Hi, Is it true that setting a really low AR5K_TUNE_RSSI_THRES value (0) in ath5k.h disables carrier sense? I find that doing so does not alter the behavior of my cards.
I use linksys wmp55ag PCI cards (atheros chipset 5213). My setup is as follows. I set two wireless networks in the same channel (5.24GHz) using two wireless APs. Two PCI cards on different machines using the ath5k driver work as clients. I send UDP traffic (iperf) from each of the clients to their respective APs. I get the same throughput through each network (about 17Mbps on either network) irrespective of the different RSSI thresholds I use. In particular I tried a scenario with one card having a threshold of 255 and the other with 0. If setting the RSSI to 0 does infact disable carries sense, I should be observing a higher throughput in the network with lower RSSI. Is there a different way to disable CS ? thanks sandeep -- Sandeep Kakumanu Presently doing PhD (Gatech Atlanta) http://users.ece.gatech.edu/~ksandeep/
