1. Restart your phone and router. This is a simple solution that often fixes Wi-Fi problems.
2. Move closer to your router. The closer you are to your router, the stronger the Wi-Fi signal will be.
3. Check for interference. There are a number of things that can interfere with Wi-Fi signals, such as microwaves, baby monitors, and cordless phones. Try to move your phone away from any potential sources of interference.
4. Change your Wi-Fi channel. If there are a lot of other devices using the same Wi-Fi channel, it can cause congestion and weaken the signal. You can change your Wi-Fi channel in the settings of your router.
5. Forget the network and reconnect. Sometimes, simply forgetting the network and reconnecting can fix Wi-Fi problems. To do this, go to Settings > Wi-Fi > Advanced > Manage known networks and find the network you're having problems with. Tap on it and then tap Forget. Once you've forgotten the network, you can reconnect to it by entering the password again.
6. Update your phone's software. Software updates often include fixes for Wi-Fi problems. To check for updates, go to Settings > System > Software update and tap Check for updates.
7. Reset your phone's network settings. This will reset all of your phone's network settings, including Wi-Fi, Bluetooth, and cellular data. To do this, go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth and tap Reset settings.
8. Take your phone to a service center. If you've tried all of the above and you're still having problems, it's possible that there's a problem with your phone's hardware. In this case, you'll need to take your phone to a service center for repairs.
