Summary: Amazon didn't publish the specs on this so I'll just add that what they shipped was version 3. Too bad though, the image looked like version 1, which is actually what I needed and unfortunately, version 3 utilizes a different chipset that version 1, so wouldn't work with the IP phones I purchased from Arktel.
Summary: I bought this to replace the built in wireless transceiver in my laptop that stopped working. The TPlink comes with a CD to install the drivers and a TP-Link app. It was easy to install and was up and running in a few minutes and I have the fastest wireless rates I have ever had. For $13 I probably saved 100s vs replacing the built laptop transceiver.
Summary: I bought this to replace an existing unit that would drop the internet (and lately not come back). This item does the same thing. So, I'm thinking i can't totally blame the product. though, i have to admit, the setup was really easy and luckily intuitive since the instructions weren't that great. So far, its been a couple of weeks, it works most of the time.
