I worked 3 days trying to find an XP modem driver for this Gateway Solo 1150. None of the Gateway driver solutions worked (as usual) so I went to the Conexant site. Carefully read the installation instructions once you have unzipped the file, and follow the instructions given there. The modem now works well, and runs stable with Windows XP. If you are running Windows 2000 or some other operating system, Conexant has other modem downloads available.
