Posting this again because the first one disappeared. I live in Nevada and I have identical issues with Cox. They always wanting to send a technician out to fix the problem and charge me $75. I fell for it the first time, but when the tech arrived I watched him. He did absolutely nothing. The issue was fixed when he called into the tech office. The problem was on their end but I got billed anyway. Since then I have moved once, and returned from seasonal hold once, and both times the same issue. They refuse to correct the settings on their end, and instead want to send out a tech at my expense. Honestly i think the Techs know less than I know at this point. I am not an expert but I know how to read a router page and when I post the errors here . . and ask for help in diagnosing them . . .the post gets deleted as spam! Nice.
