Welcome to the Community!
I have modified your post as it contains your account details such as the username and Customer ID for your privacy and security.
If you wish to change your Wi-Fi name & password, you will need to do it manually by logging in to your modem's interface as we cannot do it remotely. If your current modem is from us, we can have one of our Helpdesk specialist to contact and assist you in changing those details.
If you are using a 3rd party equipment, we can still try and assist however in the event that the basic troubleshooting is not successful, then you may need to contact the modem manufacturer directly.
Please let us know of your most convenient time to receive a call so I can organise a contact to be made.
