Step 3. Then wait for about 5 minutes, and plug the power cable into the socket again and press the Power button to restart it.
After that, you can check if the “Raspberry Pi not showing up on network” problem is fixed.
Solution 2. Check the Ethernet Port and Cable
You also need to check if the connection is loosened or the Ethernet cable is unplugged by mistake or damaged. To do so, you can try using a different Ethernet cable on the router or connect it to another port. If you still can’t find Raspberry Pi on network, you can try updating the router’s firmware or move down to the following potential fixes.
Solution 3. Check SSID for Issues
As mentioned above, the improper SSID settings can cause the “Raspberry Pi not connecting to WiFi” issue. To check it, open your Wireless Settings window, and then go to the SSID/Wireless Network Name (SSID) section and make sure your name doesn’t have any underscores or other invalid characters. If there is an underscore, remove it and connect your Raspberry Pi to WiFi again, and see if the issue gets fixed.
