That said, refer to these subsequent walkthroughs to get started. Don’t forget to test your Internet connection after performing each solution so you’ll know when to stop troubleshooting the problem.

First solution: Reboot wireless router or mode.

The very first recommendation given by your network support team when dealing with wireless Internet problems including intermittent connection or frequent Wi-Fi disconnects is a reboot on the wireless router or modem. Working on the very source of your Internet connection often leads to a prompt resolution. Just like any other devices, the router or modem firmware can also crash. When this happens, Internet symptoms start to occur. You can put the blame to your router or modem if all your devices are having the same problem using the same wireless network. In that case, you can try a router/modem power cycle solution. Here’s how it’s done:

  1. Turn off your wireless router or modem by pressing the Power button until all the LED indicators are off.
  2. Unplug the AC adapter from the power source and leave it unplugged for about 30 seconds.
  3. After the elapsed time, plug it back in to power.
  4. Then press the Power button again until all the LED indicators are on and stable.

Reboot your Samsung Galaxy J7 and all other devices that are connected to the same network.

Then try to connect to the Internet on your Galaxy J7 then see if the connection is already stable.

Note: If you see any red light on the router or modem LEDs, it denotes something is wrong and that is most likely causing frequent internet disconnects on your Galaxy J7. In this case, you’ll need to deal with and fix router/modem issue first so as to have a stable Internet connection on your Samsung Galaxy J7. For further assistance in troubleshooting router issues, contact the manufacturer or your router or your Internet Service Provider (ISP).
