Test / Review: Repeater Wifi dualband (2.4 and 5 GHz) 802.11 a/n tri-color

test-Avis-appreciation-critique-review-1 Wifi, that's fine, but unfortunately, like any wireless technology, is not as reliable as wired! You have among other things as a problem for wifi:

  • Disturbances by other appliances (microwave, etc…)
  • Disturbances on walls
  • Decline because of the obstacles
  • Decrease in flow
  • but also, decrease the scope and flow according to the standard (a, b, g, n, ac in chronological order)

  You should know that of the standard 802.11 has up to 802. 11 g, it is mainly the flow that increases. The distance also increases, but it is relatively small. On the other hand, with the advent of the 802.11 n, is flow and the distance which has increased, and the latter has virtually doubled in 2.4 GHz. Why I specify 2.4 GHz? Because it is with the 802.11 n that has appeared the frequency to 5 GHz! And where in the 2.4 GHz range has doubled, but not the flow, in 5 GHz, it's the opposite: it is the rate which was not doubled but tripled here! With unfortunately, no increase of the scope. Wholesale:

  • Side flow: 802.11 AC > 5 GHz N > N 2.4 GHz > G > B
  • Side scope: 802.11 N 2.4 GHz > G > B = N in 5 GHz = AC

  Note that the standard AC is available in 5 GHz. With this recap, we quickly notice that the scope has not changed, or very little, however because of the walls, this is reduced, especially according to the materials! In addition, we use more and more WiFi, which means that practically all bandwidths are saturated, as there are at the present time, 2.4 GHz, 3 channels with a minimum of interference, the 1, 6 and 11. The other channels competing with adjacent channels. How do I fix this? With a wifi signal Repeater! As for example that of tri-color! Dualband-repeater  

Characteristics of the dualband wifi Repeater

  • Dualband: 2.4 GHz and 5 GHz
  • Complies with IEEE 802.11 a / b / g / n
  • Dual-frequency at the same time
  • Supports router, Repeater mode
  • PPPoE / DHCP
  • QoS function that ensures the quality of VoIP and streaming multimedia
  • Wireless A / N: speed up to 300Mbps and backward compatible with 802 .11b products / g
  • Compact
  • Support WEP, WPA – SPK SPK WPA2 mixed encryption WPA / WPA2-PSK
  • Ethernet RJ45 port


The test

Small, wifi Repeater is a square that is only 7.5 cm from each side. With a WPS button to facilitate the connection with your modem without entering a code (simply press the WPS of each in a very short time for link) (but not recommended because there is a flaw in this system: If someone is there knows and scans his envir) environment continuously, it may take the WPS connection in a milliseconds instead of you, and you believing that it didn't work, you try again, except that you know, a hacker is already in your network.) Presence of 5 LEDs: 5G, 2, 4G, ON / OFF, WAN and Lan. And presence of 2 Ethernet ports (but a single cable), one for the router (WAN port) mode and one for the Repeater (LAN poWan - lanrt) mode note that of course, he cannot be both router and Repeater, because router, it sends and receives waves wif already i. Repeater router mode wifi Side options, it's still basic functions found in any Repeater. Nothing complicated. Wifi, the wifi keeps its promises, I have not noticed problems of distance on this side there. Side speed, they say it can go up to 300 Mbps, except heard that these are theoretical values, and that in reality, there are easily a bandwidth of 10 times less. But I have not noticed any decrease or increase specific compared to my tower which is also in 802.11 N. To well place the Repeater, consider placing at halfway between your router and the or you wish to have the connection, which should optimize your wifi, because more your Repeater will be far from the source, although it will send a great signal, the signal that it will return or that he will receive from the source will be of poor quality. To understand a little better, for example, 3 persons: person A is the modem, person B Repeater and person C, your computer. If person B is away from A and C, it can repeat correctly what has to C and vice versa. If B is far from A, but close to C, it can discuss without worry with C, but will have difficulty communicating with A.  


This is very Repeater work for which it was designed: modem and router! Its relative compacticite will allow it in some cases to travel with you if necessary.   Link: in http://www.amazon.fr/gp/product/B00XJBQKPG/ test-Avis-appreciation-critique-review-2
