I have Fortinet FAP220B access point supports 802.11n.
I have 3 laptops in testing.
pc1 is connected to FAP through wirless at 100Mbps.
pc2 and pc3 are connected to FAP wirlesslessly using 11n 5GHz. Channel bonding is enabled on both FAP and pc2 and pc3. The Windows show the wireless connection speed is 270Mbps on pc2 and pc3.
There is no radio interference in the test environment.
I use iperf to test the throughput.
pc1: run iperf -s
pc2: iperf -c <pc1>
The throughput is only 20-30Mbps.
Q#1. Why throughput is 20Mbps not somewhere around 100Mbps?
pc2: run iperf -s
pc3: iperf -c <pc2>
The throughput is usually around 15Mbps.
Q#2. Why the throughput is not around 150Mbps?
I researched the Internet and found out someone can get around 100Mbps wireless throughput using 11n.
Please comment on my test results and share your experience on 11n performance.
Thanks a lot.
