Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sender: linux-wireless-owner@vger.kernel.org List-ID: I've put 3 ath9k AR9380 NICs into a single system (core-i7). Each is configured for an AP on a separate 5Ghz channel (40Mhz wide). Individually, I can get about 300Mbps transmit towards the AP on any particular radio, but when running all together, total throughput is only about 475Mbps. I assume there is some cross-channel bleeding or similar. The APs are close by, so I was wondering if perhaps there was a way to configure the radios to be less sensitive and thus pay less attention to channel cross-talk? Any suggestions for things to try are appreciated! Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
