Make one clean test before connecting everything
- Use e&’s setup instructions for your exact router. Place the router where it can get a good mobile signal, with safe access to power. Follow the instructions for SIM orientation and power-up.
- Check the model’s status indicators. A light for power or Wi-Fi does not by itself confirm the router is online. If the meaning is unclear, use the model’s guide rather than a chart for a different router.
- Connect one device using the Wi-Fi network listed in the setup instructions. Turn mobile data off on the test device briefly, or use a laptop without cellular data, so it cannot silently switch to another connection.
- Open a few ordinary sites. If the router and your device support Ethernet, a wired test can help you separate a Wi-Fi problem from a problem getting online. Re-enable mobile data on the test device afterwards if you turned it off.
- Once it works, secure the local network using the router’s supported settings. Do not publish the router sticker, admin password or Wi-Fi key.
If you can join Wi-Fi but cannot get online
Write down whether every device is affected, whether the status lights show a network connection, and when the problem started. If e& support advises restarting, distinguish a normal restart from a factory reset, which can erase your settings. Avoid changing APN, moving the service to a different address or repeatedly resetting the router to guess at a fix.
