Samsung Galaxy Tab 3 it is often called Connections or immediately Wi-FiOnce inside, you'll see a slider switch at the top of the screen. If it's in the "Off" position or grayed out, tap it to activate it. The system will begin scanning the airwaves.
After a few seconds, a list of available access points will appear on the screen. Network names (SSIDs) will be listed in descending signal strength order, with those closest to the tablet at the top. If the desired network isn't listed, make sure your router isn't hiding its SSID and is within range.
- 📡 Make sure the Wi-Fi slider is green, which indicates that the module is active.
- 🔍 Click the refresh button (usually three dots or arrows) if the list of networks does not appear automatically.
- 📶 Look for a lock icon next to the network name—it means a password is required to connect.
- ⚙️ The signal strength may be displayed next to the network name as a scale with divisions.
⚠️ Attention: Avoid connecting to open networks with suspicious names in public places, as data transmission through them can be intercepted by attackers.
Connecting to a secure network and entering a password
Once you find your home or office network in the list, tap its name. If the network is open, the connection will be instant. However, in most cases, the security system will require authorization. A pop-up window will appear with data entry fields and control buttons.

Advanced IP and DNS settings
In standard mode Samsung Galaxy Tab 3 Automatically obtains an IP address and DNS servers from the router via DHCP. This is the simplest and most reliable method, working 95% of the time. However, in some situations, such as address conflicts or access to specific resources, manual configuration is required.
To switch to manual configuration mode, tap and hold your network name in the list of networks (or tap the "Advanced" button / three dots to the right of the name). In the context menu that opens, select Change network or AdditionallyFind the line IP settings and switch it from DHCP to Static.
Fields for manual parameter entry will open. Here, you must specify the device's IP address, gateway (router address), and DNS. Speed or website access issues are often resolved by specifying public DNS servers, such as Google (8.8.8.8) or Yandex (77.88.8.8). This can speed up system response times when loading pages.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP address | The tablet's unique address on the network | 192.168.1.150 |
| Gateway | Your router's address | 192.168.1.1 |
| Network prefix length | Subnet mask | 24 |
| DNS 1 | Primary name server | 8.8.8.8 |
After making changes, be sure to click SaveThe tablet will reconnect to the network with the new settings. If you make a mistake in the numbers, you will lose internet access, so write down the original values or take a screenshot before making any changes.
Manage known networks and connection priority
Device Samsung Galaxy Tab 3 Remembers all the networks you've ever connected to. This is convenient, as when you enter the range of a familiar access point, the tablet will connect to it automatically. However, the list can become too large, or the priorities can become off, causing the device to connect to a weak network instead of a strong one.
In the Wi-Fi menu, often under the menu button (three dots in the corner) or by long pressing on the network name, the function is available Forget the network or Delete networkUsing this option completely erases the saved password and settings for the selected access point. This is useful if you've changed the password on your router or sold the equipment.
Connection priority is usually based on the "last-connected" principle or signal strength. If you have two routers at home with the same name (SSID), your tablet may try to connect to the one that's farther away but has a weaker signal. In such cases, deleting the unnecessary network from memory helps stabilize the connection.
- 🗑️ Regularly delete old cafe and hotel networks to avoid cluttering your memory and speed up your home network search.
- 🏠 For your home network, you can use the "Auto-connect" feature to let your tablet establish a connection automatically.
- 📉 If the signal drops, try "forgetting" the network and reconnecting to reset the connection cache.
⚠️ Attention: After performing the "Forget network" action, you will have to re-enter the password the next time you connect to this access point.
Diagnosing connection and driver issues
Despite the ease of setup, users Galaxy Tab 3 You may encounter a situation where your tablet sees the network but doesn't connect, or displays the message "Obtaining IP address..." and then disconnects. This is often due to incompatible encryption protocols. Older devices may not work well with the new standard. WPA3 or mixed mode WPA2/WPA3.
In this case, it is recommended to go to the router settings (via a computer or phone) and try changing the wireless network security type to WPA2-PSK (AES)It's also worth checking the frequency range: this tablet model may not support the 5 GHz frequency, operating only in the 2.4 GHz band. Make sure compatibility mode is enabled on your router.
Another cause of crashes could be outdated system files or a full network service cache. In this case, resetting network settings can help. To do this, go to Settings → General → Reset → Reset network settingsPlease note that this action will delete all saved Wi-Fi passwords and Bluetooth pairings, but will not affect your personal files and photos.
What should I do if my tablet says "Authentication Error"?
Most often, this means the password is incorrect. However, if you're sure of the password, the issue may be with the encryption type on your router. Try temporarily disabling the password on your router. If the tablet connects to the open network, the module is working properly, and the issue lies with the router's security settings (try changing WPA3 to WPA2).
Optimizing power consumption and signal stability
The Wi-Fi module is one of the main energy consumers in the tablet. Samsung Galaxy Tab 3, which no longer has a young battery, proper settings can extend battery life. In the Wi-Fi menu, under additional settings (three dots), there's often a hidden option Wi-Fi in sleep mode.
