The situation when the beloved Android or iPad A sudden internet outage can catch you off guard at the most inopportune moment. You see the connection icon, but the internet isn't working, or the device can't even see your home network. Often, the problem isn't a hardware failure, but a simple software glitch or a router settings conflict.
In this article we will look at the main reasons why The tablet won't connect to Wi-Fi., and we'll offer step-by-step solutions. We'll cover everything from simple steps like rebooting to complex DNS and static IP address manipulation. Understanding the nature of the error will save you time and frustration.
Before moving on to complex settings, it's best to rule out basic issues. Sometimes, simply turning the wireless module off and on or rebooting the router itself is enough. If this doesn't help, the problem lies with deeper operating system or hardware settings.
Basic diagnostics and module reboot
The first step is to perform a so-called "soft reset" of the network interfaces. This action clears temporary errors in the TCP/IP protocol stack that may have accumulated over time. On many devices, simply move the Wi-Fi slider to the "Off" position, wait 10-15 seconds, and then turn it back on.
If moving the slider doesn't help, a full reboot of the tablet itself is required. The shutdown process clears the RAM and all system services, including network driver, are restarted from scratch. This eliminates up to 70% of software glitches associated with communication module freezing.
⚠️ Important: If after rebooting your tablet, it sees other networks but not yours, the problem may be with your router. Check if other devices, such as a smartphone or laptop, are connected to it.
Don't forget to reboot your router. Routers are also small computers that can overheat or accumulate errors in the NAT table. Unplug the router for 30 seconds, then plug it back in and wait for it to fully boot up (usually 2-3 minutes). After that, try connecting your tablet again.
Problems with entering password and encryption type
One of the most common reasons for access denial is a simple error when entering the security key. Operating systems Android And iOS React differently to an incorrect password: some display "Authentication Error," while others endlessly attempt to connect. Always check your keyboard layout and capitalization.
Pay special attention to hidden characters. If you're copying a password from another source, make sure there's no space at the end of the line. Matching the encryption type is also important. Modern routers use the standard WPA2/WPA3, while older tablets may only support WPA.
- 🔑 Check if Caps Lock or another language layout is enabled when typing.
- 📡 Make sure your router doesn't use the outdated WEP protocol, which newer devices may block.
- 🔄 Try temporarily changing the password on your router to a simple one (numbers only) to avoid entering complex characters incorrectly.
In some cases, deleting a network from the list of saved networks can help. Find your network in the list of known networks, tap "Forget network" or "Delete," and then reconnect using the details manually. This forces the device to go through the entire handshake process with the access point again.
DHCP errors and IP address conflicts
A common reason why The tablet won't connect to Wi-Fi., is a failure in the DHCP (Dynamic Host Configuration Protocol) service. This service on the router is responsible for assigning unique IP addresses to each device on the network. If the address pool is exhausted or a conflict occurs, new devices will not be able to access the network.
An IP address conflict occurs when two devices on the same network are assigned the same static address. For example, you manually assigned the address 192.168.1.50 on your tablet, but the router has already assigned the same address to your laptop. Such a network results in chaos, and data packets are lost.
To resolve the issue, you can try resetting your tablet's network settings to factory defaults. This will delete all saved Wi-Fi networks, Bluetooth settings, and cellular networks, but will return the network stack to its original state. The path to this function is usually found in the menu. System → Reset settings → Reset Wi-Fi, mobile data, and Bluetooth settings.
☑️ DHCP Problem Diagnosis
If automatic address assignment doesn't work, you can manually assign an IP address. To do this, go to your Wi-Fi network settings, select "Advanced" or "Advanced Settings," find "IP Settings," and switch from DHCP to "Static."
IP address: 192.168.1.155Gateway: 192.168.1.1
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 8.8.4.4
It's important to specify an address in the same range as your router, but outside the active DHCP range, to avoid future conflicts. Routers typically assign addresses between 100 and 200, so feel free to use 50 or 250.
2.4 GHz and 5 GHz frequency bands
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Older or budget tablet models may not physically support this band. 5 GHzIf your router broadcasts only in this range (or has combined them under one name with 5 GHz as the priority), the device simply won't see the signal.
The 5 GHz band offers high speeds, but has a shorter range and is less effective at penetrating walls. If your tablet is far from the router, it may not connect to the 5 GHz network, even if it supports it. In this case, you should switch to the 2.4 GHz network.
| Characteristic | 2.4 GHz | 5 GHz |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 1000+ Mbps |
| Range | High (up to 50 m) | Medium (up to 20 m) |
| Permeability of walls | Good | Bad |
| Susceptibility to interference | High (microwaves, Bluetooth) | Low |
To check range support, you can use special applications such as WiFi AnalyzerThey will show which frequencies your tablet can see. If the 5 GHz network isn't listed, but 2.4 GHz is, it's a hardware compatibility issue.
Why might a router hide a 5GHz network?
Some router manufacturers combine both bands into a single network with the same name (SSID) by default. Smart devices automatically select the best frequency. However, older tablets may get lost in such hybrid networks. Solution: Separate the networks in the router settings by giving them different names, for example, "Home_WiFi_2.4" and "Home_WiFi_5."
Problems with DNS and ISP
Sometimes the tablet shows the "Connected" status, but web pages won't open in the browser. This is a classic sign of DNS (Domain Name System) issues. The provider's servers may not be responding, or their addresses may not have been transmitted correctly to the device. In this case, The tablet won't connect to Wi-Fi. in the full sense of the word, since there is no internet traffic.
To diagnose, try opening the site by IP address (for example, http://142.250.185.206 (This is Google). If a site opens by IP but not by name, the problem is definitely DNS. This can be resolved by manually registering public servers.
- 🌐 Google Public DNS:
8.8.8.8And8.8.4.4. - ☁️ Cloudflare DNS:
1.1.1.1And1.0.0.1. - 🛡️ Yandex DNS (secure):
77.88.8.8And77.88.8.1.
Enter these addresses in your Wi-Fi connection settings (under "Static IP" or "DNS," as described above). This often resolves issues when your ISP is blocking access or its nameservers are overloaded. It's also worth checking your account balance and any blocking issues from your ISP.
⚠️ Important: If you use a VPN or proxy service, try disabling them. An incorrectly configured tunnel can block all device traffic, creating the illusion that there is no network.
Hardware faults and drivers
If software solutions don't help, hardware issues cannot be ruled out. The Wi-Fi antenna inside the tablet may have become detached from the board after a fall. This is not noticeable visually, but a symptom will be an extremely weak signal or complete lack of network coverage even near the router.
The Wi-Fi module itself may also be damaged. If the module appears as "Unknown Device" or is missing entirely in Device Manager (on a PC when connected via USB modem) or in the tablet's system information, this is a sign of hardware failure. In such cases, repairs at a service center are required.
On devices Android Sometimes, system driver files become corrupted after an unsuccessful firmware update. In this case, a factory reset (hard reset) may help. Keep in mind that this will delete all your data, so make a backup first.
Advanced users with root access can reflash the Wi-Fi module, but this requires extensive knowledge and carries the risk of bricking the device. For the average user, a factory reset or contacting a specialist is best.
FAQ: Frequently Asked Questions
Why does my tablet connect to Wi-Fi, but the internet doesn't work?
The problem is most likely with your DNS servers or date and time settings. Check that the time on your device is set correctly (a time error can break websites' SSL certificates). Also, try setting Google's DNS (8.8.8.8).
What should I do if my tablet says "Obtaining IP address..." and freezes?
This is a DHCP issue. Try increasing the pool of allocated addresses on your router or disabling MAC address filtering. On your tablet, you can try manually setting a static IP address.
Can a case interfere with Wi-Fi reception?
Yes, if the case has a metal base or contains metal-plated elements. Metal shields the signal. Remove the case and check the connection.
Why can't my iPad see 5GHz Wi-Fi?
iPad models prior to the 3rd or 4th generation and older iPad minis do not support the 5 GHz band. They only have access to 2.4 GHz. Make sure your router broadcasts a network in this range.
How do I know if my Wi-Fi module is burned out?
If after a full reset (Factory Reset) the tablet still does not see any networks, but the networks of neighboring devices (phone, laptop) work normally, there is a high probability that the Wi-Fi module is faulty.
