Fix: OnePlus 9/9 Pro WIFI Not Working or Not Connecting to the Internet

2. Forget and Reconnect Wi-Fi Network

Another possible method is to remove and add the Wi-Fi network again to check if everything works fine or not. To do this:

• Go to the Settings menu on the device > Tap on Wi-Fi & Network.
• Tap on Wi-Fi > Make sure to turn on Wi-Fi.
• Choose the Network that you want to remove > Tap on Forget.
• Now, go back to Settings > Select Wi-Fi & Network.
• Tap on the specific Wi-Fi network and reconnect it to check whether the problem has been fixed or not.

3. Re-insert SIM Card

If you’re facing issues with the mobile data connectivity then make sure to re-insert the SIM card to check for the issue. It basically clears possible glitches or temporary cache data issues with the SIM card. To do that:

• Go to the Settings menu on the device > Tap on Wi-Fi & Network.
• Tap on SIM & Network > Tap on SIM 1 or SIM 2 from the SIM Settings menu.
• Now, tap on the problematic SIM 1 or SIM 2 switch to turn it off for a few seconds and then turn it back on again.

Alternatively, just use a SIM ejector pin and remove the SIM tray then check the SIM placement and re-insert it again to check for the issue.

4. Power Cycle your Wi-Fi Router

Sometimes a normal forgetting the Wi-Fi network may not come in handy. In that scenario, try performing a power cycle on your Wi-Fi Router to refresh the connectivity glitch.

• Switch off the router and unplug the power cable from the power source.
• Next, wait for around a minute or so > Plug the power cable back in.
• Turn on the router to check for the issue.

5. Check for Software Updates

If the software version becomes outdated for a while then you may experience some issues with the network connectivity or internet speed due to glitches. It’s always better to check for the software update and then install the available update. To do this:

• Go to the Settings menu on your device > Tap on System.
• Tap on Check for Updates and if the update is available, make sure to tap on Download and Install.
• Wait for the firmware update installation process to complete.
• Once done, make sure to reboot the device to apply changes.

6. Reset Network Settings

If a network configuration error is bothering you or if the above methods didn’t work for you then try resetting the network settings on the device. To do that:

• Go to the Settings menu on the device > Tap on System.
• Tap on Reset Options > Tap on Reset Wi-Fi, mobile & Bluetooth.
• Tap on Reset Settings then make sure to confirm it again.
• Now, the network reset option will start.
• Wait for the process to get completed and then restart the handset to apply changes.

7. Reset the Phone

If nothing seems working for you then make sure to perform a factory reset of your device to fix the issue. Make sure that it’ll delete the internal device data along with user settings, installed apps or games, Wi-Fi configuration, and more. So, it’s recommended to take a data backup before performing this step.

• Go to the Settings menu on the device.
• Tap on System > Tap on Reset Options.
• Tap on Erase all data (factory reset) > Select Erase All Data and then confirm it again.
• Wait for the process to be completed. Your device will reboot to the system automatically.
• Keep in mind that booting to the system for the first time after a factory reset will also take a couple of minutes. So, have some patience.
• Once booted, go through the initial setup process, and start using your device again.
