Did you install the driver? If one takes what you've written at face value, all you've done is just unzipped the files, and nothing else. Is that right? If yes, you must install your new driver (or .INF file) before this new software takes effect. Depending upon your operating system, you'll need to do something like the following (this for W98):-
1. Go to Control Panel, System icon, Device Manager tab.
2. Double click Modem, and highlight your previously installed modem description.
3. Click Properties, and then select Driver tab.
4. Click Update Driver - tell system where newly unzipped files are located.
After successful update, reboot PC. Whether or not you'll really notice any difference in connection speed is debatable...
