I bought one of these and blown away at how well it worked. I thought it was just going to be for streaming video and some browsing, but it's the best computer in my house at the moment. So, I bought another, expecting the same thing. They look alike and are supposed to have the same specs, but--and I saw reviews saying this but it didn't click at the time--the second one gave me a warning about the fan as soon as I turned it on and couldn't access wifi. Some reviews indicated that they got a dongle that connected to wife and others say they just don't have the card. I didn't get a dongle, so I'm returning. Considering buying a third, but not sure if I got really lucky the first time or really unlucky the second, and not sure I want to take the gamble.
