First off, 170$ a month is less than 6$ a day. If you are in an outage, and they offered you 17.63, smile and shut it.
Second, WiFi is a function of a wireless router, not Cox Cable. You may be RENTING their Pano modem, and if that's the issue, go BUY your OWN modem and router, and that way Cox is responsible for providing you a signal to the modem, and if you need help with WiFi, you can pay separately for that, since YOU would own the equipment, and be responsible for setting it up and using it.
I have had Cox internet in my home for over 25 years, and I have been more than satisfied with product, and their service. MAYBE you should try being nice, and that way someone may WANT to help you.
