Fw: question

[Sandeep Agarwal]

Hi I am trying to test the performance of TCP over wireless Lans using Linux 6.1 Redhat. I am using your wvlan driver with Lucent WaveLan 11MB turbo silver cards. In the driver you have set the TX_TIMEOUT to be (4000*Hz/1000) and justify this by saying that since Ethernet is faster the timeout for wireless has to be more than Ethernet for which it is (400*Hz/1000). But since I am using 11MB cards can I use the same value of TX_TIMEOUT as Ethernet. Do you think this would improve the performance because otherwise I see a lot of retransmissions at the TCP layer. 802.11 should take care of most errors since it has acks and retransmissions unlike Ethernet but I see no improvement in the number fo retransmissions at the TCP layer by using 802.11. Do you think the TX_TIMEOUT value is causing the problem. Any help in this would be appreciated. Thanks.   Sandeep
