I have dial up and sometimes the icon on task bar shows my computer is on but I can't access a site. It says check adapters. When I went into device manager, 4 of 6t04 and microsoft 6 to4 adapter #19 say that the latest adapter are installed. Then under properties it says This device is not working properly because Windows cannot load the drivers for this device Code 31. Is this normal and what can I do about it?
