Connecting a smartphone to a wireless network is a basic necessity for a modern user. This saves mobile traffic, ensures higher content loading speeds and stable operation of online services. The setup process on devices with an operating system Android is standardized, but may have slight differences depending on the OS version and the manufacturer's shell.
In most cases, the system independently detects available access points within range. The user only has to select the desired network and enter the secret key. However, there are situations that require manual intervention: hidden SSIDs, the need to configure a static IP address, or problems with automatic connection. Let's analyze in detail all aspects of interaction with wireless networks.
Basic connection to an open or known network
The most common scenario is connecting to a home router or a public point in a cafe. First you need to activate the wireless module. This is usually done through the quick access panel, which can be accessed by swiping down from the top edge of the screen. Find the fan-shaped icon and make sure it is highlighted in the active color.
If the icon is not active, go to the main settings menu. Find the section Connections or Network and Internet. Inside this menu there is a switch Wi-Fi. After its activation, the system will begin scanning the airwaves. A list of available networks will appear automatically. Select the desired name (SSID) from the list.
When you select a secure network, a password entry field will appear. Enter the security key indicated on the router sticker or received from the network administrator. Pay attention to the case of letters and special characters, as an error in even one character will result in denial of access. After entering, click the button Connect.
A successful connection is usually accompanied by the appearance of a signal icon in the status bar and a sound notification. The status under the network name will change to Connected. If the system displays an authentication error, check the correctness of the entered data or reboot the router.
If you often visit the same place, turn on the “Auto-connect” function. This will allow the smartphone to connect to the network automatically without asking for confirmation every time.
Setting up hidden wireless networks
Some network administrators intentionally hide the access point name (SSID) for security purposes. In this case, the network will not appear in the general list of available connections. To connect to such a resource, you need to manually add a profile.
Go to the Wi-Fi management menu and scroll down the list to the end. Usually there is an option Add network or Other network. In the window that opens, you will need to manually enter the network name (SSID). Be extremely careful: the name must match character by character, including spaces.
In the security field, select the encryption type. Most often used WPA/WPA2-Personal. If you don't know the encryption type, try the standard option; in case of an error, the system will report incompatible parameters. Enter your password and confirm.
⚠️ Attention: Connecting to hidden networks requires your phone to constantly send out requests to search for a specific name. This may slightly increase battery consumption compared to connecting to visible networks.
After saving the settings, the device will try to establish a connection. If the parameters are entered correctly, the phone will connect to the hidden access point. In the future, it will remember this network and connect to it automatically when it enters the coverage area.
Advanced settings: static IP and proxy
The standard operating mode involves automatically obtaining network settings via the protocol DHCP. The router itself gives the phone an IP address, gateway and DNS servers. However, in corporate networks or if there are specific restrictions, manual configuration may be required.
To change the settings, click on the name of an already saved network in the list and select Change or Network management. Expand additional settings by clicking on the arrow or gear. Find the item IP settings and switch the mode from DHCP to Static.
Fields for manual data entry will open. You need to specify:
- 📍 IP address: the unique address of the device on the local network (for example, 192.168.1.55).
- 🚪 Gateway: the address of your router (usually 192.168.1.1 or 192.168.0.1).
- 🔍 DNS: domain name server addresses (you can use public ones from Google: 8.8.8.8).
Incorrect gateway or subnet mask will result in no access to the Internet, even if the connection to the router is established. If you do not have exact data from the network administrator, it is better to leave the DHCP mode.
Why do you need a static IP?
A static address is needed to configure port forwarding, access smartphone files from a computer via a local network, or run specific server software on the phone.
Manage saved profiles and priority
Over time, many saved networks accumulate in the smartphone’s memory. The device may try to connect to a neighbor’s weak network instead of your powerful home point if the signal of the first one is slightly stronger at the time of search. List management helps optimize this process.
The function Saved networksis often available in the Wi-Fi menu. Here you can see a complete list of all access points ever used. You can delete old or unnecessary profiles by clicking on the trash icon or selecting Forget network. This will clear the memory and speed up the search for current connections.
On some smartphone models, especially with clean Android or shells from Samsung, there is a smart switching function. It analyzes signal quality and Internet speed. If the current network is not working well, the phone may offer to switch to the mobile data or another known Wi-Fi network.
| Parameter | Description | Recommendation |
|---|---|---|
| Auto-connection | Automatic login to the network | Enabled for home/office |
| Notifications | Notification about available networks | Disabled (to save) |
| Wi-Fi Assist | Switching to mobile data | Enabled (for stability) |
| MAC address | Device ID | Random (for privacy) |
Regularly clearing the list of saved networks improves search speed and prevents attempts to connect to unsafe or weak access points.
Diagnostics of problems and common errors
Even with correct configuration, failures may occur. The most common error is “Obtaining an IP address...”, which hangs for an indefinite amount of time. This often indicates an address conflict on the network or a problem with the router's DHCP server. Try rebooting both devices: the smartphone and the router.
Another common problem is constant connection disconnections. This may be caused by outdated Wi-Fi module drivers, interference from other electronic devices, or overheating of the smartphone. Check to see if the power saving mode is set, which turns off the wireless module when the screen is off.
If the phone sees the network but does not connect to it, check the date and time settings. A time zone mismatch may interfere with security protocols and certificates. Also make sure that MAC address filtering is not enabled on your router, which blocks new devices.
⚠️ Attention: If you see a “Connection is not secure” or “Certificate is not trusted” warning, do not enter personal data (passwords, card numbers) on this network. This may be a fake access point.
In difficult cases, resetting the network settings helps. This operation will delete all saved Wi-Fi networks, Bluetooth pairings and mobile settings, returning them to factory defaults. The path to the function usually looks like this: Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.

Security issues when using public networks
Connecting to open networks at airports, hotels and cafes carries certain risks. Attackers can intercept traffic or create fake access points with names similar to legitimate ones. Always check the exact name of the network with the establishment's staff.
When working on public networks, it is strongly recommended to use VPN services. They encrypt all outgoing traffic, making it unreadable to potential eavesdroppers. Even if the network requires entering a password on the authorization page (Captive Portal), this does not guarantee the security of data transmission within the network.
Modern versions Android use the MAC address randomization function. By default, the phone generates a random address for each new network, making it difficult to track a user's movements across access points. Do not disable this feature without a good reason, such as if a particular network requires you to register with a real MAC address.
What is Captive Portal?
It is a web page that opens automatically when you connect to a public network. On it you need to click the “Connect” button, accept the terms of the agreement or enter the code from SMS to gain access to the Internet.
Why doesn’t the phone see the Wi-Fi network, although other devices do?
Perhaps your smartphone does not support the encryption standard or the frequency at which the router operates. Check if only the 5 GHz band is enabled on the router if the phone is old and only supports 2.4 GHz. Also try to forget the network on other devices and recreate it.
How to find the password for a saved Wi-Fi network on Android?
On versions of Android 10 and higher, you can see the password in the network settings. Click on the gear next to the network name, select the "Share" option or the QR code icon. The password will be indicated under the QR code or it can be read by another phone.
Does the smartphone case affect the reception of the Wi-Fi signal?
Yes, it can. Cases with metal inserts, magnets, or too thick a layer of material can shield the antenna. If the signal is weak only in the case, try removing it and checking the quality of the connection.
What to do if the Wi-Fi speed is very low?
Try switching from the 2.4 GHz band to 5 GHz if the router supports dual-band mode. Make sure you are not downloading large files on other devices on the network. Also check if the smartphone is too far from the router.
Is it possible to add a Wi-Fi network without entering a password?
Only if the network is open (without a lock) or if you use the WPS function (button on the router), which allows you to connect with the press of a button, although WPS support on new phones is often disabled for reasons security.
