What should I check if the router cannot access the Internet after powering on?
If the device cannot connect to the internet, please check the following:
Ensure the SIM card is inserted correctly.
Verify the SIM card has data service enabled and is not in arrears.
Check if dial-up parameters such as APN, dial-up number, account, and password are correct.
Ensure the computer's IP is in the same network segment as the router and the gateway is set to the router's IP.
