

    Find the option in your router settings Hide SSID or Hide SSID and turn it on. However, this doesn't improve security—advanced users can still find your network. It's better to use a strong password and WPA3.
