I tried to help my mom switch from Dial-up to Broadband but the computer now not working. I bought a network card and hooked my modem to this. Installed the software. But I cannot access the internet. Any suggestions? Do I need to something else to tell the computer that the modem is there? It is a pretty old computer (about 7-8 years). She does have a laptop and getting internet connection on it thru modem, so I know modem is working. I also uninstalled the dialup software as well. Thanks!!
