i agree about connecting to the modem directly, if your act light is flashing it means its connected to the switch. could be a bad switch, or again, dsl is pretty touchy with other phone calls and such. The only way i would use dsl is with a separate line ( had dsl and phone service on same line using filters, and internet was always down and the quality on the phone sucked. ) that could have been ****ty service too... gotta love qwest
