How to fix your Android phone when it can't connect to a wireless network

Initial Check

Before delving into more technical solutions, it’s worth performing some preliminary checks on your Android phone:

1. CHECK YOUR WiFi CONNECTION: Make sure other devices can connect to the WiFi network. If they can't, the problem may be with your router or Internet service provider.
2. Restart your device: Sometimes, a simple reboot can solve many technology-related issues. Turn your phone off, wait a few seconds, and then turn it back on.
3. Forget and reconnect to a network: Go to your WiFi settings, select the network in question, and select "Forget." Then, reconnect by entering your password again.

If these steps don’t work, it’s time to dig deeper.

Advanced Troubleshooting

1. Check for system updates

Outdated software often causes connection issues. To check for updates, do the following:

1. Open your phone's settings.
2. Scroll down and click "System".
3. Click "Advanced" (this may vary depending on your version of Android).
4. Click "System Update".
5. If an update is available, download and install it.

2. Reset network settings

Resetting network settings can solve WiFi, mobile data and Bluetooth problems. The method is as follows:

1. Open the settings of your phone.
2. Click "System" and then "Reset Options".
3. Click "Reset WiFi, Phone and Bluetooth" or "Reset Network Settings".
4. Click "Reset Settings" to confirm.

Note: This will clear all network settings on your phone, including your saved WiFi networks and paired Bluetooth devices.

3. Check the MAC address of your Android phone

Some routers restrict access based on the device’s MAC address. If your MAC address is not recognized, you will not be able to connect. To check your phone's MAC address:

1. Open your phone's settings.
2. Click "About Phone".
3. Click "Status".
4. Look for "WiFi MAC Address".

If your MAC address is unavailable or looks unusual (such as 02:00:00:00:00:00), you may need to contact your device manufacturer or service provider.

4. Use Safe Mode

Safe Mode allows you to check whether third-party applications are causing WiFi issues. To start your phone in safe mode:

1. Press and hold your phone’s power button.
2. Click and hold the "Shutdown" option until you see the "Reboot to Safe Mode" prompt.
3. Click "OK".

If your WiFi is working in safe mode, it may be an application you installed that is causing the problem. You can uninstall the apps one by one to find the culprit or perform a factory reset to start fresh.

5. Factory reset

If all else fails, factory reset may be your last resort. This will delete all data on your phone and restore it to its original state. Before proceeding, make sure to back up important data.

1. Open your phone’s settings.
2. Click "System" and then "Reset Options".
3. Click "Delete all data (restore factory settings)".
4. Click "Reset Phone" to confirm.
