Wi-Fi Ranger Extender Needs More Power 07/23/2013
This review is from: D-Link DAP-1320 IEEE 802.11n 300 Mbps Wireless Range Extender - ISM Band
This is a very portable, very small (a 2" x 2" x11.75" cube shaped power plug), and relatively easy to setup Wi-Fi Range Extender - no cables, you simply plug it in the wall. Signal strength was stronger when routed via Range Extender over a limited range of testing positions. Has a lot of potential but it needs to reach farther and work faster.
In no case was the download speed faster with the Range Extender than with the primary Linksys E-2500 Wireless Router (on 2nd floor) at any tested point in a 4 floor house (basement, floors 1, floor 2, and attic). Although relatively easy to setup, the instructions are unclear -not unusual for devices of this type.
This was a difficult piece of hardware to test and analyze accurately and was done over several days. First I checked the signal strength using my Android Tablet with Wi-Fi Analyzer v 3.6 (by farproc tools). My Linksys E2500 was on the 1st floor (4 stories with basement designated as Floor 0, Floor 1, Floor 2, and Floor 3 (attic) for simplicity) in the Living Room which is toward the front of the house. I plugged the D-Link DAP1320 into an AC outlet on the 2nd floor of the Kitchen (horizontal distance of 25 ft, and vertical distance 8 feet), and measured the Signal Strength at two different locations (at, above, or below, the Kitchen, and Living Room) on each floor, when connected to either Linksys Wi-Fi and then switched to the D-Link Wi-Fi Range Extender.
Next I measured Download and Upload speeds with a Windows laptop computer using the speedtest.net web utility first connected with the Linksys and then the D-Link Wi-Fi at all of the same locations (2 positions [Kitchen and Living Room] on each floor). For comparison my WIRED Download and Upload speeds were 24-25 Mbps and 2.1 Mbps, respectively. As with every ISP the wired speed varied a bit with the time of day, therefore, for the Wi-Fi testing, which varies more than the Wired connections, I took 3 or more readings at every test position and calculated the mean and standard deviation. For the sake of clarity and simplicity I took the ratios of the signal strengths and the Download speeds and base my conclusions on these derived measures. I will not present Upload speeds because at every position with either Wi-Fi source these were always between 2.01 and 2.09.
Signal Strength measured in the Living Room position was stronger on every floor in the 4 floor home with the Linksys Wi-Fi connection than with the D-Link Wi-Fi Range Extender even though the Signal Strength was a bit higher in some locations with the Range Extender.
