Why Wi-Fi on my tablet has turned gray: 5 main reasons

A gray (or translucent) Wi-Fi indicator means the wireless module is It's on but can't connect to the network.This differs from Wi-Fi being completely disabled, where the icon is missing or crossed out. Here are the key causes of this issue:

• 🔄 Operating system failure — a temporary glitch after an update, overheating, or prolonged operation without rebooting.
• ⚙️ Incorrect network settings — the saved router parameters conflict with the current ones (for example, the encryption type has changed).
• 📡 Problems with the router — DHCP failure, enabled parental access control, or MAC address restriction.
• 🛠️ Corruption of system files - after an unsuccessful update or installation of questionable applications.
• 🔋 Energy saving - on Android, some manufacturers (for example, Xiaomi or Huawei) aggressively disable background processes, including Wi-Fi.

Less often guilty hardware malfunctions: antenna failure, oxidation of the Wi-Fi module contacts, or failure of the wireless chip. Such cases are usually accompanied by other symptoms, such as the tablet not detecting not a single network or overheats in the area of ​​the top cover (where the antenna is located).

Method 1: Basic diagnostics – checking the router and tablet

Before digging into the settings, rule out obvious causes. Start with the router:

1. Reboot your router (unplug it from the power outlet for 30 seconds).
2. Check if other devices (smartphone, laptop) work with the same network.
3. Make sure the light on the router is not on. WPS or Wi-Fi red - this is a signal that the network is blocked.

If everything is fine with the router, move on to the tablet:

• 🔄 Restart your tablet - press and hold the power button for 10 seconds (on iPad without home button: simultaneously Power + Volume Up).
• 📶 Turn Wi-Fi on/off 3-4 times in a row in the quick settings panel.
• 📍 Check the airplane mode - sometimes it is activated by accident (on Samsung may turn on when the battery is low).

If Wi-Fi works after these steps, the issue was temporary. If not, read on.

Method 2: Reset network settings (without data loss)

Grayed-out Wi-Fi often occurs due to a conflict between saved network settings and the current router settings. For example, if you changed the router password, but the tablet is trying to connect using the old settings. Resetting the network will delete all saved Wi-Fi and VPN passwords, but will not affect personal files or apps.

For Android:

1. Open Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
2. Confirm the action (you may be asked to enter your PIN).
3. Restart your tablet and try connecting to the network again.

For iPad:

1. Go to Settings → General → Transfer or reset iPad → Reset → Reset network settings.
2. Enter your Apple ID password if prompted.
3. After rebooting, select the Wi-Fi network and enter the password.

If the tablet still won't connect after the reset, check if the MAC address filter is enabled on the router. In this case, you should either disable filtering or add the tablet's MAC address to the list of allowed devices (you can find it in Settings → About tablet → Status → Wi-Fi MAC address).

Make sure you know the passwords for all Wi-Fi networks you use.

Write down your VPN settings (if you use one)

Check if there are any important devices in the Bluetooth list (such as a keyboard)

Disable the SIM card if the tablet supports mobile Internet-->

Method 3: Update firmware and Wi-Fi drivers

Outdated software is a common cause of gray Wi-Fi. Manufacturers regularly release patches to fix connection issues. For example, Android 12 there was a bug that caused tablets Samsung lost connection to 5 GHz networks.

How to update Android:

1. Open Settings → System → System Update.
2. Click Check for updates and install the available ones.
3. If the update is not found, check manually on the manufacturer's website (for example, for Lenovo Tab — support.lenovo.com).

For iPad:

1. Go to Settings → General → Software Update.
2. Download and install the latest version of iPadOS.

If Wi-Fi doesn't work after the update, try roll back the firmware (Applicable to Android). To do this:

1. Download the old firmware version from the official website (for example, for Xiaomi Pad — miui.com).
2. Install via recovery mode (Power + Volume Up).

⚠️ Attention: Firmware downgrade may result in data loss. Please back up your device beforehand. Settings → System → Backup.

Method 4: Changing DNS and IP settings (for advanced users)

Sometimes gray Wi-Fi is caused by IP address conflicts or issues with the router's DNS servers. By manually entering alternative DNS (for example, from Google or Cloudflare), you can bypass ISP blocks or outages of the default servers.

How to change DNS on Android:

1. Open Settings → Wi-Fi.
2. Click on your network → Change network → Advanced settings.
3. In the field IP settings select Static.
4. Enter:

   DNS 1: 8.8.8.8
   DNS 2: 8.8.4.4

   (this is Google's DNS) or

   DNS 1: 1.1.1.1
   DNS 2: 1.0.0.1

   (DNS Cloudflare).

5. Save and reconnect.

For iPad:

1. Go to Settings → Wi-Fi → (tap the "i" next to the network).
2. In the section DNS select Manually and add servers (as above).

If Wi-Fi works after changing the DNS, the problem was due to blocking by the ISP or a failure on their DNS servers. To revert to automatic configuration, select Receive automatically in IP settings.

What should I do if I can't save a static IP?

On some tablets (eg. Huawei) the field for manual DNS entry may be blocked. In this case:

1. Install the application DNS Changer from Google Play.

2. Select it Custom DNS and enter the addresses 8.8.8.8 and 1.1.1.1.

3. Activate the VPN mode in the application (it is needed to apply the settings).
