I received the Linksys RE6300 AC750 BOOST Wi-Fi Range Extender a few days ago, for free, via the Linksys Friends & Family Program. Our house is a two-story, 4-bedroom home so there are some areas with weak Wi-Fi reception - the master bedroom and the front room, so this would be a good test of the extender.
Upon opening the box, one notices there is only the device, a foldout card with the setup instructions, the typical regulatory information booklet, and a sheet with the tech support number. While waiting on my daughter to get ready for school, I attempted to setup the device. Scanning over the Quick Start Guide, I used the Wi-Fi Protected Set (WPS) instructions. It couldn't have been any easier. In less than 10 minutes (closer to 5 to 7 minutes) I was logged onto the extended network. The device supports both 2.4 GHz and 5 GHz bands and I had set up both of them.
Resetting the device, I then tried using the device's webpage to setup the range extender. This was also very easy as the webpage guides you through the process. There is also an aid to help you locate the device in your location for optimal performance. Once the device was set up again I ran some speed tests on the 4 different Wi-Fi connections I now had, the original 2.4 and 5 GHz and the extended 2.4 and 5 GHz in both my master bedroom and the front room.
At both locations, the extended 2.4 GHz band was comparable to the speed of the original 2.4 GHz band but the extended 5 GHz band was at least double the speed of the original 5 GHz band at that location. The 5 GHz band was faster than both of the 2.4 GHz bands at each location. Of course your results will vary from mine but I am impressed with the improvement.
I've had the extender for almost a week. During this time, I've noticed that the 5 GHz band has been consistently faster than the source 5 GHz. The 2.4 GHz extended band is sometimes faster and sometimes slower.
Overall, I'm very happy with the product. It does what it set out to do and is very easy to setup right out of the box.
