Tell your Computer Service people to set this in the Modem it self as connecter Permanentalt then you will not be disconnected. This is ffor if yyou have an unlimited plan. You can find this Modem Settings in Control panel in Modem.

I had the same problem but it is corrected as above by the Computer service peoplr.
