      Did you try installing the latest drivers for this adapter?

      I see a list here:


      According to the specification these adapters use a PHILIPS 87C52 chipset. I am not sure if you can find a 3rd party driver that is perhaps better than the Belkin driver.

Its been working fine for several years, but December of 2010 it became unreliable breaking comm between station and PC after a period of time. A restart of WUHU is required to correct. The driver is the latest one and is the same driver I have been using. I've uninstalled and reinstalled the driver. It was published in 2007.
