Wireless internet with digital phone.?

[Tony]

I have time warner cable and I want to get wireless internet. (right now I have wired). I also have digital phone and it says on the website that wireless does not work with the digital phone modem, so I will have to buy a speicalty modem with wireless built in and people come in to set it up. How much will this cost and how much extra, if any, will it cost per month
