Networking via access point and bandwidth issue
 

Hi all,
I am new to networking as a whole. I have configured a accesspoint (asus wireless AP WL-330gE) in gateway mode. It has 3 clients now.

AP
1----2-----3

1 is connected via RJ45 ethernet, 2 and 3 via wifi to AP. The wifi based clients have Managed mode and use IEEE 802.11abg. The access point is working on IEEE 802.11b mode (Bandwidth upto 11Mbps).

Now, I wanted to try checking the TCP bandwidth with iperf command.

The bandwidth between 1---AP----2 was 4.38 Mbps
The bandwidth between 1---AP----3 was 5.39 Mbps
The bandwidth between 2---AP----3 was 2.97 Mbps

I don't actually get the pattern of bandwidth drop in all these communication links. Could anyone explain me why is the bandwidth for each case so low?

Thankyou
