This is where DELL keeps its Customers UP&RUNNING..
The Conexant Modem uses a complete CD-install w/NO Updates..
If you purchase a New Non-DELL Modem your in need of Registration and Updates..and if the Update is a ZIP File..your going to need that UPDATE from Windows..
So a new modem requires consideration..
I use my DELL Modem to re-install my PC..and then un-install it for my USROBOTICS 5669B/modem..and need the Microsoft Update service to get that Update FILE to open..and I pull my RAM down to 512MB's for re-Installs..and add the second Module later that day..and all VIRUS Scanning MUST be turned off for working inside ADD/REMOVE Programs..firewalls are mostly OK.
