Our Rok500 500mW USB Wi-Fi adapter has been discontinued. The product launched on March 27, 2009. As newer, better, and more powerful products are developed, it is necessary to discontinue older models. Any Wi-Fi product model you see on a store shelf will likely be discontinued by the manufacturer within 1-2 years of release date depending on what it is (accessories that can be used with various products have a longer shelf life). It does not mean there is anything wrong with the product, it is just time to make room for the next best thing.
We will continue to offer support for any owner of the Rok500 for one year from the original purchase date.
If you ended up here in search of a Rok500, we recommend getting the Alfa AWUS036H 1000mw USB Wi-Fi adapter. This is a well reviewed product that gets great range and strong signals.
