I have a feeling the same thing has happened to me. I noticed a week ago that I was no longer able to log into my router. I was planning on trying to reset the router to default settings just so I could get back into it to administer my network. If a notice was sent about the change, I'm sure it was sent to the verizon.net e-mail address attached to the account, which I don't have access to, and my roommate (whose name is on the bill) never checks.

This action by Verizon is very irritating, to say the least.
