Hello Forumtalkie,
Thank you for reaching out with your questions. The question about Phone Jack installation may vary depending on if you already have our phone service or if you are a new customer looking to add phone service. If you have the phone modem set up near where you plan to place the phone or phone base, you can connect directly to the modem without needing any outlets.
It is not usual for them to take a picture of the password. It is usual for the technician to try to test the connection by connecting to your wifi network. They will use their own device if there is no other device to connect readily available. If you are concerned, you can change the wifi password at any time through the Panoramic Wifi App.

If there is a network upgrade or preplanned outage, we will normally inform our customers of the date the work will be performed at lease 2 days prior. You would typically receive a letter in the mail, email, and door hanger informing you of the date.
The purpose of the Cox Internet Forum is to allow customers to discuss technical topics related to residential Cox High Speed Internet services with other customers.
