Connecting to a wireless network is the first action that the user takes after purchasing a new device or resetting the settings. Internet connection opens access to the application store, cloud storage and streaming content. The process seems elementary, but modern versions of the operating system Android offer many options that many are not aware of.
In this article we will analyze in detail not only the standard connection algorithm, but also the nuances of working with hidden access points, setting up a static IP address and diagnosing common errors. You will learn how to make your smartphone work in corporate networks with certificates and why sometimes it is necessary to manually enter DNS servers.
Basic algorithm for connecting to an open network
The most common scenario is connecting to a home or office network, the name of which is (SSID) is broadcast on air. To do this, just unlock the device screen and lower the notification shade. Click on the icon Wi-Fito activate the module if it is disabled.
Next go to the full-screen settings menu. This is usually done by long pressing on the same icon in the curtain or through the item Settings → Connections → Wi-Fi. The system will automatically scan for available access points within range. The list is updated in real time, displaying the signal level in the form of bars or colored indicators.
Select the desired network from the list. If it is password protected (as indicated by the padlock icon next to the name), the system will ask for authentication information. Enter the security key, making sure the case is correct, and press the Connectbutton. Successful authorization will be confirmed by the appearance of a check mark or the words “Connected” under the name of the network.
☑️ Check before connecting
Working with hidden networks and manual configuration
Not all wireless networks broadcast their name. Administrators often hide SSID (Service Set Identifier) for security purposes or to reduce interference on the air. In this case, your network will not appear in the general list, and automatic connection will become impossible without manual configuration.
To add such a network, you need to scroll down the list of available points to the very end. There you will find the item Add network or Other network. By clicking on it, you will open a form for manually entering parameters. It is critical to specify the network name accurately, respecting the case of letters and special characters.
⚠️ Attention: When connecting to a hidden network, the device will constantly send broadcast requests with the name of this network, even when you are out of coverage area. This may slightly increase battery consumption.
After entering the network name, select the protection type. In 99% of cases for home routers this is WPA/WPA2-Personal. If you select the wrong encryption type, the connection will fail with an authentication error, even if the password is correct. Complete the process by entering your password and saving the configuration.
Why is the SSID hidden?
Hiding the network name is not a reliable security method. Attackers with simple equipment can easily detect hidden networks using service data packets. This is only protection from random neighbors, but not from hackers.
Advanced IP and DNS settings
By default, Android uses a protocol DHCPthat automatically receives the IP address, gateway and DNS from the router. However, in some situations manual configuration is required. For example, if you want to block advertising at the network level or connect to a printer with a fixed address.
To change parameters, click on the gear next to the name of an already connected network or select Advanced in the add a new network menu. Find the line IP settings and switch it from DHCP to Static. Fields for entering numeric values will open.
You will need to enter the following data:
- 📍 IP address: unique address of the device on the local network (for example, 192.168.1.55).
- 🚪 Gateway: usually this is the address of your router (often 192.168.1.1 or 192.168.0.1).
- 🌐 DNS 1 and DNS 2: domain servers names You can use public DNS from Google (8.8.8.8) or Cloudflare (1.1.1.1).
| Parameter | Description | Example value |
|---|---|---|
| IP address | Unique device number on the network | 192.168.1.105 |
| Network prefix length | Subnet mask in CIDR format | 24 |
| Gateway | Router address | 192.168.1.1 |
| DNS 1 | Primary name server | 8.8.8.8 |
Be careful when entering a static IP. If you specify an address that is already occupied by another device on the network, a conflict will arise and the Internet will be lost for both gadgets. It is recommended to select addresses in the free range, for example, from 192.168.1.200 to 192.168.1.250.
Use a static IP if you configure port forwarding on the router for games or remote access to files on the phone.
Connecting to corporate networks (802.1x EAP)
Offices, universities and large organizations often use secure networks of the standard 802.1x. Connecting to them requires not just a password, but specifying the EAP (Extensible Authentication Protocol) method, user name and sometimes installing certificates.
When selecting such a network in the IP settings menu, be sure to leave DHCPbut expand additional parameters. In the field EAP method most often selected PEAP or TLS. Option TLS requires an installed security certificate in the phone's memory, which must first be downloaded from the system administrator.
For the method PEAP just enter the login and password for your domain account. Pay attention to the field CA Certificate. If your organization does not use internal certificate authorities, select the Do not check or Do not validateoption. Otherwise, the phone will reject the connection.
⚠️ Attention: The corporate network settings interface may vary greatly on different firmware (Samsung One UI, Xiaomi MIUI, Stock Android). If you do not see the required fields, try deleting the network and adding it again through the "Add network" menu.
Using WPS technology for fast connection
Function WPS (Wi-Fi Protected Setup) allows you to connect to the router without entering a long password. This is convenient if the access key consists of complex characters or you have forgotten it. On Android, this function is sometimes hidden in a submenu or accessible only through a button on the router itself.
There are two main methods of activation. The first is to look for a button on the router case. Press it, and then within two minutes select the item WPS buttonin the phone menu. The devices will find each other and exchange encryption keys automatically.
The second method is to enter a PIN code. The phone will generate an eight-digit code that must be entered into the router setup interface. However, this method is considered less secure, since the PIN code can be guessed by brute force. Modern versions of Android may limit this function for security reasons.
Path to the function (may vary):
Settings → Wi-Fi → Advanced (three dots) → Advanced → WPS button
It is worth noting that WPS support is on the side of mobile devices is gradually becoming a thing of the past. Many new smartphones simply do not have this item in the menu, offering instead a function QR code for instant connection.
Diagnosis of problems and saved networks
Sometimes the phone sees the network, but does not connect to it, giving the error "Receiving IP Addresses" or "Authentication". In such cases, it is useful to manage the list of saved networks. Go to the Wi-Fi settings, click on the three dots or gear and select Saved networks.
Find the problematic network in the list and click Delete or Forget. This will clear the error cache and old configuration settings. After that, try to connect again by entering the password from scratch. This often solves the problem of incompatibility of encryption protocols.
- 🔄 Reboot: simply turning off and on the Wi-Fi module or completely rebooting the smartphone helps in 50% of cases.
- 📡 Frequency range: make sure that your phone supports the router frequency. Old models do not see the network 5 GHz.
- 🔒 MAC filtering: MAC address filtering may be enabled on the router, and your device is blacklisted.
If the phone says “Saved, protected”, but there is no Internet, the problem is most likely on the side of the router or provider, and not in the phone settings.
⚠️ Attention: Functions and menu names may change depending on the version of Android and the manufacturer’s shell. If you do not find the described item, look for a similar one or refer to the documentation of your device.
Frequently asked questions (FAQ)
Why doesn’t my phone see my Wi-Fi network, although other devices do?
Probably, your router operates in the 5 GHz band, and your smartphone only supports 2.4 GHz. Also check if the SSID is hidden in the router settings. Try to get closer to the router to eliminate the problem of a weak signal.
How to connect to Wi-Fi without entering a password?
This is possible if the router has a WPS button and it is activated, or if the owner of the network has generated a QR code for you. Scanning such a code with your phone camera will automatically apply the network settings.
What to do if the network remains intact, but is constantly disconnected?
Try disabling the "Switch to mobile data" function in the Wi-Fi settings. Also check that the "Avoid bad connections" checkbox is unchecked. If the problem persists, reset the network settings on your phone.
Is it possible to add a Wi-Fi network if the phone screen is broken?
Yes, if USB debugging is enabled. You can use a computer and the ADB utility to enter connection commands, or connect a USB mouse via an OTG cable to control the interface.
Does adding a network affect the speed of mobile data?
No, these are two independent subsystems. However, if the phone constantly tries to connect to a weak stored Wi-Fi network, it may temporarily lose packet data. Use the Smart Wi-Fi function to automatically switch.
