No internet connection on one of my devices
Sometimes you run into an issue with one particular device. It’s probably just a temporary issue. Try turning off the Wi-Fi on the particular device, then re-enabling it.
If that doesn’t work, do the same with your modem by unplugging it and then plugging it back in 30 seconds later.
If that doesn’t help, or if the problem re-occurs, consider deleting your current network from the list of saved networks on your device, then re-connect again.
If you’re running Windows 10 on a personal computer;
- Search for Wifi troubleshooting
- Open the result
- Identify and repair network issues
That will go through a series of diagnostics that may restore connectivity. On MacOS, you can run Wireless Diagnostics.
- Hold the Options key
- Click the AirPort (Wi-Fi) icon on the menu bar
- Find Open Wireless Diagnostics
- Follow the on-screen instructions
If none of that works, consider rebooting the device.
