If you find one in a bargain bin or still have one in your drawer, do not throw it away. With the correct drivers and a little patience, the BlueSoleil 703590 is still capable of breathing wireless life into the oldest of desktops. As of 2025, IVT Corporation’s official support for BlueSoleil 6.x/8.x is limited. Always scan downloaded drivers for malware.
