I recently upgraded my Windows 98 to XP Home. Apparantly the drivers for connecting to the internet have been erased because I can no longer connect to the internet; the computer is not "seeing" the modem. In the Device Manager under "Other Devices" two drivers are listed: PCI Simple Communications Controller, and TI RNDIS Network Adaptor. Both of these drivers show as "not working." Where can I get these drivers? And does XP Service Pack 3 contain these drivers? If so, if I purchase the CD offered by Microsoft of SP3, will this install the drivers I am missing? I am using an HP Pavilion model 4450. I exchanged the original 6 GB hard drive with an 80 GB drive that had a Windows 98 OS previously installed on it and I upgraded it to XP Home. I hope this is enough info to provide an answer. Thanks!
