Find Internet options located in the control panel. Click on the connections tab, select the ISP you want, then "set default". But be advised, that program will try to connect to the internet for all programs. Best to set it to "never dial a connection". That way you can pick and choose which program you want to use.
I have signed up for both ATT and Earthlink to check them out. Right now, I want to connect via ATT. But Earthlink keeps popping up for me to use it. Is there some way to make ATT my default ISP? I've searched XP's and ATT's help programs but couldn't find anything. Thanks, grandpaw
