WiFi does not work on Samsung Galaxy S9 [Solution]

How to solve WiFi connection problems on the Samsung Galaxy S9. The resolution of WiFi connection problems on the Galaxy S9 is always complicated. The reason for this is that it is difficult to be sure that the problem derives from the smartphone or WiFi connection you are trying to connect to. But fear not! We're here to help you understand it.

Before executing any troubleshooting procedure on the S9, we want to check if other devices are able to connect properly to the WiFi. If other devices seem to have problems connecting to the WiFi in question, it is likely that the problem is not with your Samsung device but with your WiFi connection. 

In this case, we recommend contacting your Internet provider for assistance in troubleshooting.

If your Samsung Galaxy S9 seems to be the only device with WiFi connection problems, here are some simple steps to solving the problems you may experience.

The first step is to delete the WiFi connection from your smartphone by performing the following operations:

  • Go to Settings> Connections> Wi-Fi
  • Select your Wi-Fi network and touch Forget

This will erase the WiFi connection and settings from your Galaxy S9. The next step is to restore network settings. This does not delete any data from the smartphone but also restores the WiFi settings.

  • Go to Settings> General Management and tap Restore
  • Select Reset Network Settings
  • Turn off your Galaxy S9, then turn it back on

After restoring the network settings and rebooting, you want to reconnect to your WiFi and test it again by uploading a web page or app. If you can connect properly, you can stop here. However, if you continue to experience problems with your WiFi, continue reading.

  • Restart the WiFi modem by proceeding as follows. Sometimes the problem is still from the modem even if only your Galaxy S9 is affected:
    • Disconnect the Internet modem from its power supply which is usually located behind it
    • Wait 30 seconds
    • Reconnect the Internet modem to its power adapter
    • Wait 5 minutes for the modem to start up completely
    • Try reconnecting with your Samsung Galaxy S9
  • If your Galaxy S9 still has problems, sometimes the operating system may be the source of the problem and you want to make sure it's up to date in Settings> Software Update.

There are no other settings to check that could help you solve the WiFi problem, but you can try performing a factory reset. 

It is necessary to keep in mind that performing a factory reset will restore your Samsung Galaxy S9 smartphone to its default state and delete all personal data, then back up photos, contacts and whatever else is required before a restore factory.

If you have tried all of the above but are still having problems with your Galaxy S9 on all WiFi connections, the problem could also be hardware related. In this case, consider having your Samsung smartphone repaired or replaced by your operator or manufacturer.

If connection problems persist but only with a single WiFi network, you can try changing the configuration of that network if it is your home network. You can try changing the WiFi channel or changing the encryption for the WiFi password (from WPA2 to WEP). 

If you are not sure how to do this, the best solution is to contact your Internet provider and ask them to help you.
