I, like many others, had huge headaches initially setting up this wireless adapter. I actually had to go to a friend's house and use his computer to set it up because (after a couple of hours and several attempts) Linksys Support said that my wireless router was too old to communicate with this adapter (at least for setup, not for use thereafter). However, after all the hassle of getting the wireless adapter setup, the pay off has been amazing. I haven't had any problems since the initial setup and I have used it to get both my PS3 and Xbox 360 online flawlessly. So it was pain in the butt to set up, but it has ultimately been worth it.
