Sorry I have very little idea about OpenWrt. You can do CONFIG_ATH9K_RATE_CONTROL=y in the config file if its possible(thats how I do in compat). Its based on observation and I don't know much deep into the thing down link < up link , may be its related to rx problem people were discussing. > > On Thu, Jan 13, 2011 at 12:40 AM, Mohammed Shafi > <shafi.wirel...@gmail.com> wrote: >> On Thu, Jan 13, 2011 at 8:43 AM, Tao Jin <jintao....@gmail.com> wrote: >>> Dear all, >>> >>> I have a Linksys WRT160NL router, which has a 802.11n chip, and runs >>> OpenWRT firmware with ath9k driver.
