I didn't have an issue with my older modem, but sure send me a free upgrade, the xFi Wireless Gateway. Ok everything works fine, internet, wifi, TV... no phone. I called customer service, I need to plug my phone into the back of the new modem? What? I didnt have to do that with the old one.

No sir, my closet phone jack is down the hall in another room. No sir I'm not moving my new modem and my PC on ethernet and my desk to that room. MY PHONES WORKED BEFORE THROUGH MY WALL JACKS!! Seriously sir I have to plug a wall phone into the back of the new modem? Sure fine, yes, the phone works but now my other phones connected to my home phone jacks don't work.  This is an upgrade? Why did my phone jacks work before and now they don't? I don't think he understood what I was saying or is it not possible anymore to use my home phone jacks with this new upgraded modem?
