Some wrote that the unit could be set up. I have to disagree. CD in a laptop slide which is already in the W-Lan, a few clicks to finish. I can not say what would have been without a laptop, and I first looked strange, but good enough in my household laptops are available therefore not an issue :)
After setting up the equipment brought to the desired location and turned on. The 2 rooms, which should be improved with the range have gained much at reception. Bedroom of 1-2 bar to full 4, kids 20% signal strength on 60-80%. By contrast, my Netgear looks repeater from old who is actually still a meter closer to the bedroom and provides only the 1-2 bar.
Now I can finally stream into the bedroom and my son also has no problem with too weak reception more. I'm sure now throw out the Netgear and replace it with another Linksys :)
