Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Your ISP typically has no knowledge of or control over your network password, so I would not expect they could verify that for you properly, it isn't their responsibility.
If you are not sure if it, I can help you determine what it is.
If you are, you may be entering it wrong, it is case sensitive and can be difficult to enter numbers, caps, and symbols on the printer properly.
How far is the printer from the router?
