Connecting to Wi-Fi on a smartphone Android 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 get the hang of the process in 5-10 minutes. We'll cover not only basic setup but also solutions for hidden networks, dual-band routers (2.4 GHz And 5 GHz), as well as common mistakes that are not described in the official guides.
Important: The Wi-Fi connection algorithm is Android has remained virtually unchanged since version Android 8.0 Oreo, but manufacturers like Samsung, Xiaomi or Realme The interface is often modified. If your smartphone runs on MIUI, One UI or ColorOS, pay attention to the screenshots - we'll point out the key differences. For owners of devices with Android 14 and newer, we added a separate section with changes to security settings.
Before you begin, check three things:
- 📶 The router is turned on and distributes Wi-Fi (indicator
WLAN/Wi-Fi(lights up or flashes). - 🔒 Do you know the password? from the network (if the network is protected). On some routers, this is indicated on a sticker on the bottom.
- 📱 Airplane mode is disabled — You can check by pulling down the notification shade.
1. Basic Wi-Fi Connection on Android: Step-by-Step
If you've never connected your smartphone to Wi-Fi before or are doing so for the first time after a factory reset, follow these instructions. This guide is for 90% of devices on Android 6.0–14.
Open smartphone settings (gear icon in the application menu or on the desktop). Next:
- Go to the section
Network and Internet(on Samsung —Connections, on Xiaomi —Wi-Fidirectly in the main settings menu). - Click on
Wi-Fiand move the slider to the right to enable the module. - Wait for your smartphone to search for available networks. Select your network (the name is indicated on the router or in its settings).
- Enter password (case sensitive!) and press
Connect.
If the password is entered correctly, an icon will appear next to the network name. "Connected" (check mark or waves). To check your internet access, open your browser and try loading any website, for example google.com.
Check if Wi-Fi is enabled on the router (WPS/Wi-Fi button)
Reboot your router (unplug it from the power outlet for 30 seconds)
Make sure your smartphone is within range of the network (no further than 10-15 meters from the router)
Try connecting to another network (neighbors, public) to rule out the problem with your phone-->
2. Connect to a hidden Wi-Fi network
Some networks (for example, in offices or hotels) hidden — they don't appear in the general list, but you can connect to them manually. To do this:
- In the Wi-Fi settings, tap
Add a network(orOther networks→Add manuallyon Xiaomi). - In the field
Network name (SSID)enter exact name hidden network (check with your administrator or look in your router settings). - Select security type:
- 🔐
WPA2-PSK— the most common (recommended). - 🔓
No- if the network is open (not secure!). - 🛡️
WPA3-PSK- for modern routers (for example, ASUS RT-AX88U).
- 🔐
If your smartphone doesn't save the hidden network after a reboot, check your router settings: the "Hide SSID" option should be enabled, but it shouldn't conflict with the "Client Isolation" function (if it's active).
Why are hidden networks less secure?
A counterargument to the common belief: hiding the SSID doesn't protect against hackers, as the network name is still transmitted in plaintext when connecting. However, it does reduce the number of random connection attempts from unauthorized devices, which is useful in public areas.
3. Choosing between 2.4 GHz and 5 GHz: Which network should you choose?
Modern routers broadcast in two ranges:
- 📡
2.4 GHz— greater range, but lower speed and higher congestion (neighboring networks may interfere). - ⚡
5 GHz- higher speed and stability, but weaker penetration through walls.
Typically, your smartphone will automatically connect to the most optimal network, but you can select the range manually:
- In the list of Wi-Fi networks, find your network ending with
_5Gor5GHz(For example,MyWiFi_5G). - Connect to it as you would to a regular network.
| Parameter | 2.4 GHz |
5 GHz |
|---|---|---|
| Maximum speed | Up to 300 Mbps | Up to 1–2 Gbps |
| Range | Up to 50–70 m (indoors) | Up to 20–30 m (depending heavily on obstacles) |
| Interference from other networks | High (11 channels, of which only 3 do not overlap) | Low (no more overlapping channels) |
| Support for older devices | Yes (all smartphones) | No (devices before 2015 may not see it) |
4. Troubleshooting Wi-Fi connection errors
If a smartphone won't connect to Wi-Fi or shows an error, try these methods (from simple to complex):
Error: "Authentication" or "Saved, but no internet connection"
- 🔄 Reboot your router (pull out the power cord for 30 seconds).
- 📱 Forget the network on smartphone:
- Tap and hold the network name in the Wi-Fi list →
Delete(orForget). - Please reconnect by entering your password.
- Tap and hold the network name in the Wi-Fi list →
- If used
WEP- change toWPA2-PSK(WEPis obsolete and not supported after Android 10). - If
WPA3- try switching temporarily toWPA2(some older smartphones are not compatible).
Error: "IP address not received" or "Connecting..." hangs indefinitely
The problem is often related to DHCP server router. Solutions:
- 🔧 Assign static IP manually:
- In the Wi-Fi settings on your smartphone, tap on your network →
Change network→Additionally. - In the field
IP settingsselectStatic. - Enter an IP address from your router's range (e.g.
192.168.1.100, if the router192.168.1.1). - Gateway and DNS - specify the router IP (for example,
192.168.1.1).
- In the Wi-Fi settings on your smartphone, tap on your network →
5. Setting up Wi-Fi on Android 14 and later: what's changed?
IN Android 14 Google has made several changes to Wi-Fi that few people know about:
- 🔐 Improved password protection: Now when connecting to open networks, the system automatically offers to use
VPN(if installed). - 📊 Network quality monitoring: a connection stability graph has appeared in the Wi-Fi settings (available on Pixel and some Samsung).
- 🔄 Quick reconnection: If the network is lost, the smartphone tries to reconnect without asking for a password.
- Go to
Settings → Network & Internet → Wi-Fi → Wi-Fi Preferences. - Activate options:
- 🔄
Automatic reconnection - 📊
Network quality assessment - 🔒
Security in open networks(VPN app required)
- 🔄
- On your smartphone, open Wi-Fi settings and tap
Additionally→WPS(orConnection via WPS). - Press the physical button on the router
WPS(usually marked with a 🔄 icon). - Wait for connection (1-2 minutes).
- In the router's web interface (
192.168.1.1or192.168.0.1) find the sectionWi-Fi→QR code. - Scan the code with your smartphone camera and you will be prompted to connect.
To enable these features:
Attention! On some firmware (for example, MIUI 15) These options may be in a different menu or missing. Check for system updates.
6. How to connect to Wi-Fi without a password (WPS, QR code)
If you don't know the Wi-Fi password but have physical access to the router, you can use alternative connection methods:
Method 1: WPS (Wi-Fi Protected Setup)
Function WPS Allows you to connect to the network without entering a password by pressing a button on the router. Instructions:
⚠️ Attention: WPS is considered insecure - after connecting, disable this feature in your router settings!
Method 2: QR code (on supported routers)
Some routers (eg. TP-Link Archer AX6000 or Keenetic) generate a QR code for connection:
How to find out the IP address of a router?
If you don't know the router's IP, open Settings → Network & Internet → Wi-Fi, click on your network and look at the field Gateway or Router. Usually it is 192.168.1.1 or 192.168.0.1.
7. Checking Wi-Fi speed and stability
If Wi-Fi is connected, but the internet is slow or breaks off, run diagnostics:
- Check the speed using applications:
- 📊 Speedtest by Ookla (shows ping, download, upload).
- 📶 WiFi Analyzer (analyzes channel load).
- Optimize your Wi-Fi channel:
- Open your router settings (
192.168.1.1) →Wi-Fi→Channel. - For
2.4 GHzselect channels1,6or11(they do not intersect). - For
5 GHzuse channels36–48or149–165(less busy).
- Open your router settings (
- Move microwaves, cordless phones, and other devices away from the router.
2.4 GHz. - If you use
5 GHz, make sure there are no thick walls between the router and the smartphone.
⚠️ Attention: If your Wi-Fi speed is slower than your cable speed, check your settings. QoS on the router - priority for mobile devices may be limited.
8. Frequently asked questions about connecting Wi-Fi on Android
❓ Why can't my smartphone see my Wi-Fi network, but other devices can?
Possible reasons:
- 📡 The router is broadcasting in the range
5 GHz, and your smartphone does not support it (relevant for devices before 2015). - 🔧 The filter is enabled in the router settings MAC address (add your smartphone's address to the whitelist).
- 📵 The network is hidden (SSID is not broadcast) - connect manually (see Section 2).
- 🔋 The Wi-Fi module is disabled on the smartphone (check in
Settings → Connections → Mobile networks → Tethering and portable hotspot, if there is an optionTurn off Wi-Fi).
❓ How do I reset network settings on Android?
If your Wi-Fi is unstable, resetting your network settings may help:
- Open
Settings → System → Reset(on Samsung:General Management → Reset). - Select
Reset network settings(orReset Wi-Fi, mobile network, and Bluetooth). - Confirm the action. After the reboot, all saved networks and passwords will be deleted!
Attention: This reset will also delete settings Bluetooth, VPN And mobile Internet.
❓ Is it possible to connect to Wi-Fi without a password if I know the network name?
No, if the network is secure (WPA2/WPA3). The only legal ways are:
- 🔑 Ask the network owner for the password.
- 📱 Use WPS (if the function is enabled on the router).
- 🖼️ Scan QR code (if the router generates it).
Hacking into other people's networks is illegal and punishable under Article 272 of the Russian Criminal Code ("Unauthorized access to computer information").
❓ Why does Wi-Fi only work near the router?
Reasons for weak signal:
- 📡 The router is running on
5 GHz- this range does not pass through walls well. - 🏠Too many obstacles (concrete walls, metal structures).
- 🔋 Router transmission power is limited (check settings)
Tx Powerin the web interface). - 📱 The smartphone antennas are damaged (check if Wi-Fi works on other devices in the same area).
Solutions:
- 🔄 Switch to
2.4 GHz(lower speed, but larger radius). - 📡 Use repeater (signal repeater) or Mesh system.
- 📍 Move the router to the center of the apartment/house.
❓ How do I connect to public Wi-Fi (in a cafe, at the airport)?
Public networks often require additional authentication:
- Connect to the network (the password is usually on the counter or receipt).
- Open your browser - a login window should appear (if not, go to
1.1.1.1orneverssl.com). - Enter your details (phone number, email or code from the receipt).
