First of all, please connect the network cable directly to the computer, and try dialing up the Internet through the computer to see if the same error still occurs. If the same error is reported, it is recommended that you call the 10010 customer service hotline and provide the ID of the account holder, and the staff will change your password for you. If the computer can dial up normally, please make sure the router password is entered correctly, paying attention to the capitalization. You can also restore the factory settings and then reset the wireless account and password. Finally, it may be that your account is hung up on the operator's server because it is not disconnected normally. You can call the 10010 customer service hotline to disconnect it for you.
