Tablet Won't Connect to Wi-Fi: Causes and Fixes

Are you trying to access the internet on your tablet, but instead of pages loading, you see the message "No network access" or the connection icon spinning endlessly? This problem occurs on devices of all brands, from budget ones Lenovo Tab to the flagship iPad Pro And Samsung Galaxy Tab SIn 80% of cases, the problem can be resolved without calling a service center, but this requires accurately identifying the source of the problem.

In this article we will look at all possible reasons, where your tablet doesn't have Wi-Fi or connects to the network but can't open websites. You'll learn how to distinguish a hardware defect from a software glitch, which router settings are blocking internet access, and what to do if the problem only occurs on one device. For your convenience, we've compiled a diagnostic checklist and added interactive surveys so you can find a solution faster.

Let us warn you right away: if your tablet doesn't see the Wi-Fi network at all (even neighboring ones), and in the tray there is a cross on the wireless connection icon - most likely the problem is in hardware (antenna, Wi-Fi module). In other cases, the software methods described below will help.

1. Checking basic parameters: router and tablet

Start with the basics—users often miss the obvious. For example, the router may be disconnected from power, and Airplane mode is enabled on your tablet. Go through this list:

• 🔌 Router power supply: check that the indicators on the case are lit (especially Power And Wi-Fi). If only blinks Power — the device is frozen and requires a reboot.
• 📶 Airplane Mode: On your tablet, swipe down on the notification bar and make sure the airplane icon is inactive. iPad take a look at Control center.
• 🔒 MAC address blocking: some routers (for example, TP-Link or Keenetic) by default prohibit new devices from connecting. Check the list of allowed MAC addresses in the settings.
• 🔄 Rebooting devices: Turn off the tablet and the router for 30 seconds, then turn on the router first, and after a minute, the tablet.

If the Internet still doesn't work after these steps, proceed to the next section. Pay special attention to the section on MAC addresses: in 2026, many providers (for example, Rostelecom or MTS) began actively using this feature to protect against unauthorized access.

2. Connection errors: "Authentication", "Obtaining IP" and others

When the tablet sees the network, but does not connect to it, one of the errors usually appears on the screen:

• 🔐 "Authentication..." / "Authentication Error" - Incorrect password or encryption type.
• 🆔 "Getting IP address..." (endless) — DHCP failure on the router or IP conflict.
• ⚠️ "Saved, WPA/WPA2 protection" - incompatibility of security protocols.
• 🚫 "No internet access" — the tablet is connected to the router, but it is not distributing traffic.

Let's look at each error separately.

2.1. "Authentication" or "Authentication Error"

This error means that the tablet cannot pass password verificationReasons:

• 🔑 You entered an incorrect password (case sensitive!)
• 🔄 The encryption type on the router has changed (for example, from WPA2-PSK on WPA3), but the tablet does not support it.
• 🕒 The password was reset after updating the router firmware (relevant for ASUS And Zyxel).

Solution:

1. Please make sure you entered your password correctly. iPad You can see the entered characters by clicking on the eye in the password field.
2. Go to your router settings (192.168.0.1 or 192.168.1.1) and check the encryption type in the section Wi-Fi → SecurityFor maximum compatibility, please select WPA2-PSK (AES).
3. If you don’t remember the password, reset the router using the button Reset (hold for 10 seconds) and set up again.

2.2. "Getting IP address..." (endless loading)

This problem occurs when the router can't give the tablet an IP address via the DHCP protocol. The most common culprits are:

• 🛠️ DHCP service failure on the router.
• 📱 IP address conflict (another device has been assigned the same IP address).
• 🔧 The tablet has a manually entered static IP address that is not within the router's range.

Solution for Android:

1. Go to Settings → Wi-Fi, tap on your network and select “Change network” → “Advanced”.
2. In the section IP settings select DHCP (and not "Static").
3. If this doesn't help, manually enter the IP from the router range (for example, 192.168.0.100, if the router distributes from 192.168.0.1).

Solution for iPad:

1. Open Settings → Wi-Fi, tap the "i" icon next to the network.
2. In the section IPv4 settings select Auto.
3. If it doesn't work, switch to Manually and enter the IP, mask 255.255.255.0 and gateway (router address).

2.3. "Saved, WPA/WPA2 protection"

This error is typical for older tablets (eg. Samsung Galaxy Tab A 2016 or Lenovo Yoga Tab 3), which do not support modern encryption protocols. There is only one solution:

1. Go to your router settings (192.168.0.1 or 192.168.1.1).
2. In the section Wi-Fi → Security change the encryption type to WPA2-PSK (AES) or WPA/WPA2 Mixed.
3. If the router does not support WPA2, update its firmware or replace the device.

⚠️ Warning: Using outdated encryption WEP or WPA It's not safe! If your router doesn't support it WPA2/WPA3, consider replacing it - this is a data leak threat.

3. Router issues: settings that block the tablet

Sometimes the tablet does not connect to Wi-Fi due to incorrect router settingsFor example, a MAC address filter is activated, parental controls are enabled, or bandwidth is limited for new devices. Let's check these key parameters.

First, log into your router's web interface. The login address is usually located on a sticker on the back (e.g. 192.168.0.1, tplinklogin.net or my.keenetic.net). The default login and password are admin/admin or admin/empty.

If you are not sure which settings to change, reset the router to factory settings using the button Reset (hold for 10-15 seconds) and set up again. Don't forget to save your Wi-Fi password. before reset!

⚠️ Attention: On some routers (for example, Keenetic or ASUS RT-AX) After resetting, you may need to re-link to your internet provider. Check your internet provider's account for details.

4. Software failures on the tablet: network reset, updates, viruses

If the router is working properly and other devices connect to Wi-Fi without problems, look for the cause in the tabletLet's look at typical software problems.

4.1. Resetting network settings

Android and iPad have a factory reset feature. This can help if:

• 📱 The tablet "remembered" incorrect IP or DNS settings.
• 🔄 Connection errors appeared after the system update.
• 🚫 The device connects to Wi-Fi, but websites won't open.

For Android:

1. Go to Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
