I want to transfer my desktop computer to another room but i dont have any phone outlet port on the wall, so I purchased SBC wireless phone/modem jack consist of base & extension unit that can plug-in to electrical outlet & convert to phone/modem functions. I followed installation procedure for this unit but I can't log-in to SBC DSL internet however there was a dial tone. I contacted many agents for SBC DSL center but the reply were not clear enough to solve the problem, some said they dont have experience to deal with wireless phone / modem jack system like mine.
