Excerpt: Lightening tickled the computer and after> no ethercard worked after / NO CONNECTION ! ! ! Went to Staples and picked up Linksys AE3000 Dual Band N900 USB Adapter by Linksys. Haven't missed the internet since. If your Ethernet Card goes, try it. I have found Linksys a true solution to all my internet connection problems.
Summary: I found the AE3000 to be an excellent device. It is fast and has a blue light that tells you it and the installed driver is working. You must install the driver for this to work properly. When using this device, you must make sure it is the currently connected one. Also, you can tweak the speeds by going into Device Manager and change the "Gaming" option for the driver (Network adapters->Linksys AE3000; double click and select Multimedia/Gaming Environment).
Excerpt: Great performance at a great price. I especially like the external cradle which removes the adapter from the immediate space around the other system units thus providing clearer communication with the household router. The adapter was put on my wife's PC to replace an older adapter and she saw a major improvement in speed.
Summary: Works great in my apartment in the next room. No issues whatsoever and I have had it for about 2 weeks. My internet is actually faster than my macbook pro's wireless. I have CenturyLink and use an airport extreme for my router. It was very easy to set it up. Just put in the install cd, plug in the adapter, and then you are all set.
