I'm doing a google search to locate information about the company, but found this right off the bat....
Update....I was searching while this reply was waiting to be posted, and every single link for blitzz and sub-sites that belong to them are no longer functioning and most either redirect to the marketing site or come back with 'domain' errors.
If you give your model number for your particular piece of hardware, there might be another site elsewhere we can direct you to for the drivers you need, and hopefully your hardware is reliable.
I have a BLITZZ super G wireless card, and I cannot find my disks. no prob...but when I went to the web last week, I was able to download every driver except the one for my particular card. This week, the site is gone, and you get rerouted to a marketing site. Where has BLITZ gone??!!!
