This little card, when used with the teaching tools of Linux and Windows based OS platforms, this little card works very well with both. It's maximum range capability allows my laptop to be used at over 100 feet from the wireless router. With the capability to transmit information to another (ad-hoc) computer such as a laptop the range and the Tx and Rx is far greater than 100 feet. With the Linux OS platform using in conjunction with the madwifi driver, the compatability and ease of use is dead on.If you are looking for a great product, versatility, and user friendly application of installment, then this is the product of choice.
