Unstable Internet connection or Wi-Fi drops in mobile devices can be due to a software or hardware issue on the network equipment and on the device itself. To rule out software problems, you will need to troubleshoot both the modem/wireless router and your problematic device. If the problem persists, then that’s when you will consider service or repair options.
Highlighted in this post are some helpful workarounds and simple solutions to a relevant problem on the Samsung Galaxy A6 2018 smartphone that keeps disconnecting from Wi-Fi network. Feel free to refer to this walkthrough whenever you need more inputs when dealing with the same issue on your smartphone.

First solution: Reboot your wireless router/modem.
The very main source of your Wi-Fi internet is the modem or wireless router (depending on your network setup). Just like other electronic devices, network equipment like modems and routers also encounter firmware crashes. And when this happens, your Internet connection becomes problematic. Various symptoms can occur when the modem/router succumbs into firmware crashes. If all your devices are experiencing the same symptoms, then that likely indicates a problem on the network equipment. As resolution, power-cycling the modem/router is recommended. This means you will need to turn the mode/router off for a few seconds and then back on. It’s like restarting a computer or your smartphone.

To do so, locate and press the Power button on your modem/wireless router to turn it off. When all the lights are off, unplug the AC adapter from the power source for about 30 seconds. After the elapsed time, plug it back in then turn the equipment on again.
Once all the equipment lights are stable, try to use the Internet on your phone and see if the problem is fixed. If it persists, then continue to troubleshoot software errors on your phone.
Second solution: Reboot your phone.
Restarting the phone can help fix minor software glitches that might have caused the Wi-Fi network connection to become erratic or unstable. It’s a simple yet very effective solution to different types of device issues attributed to software errors. If you haven’t yet restarted your phone, then do so with these steps:
- Press and hold the Volume Down button and Power button simultaneously for about 10 to 20 seconds or until the Samsung logo shows up on the screen.
- Release both buttons when the Samsung logo appears.
You won’t lose any personal information because a soft reset won’t affect saved data on your device.
Third solution: Wipe cache partition on your Galaxy A6 2018.
Temporary files and data stored as cache in the system folders can also cause similar issues when they crash or become corrupted. This usually happens after installing a new app or software update and system functions are afflicted. Wiping cache partition can therefore clear this out. Here’s how it’s done:
- Turn off the phone completely.
- Then press and hold the Power, Home, and Volume Up buttons simultaneously for a few seconds and then release the Power button when the Samsung logo appears.
- Keep holding the remaining buttons until the Android screen shows up then release.
- When in Android Recovery, press the Volume Down button repeatedly to highlight Wipe Cache Partition option.
- Then press the Power button to confirm selection.
- Wait until the cache partition clearing process is finished and you’ll see the Reboot system now option highlighted.
- Press the Power button to reboot your phone.
After your phone restarts, try to connect and see if your Wi-Fi network is already stable.
Fourth solution: Reset network settings on your Galaxy A6 2018.
If the problem persists after wiping cache, performing a network settings reset can be the next option to consider. This will clear all your current network settings including Wi-Fi networks and Bluetooth connections. Any erratic or corrupted networks or settings that might have caused conflict with the Wi-Fi network in use will also be removed. Simply follow these steps to do so:
- Tap to open Settings app.
- Go to General management section.
- Tap Reset.
- Select Reset network settings from the given options.
- If prompted, enter your device password or PIN to continue.
- Then tap Reset settings to confirm.
Your phone will restart by itself when the network settings reset is finished. By then you can set up and reconnect to your Wi-Fi network as if it’s the first time you join.
Fifth solution: Restore factory settings on your Galaxy A6 2018.
As your last resort, you can do a master reset or restore your Galaxy A6 2018 to its factory defaults. This is often recommended to deal with persistent software issues on the phone. But you have to note that this will delete all your saved files and data from your phone. Any tough bugs and complex system errors that might have caused network problems will also be wiped out in the process. Should you wish to proceed with a factory reset, back up all your important data then follow these steps:
- Tap to open the Settings app.
- Navigate to Cloud and accounts.
- Tap the option to Backup and restore then turn on Back up my data and Restore options, if necessary.
- Go back to Settings-> General management menu.
- Then tap Reset.
- Select Factory data reset from the given options.
- Then tap Reset device.
- If prompted, enter your password or PIN to continue.
- Then tap Delete all to confirm reset.
You can also reset to factory defaults through Android recovery. This option is recommended if your phone is not responding and reset via settings menu is not possible. After the reset, you will need to set up your device and enable necessary features including Wi-Fi, to use them again on your phone.
Usually, software problems are resolved by a factory reset. To see if it does, try to connect to your Wi-Fi internet and see if the connection is already stable. If the problem continues, then you’ll need more help.
You can contact your Internet service provider/carrier to report the issue and ask further assistance. Also have them check their outage boards for any ongoing outages that might have caused network service disruptions in your place. If possible, you can ask them to provision your wireless router/modem again to refresh your Internet service from their end.
Alternatively, you can escalate the problem to Samsung Support for other options and official recommendations. This should be considered among the last options if the problem started after installing a new software (Android) update on your Galaxy A6 2018 smartphone. In that case, intermittent Wi-Fi connection can be tagged among other post-update issues requiring a fix patch.
