Easy boys, if your modem is not compatable with Cromcast, you will have a alot of fun. It is not as simple as it sounds. When you start diging through your modum ie:Cisco DPC 3825 and finde out that "Ap"(acces point) is not in the modem set-up and it needs to be "DESABLED" and that is just because your ISP is a greedy basterd an will not alowe you to make this changes on your own in other words you have to phone tham up so thay can doit for you... ofcourse for a hafty price and or buy a new modum that is compatable than you will know. And our beloved Google did not bother to tell us abot this bullshit problems prior to purchasing Chromcast. As long as they made the sale, who gives a shit. I still have the unit and is not hoocked up. I really do not want to go an buy a new modem. F....k'em all nothig but bastards. I did write to Google about this, never got an answer. They could of at least tell me to F.OFF. Not even that. So have fun.
