A tablet refusing to connect to a wireless network is one of the most common issues with mobile devices. Users may encounter an endless loop of attempting to obtain an IP address, constant disconnections, or a complete lack of visible networks in the list of available networks. A software glitch in the operating system is often the cause. Android or iPadOS, which can be easily eliminated by simply rebooting the communication module.
However, if simply turning Wi-Fi off and on doesn't help, the problem may lie deeper. This could be an IP address conflict, incorrect DNS settings, outdated router firmware, or even physical damage to the antenna inside the tablet itself after a fall. In this article, we'll walk you through a series of steps, from simple steps to complex settings, to help restore a stable connection.
Initial diagnostics and reboot of devices
The first and most effective step in 80% of cases is a complete system reboot. Many users forget that a router is also a computer with its own operating system, which accumulates cache errors. It's necessary to turn off the tablet and unplug the router for 15-20 seconds. This will allow the capacitors to fully discharge and reset the temporary memory buffers.
After turning on the router, wait until all the necessary indicators light up before turning on the tablet. Often, the device automatically finds the network and connects without any further action. If the problem persists, check to see if Airplane Mode is enabled. Sometimes the system gets stuck in this state, requiring you to force the slider to switch it.
It's also worth making sure the tablet's date and time are up-to-date. Inconsistencies in the time can lead to security certificate errors, causing the router to reject the device's connection, considering it suspicious.
⚠️ Note: If after rebooting your tablet, it sees other Wi-Fi networks but not your home network, the problem is most likely related to your router settings or frequency range, not the tablet itself.
Check Wi-Fi on other devices. If the internet isn't working on either your phone or laptop, the problem lies with your ISP or router, and it's too early to bother messing with your tablet's settings.
Managing network profiles and forgetting a network
Sometimes old or modified connection settings for a specific access point are stored in the tablet's memory. For example, you changed the password on your router, but the tablet is trying to log in with the old settings. In this case, you need to delete the network profile. Go to Wi-Fi settings, select your network, and tap "Forget network" or "Delete."
After deleting, re-enter your password. Pay attention to your keyboard layout and letter case—passwords are case-sensitive. A common mistake is confusing the number 0 with the letter O, or 1 with I. Enter your password carefully, using the "Show Password" feature for a visual check.
If your tablet connects but displays "Saved" or "Connected without internet access," try changing the security type in your router settings. Modern tablets may not work well with older encryption protocols. WEP or WPA/TKIPThe optimal choice is WPA2-PSK (AES) or WPA3.
It's also worth checking that the list of saved networks isn't full. Some older tablet models have a limit on the number of access points they can remember. If there are too many, the device may refuse to add new ones or work correctly with existing ones.
Setting up a static IP address
One technical reason why a tablet won't connect to Wi-Fi is an IP address conflict on the local network. This occurs when the router's DHCP server mistakenly assigns the same address to two different devices. As a result, one of them (often the tablet) can't connect online. The solution is to manually assign a static IP address.
To do this, select your network in the Wi-Fi settings, go to advanced settings, and find "IP Settings." Change the value from "DHCP" to "Static." You'll need to enter a few parameters. The IP address must be in the same subnet as the router (usually 192.168.0.X or 192.168.1.X), but not the same as the router itself.
You can specify the default gateway and DNS (the router's address) or use Google's public DNS (8.8.8.8), which often resolves website access issues. Below is a table with an example of the correct settings for a standard home network.
| Parameter | Meaning (Example 1) | Meaning (Example 2) | Description |
|---|---|---|---|
| IP address | 192.168.1.125 | 192.168.0.55 | The tablet's unique address on the network |
| Gateway (Router) | 192.168.1.1 | 192.168.0.1 | Access point address |
| Network mask | 255.255.255.0 | 255.255.255.0 | Determines the size of the local network |
| DNS 1 | 8.8.8.8 | 1.1.1.1 | Google/Cloudflare Domain Name Server |
After entering the information, save the settings and try connecting. If the tablet starts working, the issue was with the router's address allocation. You can leave the static address or try rebooting the router to reset its address lease table.

Problems with the 2.4 GHz and 5 GHz frequency ranges
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Older or budget tablet models may simply not see 5 GHz networks because their Wi-Fi module doesn't support this standard. 802.11ac or axIf your router only broadcasts 5 GHz or combines networks under one name (Smart Connect), your tablet may constantly lose connection.
It is recommended to separate networks in the router settings by giving them different names, for example, HomeWiFi And HomeWiFi_5GConnect your tablet to a 2.4 GHz network, which has better penetration through walls and is supported by almost all devices. The 5 GHz band is designed for high-speed data transfer over short distances.
The 2.4 GHz band can also be heavily interfered with by noise from neighboring routers and household appliances. In your router settings, try changing the broadcast channel from "Auto" to a fixed channel (1, 6, or 11), choosing the least congested one. This often stabilizes the connection.
⚠️ Note: Router and mobile operating system interfaces are constantly being updated. Menu item names may differ depending on the version. Android, iPadOS or your router model. If you can't find the setting, check the manufacturer's official documentation.
Reset network and system settings
If software errors have accumulated in system files, you may need to reset your network settings. This will delete all saved Wi-Fi passwords, Bluetooth, and cellular network settings, but will not affect your personal files, photos, or apps. This is a safe procedure that often resolves complex connection issues.
On Android the path usually looks like this: Settings → System → Reset settings → Reset Wi-Fi, mobile data, and Bluetooth settingsOn Apple devices: Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsAfter rebooting, the tablet will be as good as new in terms of network connections.
As a last resort, if all else fails, you can perform a full factory reset. Be sure to back up your data before doing this. This is a drastic measure, but it eliminates any software conflicts caused by installed apps or system errors.
What happens when you reset your network?
Resetting network settings deletes all saved Wi-Fi passwords, Bluetooth pairings (watches, headphones), and VPN settings. Your contacts, photos, apps, and files remain intact. This is a safe way to refresh your device's network stack.
Hardware faults and the Wi-Fi module
Once software solutions have been exhausted, the only remaining problem is the hardware. If the tablet was dropped, impacted, or exposed to water, the antenna connector inside the case may have come loose or the Wi-Fi module itself may have burned out. Symptoms include a gray Wi-Fi icon that won't turn on, or a complete failure to scan for networks even after a reset.
Sometimes the Wi-Fi module overheats. If the tablet has been running under heavy load (gaming, navigation) for a long time and has become very hot, the wireless module may temporarily shut down for protection. Let the device cool down while turned off and then test again.
It's also worth checking to see if the tablet has modified software or root access, which could interfere with the drivers. In some cases, reflashing the device via a computer can help, but this requires expertise.
In conclusion, most connection issues are resolved by rebooting the router and "forgetting" the network. However, if the problem stems from frequency incompatibilities or IP conflicts, manual configuration will be required. Regularly updating your router's firmware and tablet's operating system helps prevent similar situations in the future.
Frequently Asked Questions (FAQ)
Why does my tablet say "Obtaining IP address" and then drop the connection?
This is a classic sign of an IP address conflict or a faulty DHCP server on the router. Try setting a static IP address in the Wi-Fi settings on your tablet or rebooting the router. The issue could also be with your antivirus software or the hosts file if your tablet is rooted.
My tablet sees the 5 GHz network but won't connect. What's wrong?
Your tablet likely doesn't support the 802.11ac/ax standard or the 5 GHz band, even if it appears in the list (some routers show the network but block connections from incompatible devices). Try connecting to a 2.4 GHz network. Also, check if your router has MAC address filtering enabled.
How do I know if my tablet supports 5GHz?
Check the model's specifications on the manufacturer's official website. Look for standard support. 802.11a, 802.11n (5 GHz), 802.11ac or Wi-Fi 5/6. If only specified 802.11b/g/n Without specifying 5 GHz, most likely only 2.4 GHz is supported.
Can a case interfere with Wi-Fi on a tablet?
Yes, if your case has a metal back or metal inserts, they may block the antenna signal, which is usually located at the top of the case. Remove the case and check the signal strength and connection stability.
