I have observed that sometimes the TX rate of my wi card fluctuates between 11Mbps, 6Mbps and 2Mbps.Why does this happen? if its due to interference why should the TX rate be affected?shouldnt just the receiving station be affected? Was wondering if the receiving station tells the sender to slow down.does it? Another question i had is about the throughput i get and what the wicontrol command shows my TX rate is. I have seen that i get about 5Mbps throughput when the TX rate is shown to be 11Mbps.so can i assume i will always get about 5Mbps when wicontrol shows the rate to be 11Mbps? if i start getting lesser throughput then will wicontrol also be showing a lesser TX rate like 6Mbps or 2Mbps ? What i mean in short is will wicontrol automatically show smaller TX rates at the sender when my receiver throughput falls.this is related to my first question actually.
