How to repair the Samsung Galaxy A9 not connecting to hidden Wi-Fi
Problem: Hello, We have recently encountered this problem. We have both configured a hidden WLAN (SSID) and a visible WLAN on our wireless router. Once we set the SSID hidden on our mobile phone, we were able to access the Internet. But when we turn off WIFI or transfer to another SSID, we can not reconnect to the hidden SSID. We also do not find this hidden SSID in the list of available WLAN networks, but we find the SSID hidden in the list of WLAN lists being recorded that are displayed with a poor quality signal. We have seen this situation with several mobile devices such as HTC U11 +, HTC U12 +, Asus Zenphone 3, Google Pixel, Nokia 6+. And in the same wifi environment, some devices could connect properly, such as Huawei Mate 20, XIaomi. Could you give me some suggestions or workarounds to this problem? Wish to have your answer soon. Thank you so much. Regards
Solution: Before performing any troubleshooting on this phone, it is best to make sure that it is running under the latest version of the software. If an update is available, download it and install it first.
To connect to a hidden Wi-Fi network, you must add this network manually to your phone.
From a Home screen, swipe from the center up or down to access the Apps screen.
Go to Settings – Connections – Wi-Fi.
Make sure the Wi-Fi switch (top right) is on.
Tap Add Network
In the Network Name field, enter the appropriate name.
In the Security field, tap the drop-down menu icon, then the appropriate security option: None, WEP, PSK WPA / WPA2 / FT, 802.1x EAP
In the Password field, enter the appropriate password.
Make sure the additional settings (for example, EAP method, certificate authority certificate, etc.) are configured correctly (if any), then press SAVE .
If the phone can not automatically connect to this hidden network next time, proceed to the next troubleshooting procedure, listed below.
Restart the router
Like any electronic device, a reboot will update the router software and generally resolve minor issues.
Update of the firmware version of the router
It's best to make sure your router uses the latest firmware version, as it will usually have fewer bugs than the old one. You will need to refer to the router manual for information on how to update this unit.
Make sure the router settings are correct
There are cases where the problem is caused by a parameter set in the router. Refer to the router's manual for how to correctly configure the device. The items to check are the power output, the firewall and other security settings.
Resetting the router in the factory
If you have administrative access to the router, try resetting the device to the factory settings. Refer to the router manual for how to complete this step.
Once you've eliminated the router as a possible cause of the problem, it's time to troubleshoot the phone.
Reset Network Settings
Performing this step clears the network configuration, including the registered Wi-Fi networks of the phone.
In the Home screen, slide your finger up to an empty slot to open the Applications pane.
Tap Settings – General Management – Reset – Reset Network Settings.
Tap Reset settings.
If you have set a PIN, enter it.
Tap Reset settings. When finished, a confirmation window appears.
Once this is done, check to see if the problem persists.
Check if the problem occurs in safe mode
A good way to check if an application you have downloaded is causing this problem is to start the phone in safe mode. When your phone is started in this mode, only pre-installed applications are allowed to run, which makes it easier to determine if an application you have downloaded is guilty.
Press the Power button while the phone is on, then press the power button.
If the pop-up menu appears, tap Turn Off and press the option to open safe mode.
Wait a few moments.
The device is now started in safe mode
If the problem does not occur in this mode, you should find which application is causing the problem, and then uninstall it.
Wipe the cache partition
The phone stores temporary system data in a special partition, which speeds up some applications. However, this temporary data may be corrupted and cause some problems on the device. To check if this is the cause of the problem, you will need to clear the cache partition of your phone.
Turn off your device.
Now, hold down the Bixby, Volume Up and Power buttons for a few seconds.
When the Android logo appears, release the Power and Bixby buttons, while holding down the Volume Up button until the Recovery Mode screen is displayed.
You can now see the menu option of Android system recovery.
Use the volume keys to highlight Clear Cache Partition and use the power button to select it.
Confirm by selecting the option Yes
Perform a factory reset
A final troubleshooting step to consider is a factory reset. This will restore your phone to its original state. Be sure to back up your phone data as it will be erased during the process.
Access your phone's settings.
Now, scroll down and select the General Management Option
Tap on the reset option
Choose Reset factory data
Select the 'Clear all' option and wait until your device restarts with the factory settings.
Once the reset is complete, do not install any apps in your phone yet. Try to check first if the problem persists.
