at my friend's place speed of evdo is awesome but the prob is that he is surrounded by tall buildings and the speed yet awesome but signal is very unstable 1 or atmost 2 bars..hence gets disconnected every few minutes,if he manages 5 mtr extension he gets 3-4bars and 800kbps average,I bought an usb extension cable for him and it works with everything but doesn't work with the evdo card and says device is malfunctioned..where as the evdo works with all other extension cables 2mtr long and all devices work with the 5 mtr cable that only gives prob with EVDO card..so both are fine but don't work with each other ,plz help about this as it is extremely necessary and might help other people also:wall:
