This removable USB wireless adapter is remarkable. Its high gain is much higher than the wi-fi PCI cards. I was amazed at its performance by comparing with internal D-LINK Wireless. Its installation is fast: first the driver on the CD and then the adapter into a USB port. It is recognized immediately. We enter the WEP key (or WAP) and voila. It surfs the net with great ease. Inserts and withdraws smoothly like any USB drive. Excellent value and well presented. I highly recommend the purchase of this product.
