1. Distance from the Wi-Fi router: If you are far away from the Wi-Fi router, the signal strength may weaken, resulting in a poor connection. Try moving closer to the router to see if the signal improves.
2. Signal interference: Other electronic devices, such as cordless phones, microwave ovens, or neighboring Wi-Fi networks, can interfere with your Wi-Fi signal. Ensure that your device is away from such devices or try changing the Wi-Fi channel on your router to avoid interference.
3. Router issues: The problem might lie with your Wi-Fi router itself. Restart your router by unplugging it from the power source, waiting for a few seconds, and then plugging it back in. Also, make sure that your router firmware is up to date.
4. Network congestion: If there are many devices connected to your Wi-Fi network or multiple users are heavily using the network, it can result in a slower and unstable connection. Try disconnecting some devices or limiting bandwidth-consuming activities on the network.
5. Wi-Fi settings on your phone: It's worth checking the Wi-Fi settings on your Samsung Galaxy J4. Ensure that the Wi-Fi is turned on, and your device is set to connect to the correct network. You can also try "forgetting" the network and reconnecting to it.
6. Software or app issues: Sometimes, a specific app or software on your device can cause conflicts with the Wi-Fi connection. Try restarting your phone or running it in safe mode to determine if any specific app is causing the issue.
7. Hardware problems: In some cases, there may be an issue with the Wi-Fi antenna or other hardware components of your Samsung Galaxy J4. If none of the above solutions work, it might be worth contacting the manufacturer or a technician for further assistance.

It's important to note that these are general suggestions, and the specific cause of the Wi-Fi issue can vary. Trying these steps should help you identify and resolve the problem.
