this is to improve on the attempt that i made yesterday, to inform you of this" Super Modem,"(imo) as i said, i've tried them all. to start with, the USB720 looks very simular to the old PC and Express Cards. the big difference is you no longer need a PC or Express Card slot. you could install the USB720 into a USB port and it would work about the same as the Express Card. BUT, another improvement is the USB Extension Cable. it is Y shaped with 1 female and 2 male connection ends. the USB720 plugs into the female connection. plug the #1 male connector into a USB port, on the computer, and you could be ready to get online. but, if you plug the #2 connector into another USB port you will get a power boost that will help in weak signal areas. BUT WAIT! THERE'S MORE! i'm in a very weak signal area, so i went ahead and bought the 10' antenna cable. ($20) and the necessary cable adaptor. ($10) so, forget DSL and WIFI. what i have is as good as it gets!
