content: I was attempting to set up a desktop comptuer running Windows XP in a room separate from my office. I originally bought the Linksys PCI adapter and it never installed properly. After 6 hours on the phone with text support and 2 PCI units, I was recommended to try this unit by a sales person at the store. I brought this home and installed it. It was very simple to install and detected my router. However, it would not connect to my router. After another 3 hour with text support (who were clueless people and had very poor customer service) with this unit, I decided to return the WUSB11 and decided that maybe wireless was not going to work with this particular computer and decide to go with the Netgear XE102 Powerline Adapter. Which, I highly recommend if you are setting up a desktop or a computer that does not need to be mobile. Linksys puts out poor products and equally poor customer service. I will never buy another Linksys product if I do not have to.
