Test Environment:
Freebox and the Netgear router is installed on a high shelf in a closet at the entrance, where happens the adsl. The test machine is on the 1st floor 7m straight. By cons separated by a concrete slab about 25 cm, the floor of the first floor.
IT environment:
Equipment:
- An HP N54 server with Ubuntu-server connected to 1Gb wired to the router Netgear R7500
- A machine with Mac OS X and Windows 7 (Test performed on both SE story that the drivers for the wireless card "BCM4352" are not in causes)
On the software side, I used iperf server on Ubuntu and Mac OS X client on "10.8.5" and Windows 7
Unfortunately, it did nothing. Besides, I left the wifi Freebox V3 (2.4Ghz N) issue, just to compare. Well Freebox emits between 5 and 10 dB higher, signal received at -55 dBm for the router from -60 to -65 dBm. Yet the Freebox has no external antenna. For the 5GHz band, I have nothing comparable.
The first test showed a flow rate of 2 to 5 MB / s (16 to 45Mbps) over the band of 5GHz. Signal received at -70 dBm. On the 2.4Ghz band flow is mounted between 9 and 10MB / s (72 to 80Mbps).
The second test with the router upstairs to about 7m from view test machine showed a rate of 40MB / s so about 320Mbps in 5GHz band (see photo). What is decent but far from theoretical performance. The received signal was about -45dBm in 5GHz band (see photo) and -35dBm 2.4Ghz band. There, the result is quite satisfactory, but the router is almost next to me (;-)))
I also tried with an iMac (next to the test machine). 2008 iMac accepting (already (;-)) in the 5GHz 802.11n 300Mbps. The result is very good in relation to the capacity of the wireless card.
Now, when the signal received from the router drops "above" about -50dBm, the bandwidth drops quickly enough and above is not necessarily very stable.
That said, I have pretty much the same damage with other routers. The ceiling is perhaps one of the reasons ... Or router performance are those announced or is it clamped to transmit power and as soon as there is an obstacle the signal drops quickly ... it's may be true for all wireless routers out today ???
That said, I repeat, with the Freebox, I capped at 9MB / s therefore 72Mbps 2.4Ghz band, I was entitled to expect better throughput when reading the OEM specifications hopefully a real gain above compared to a freebox a different age ...
Product returned.
