Maybe it still is Lower the Fragmentation threshhold; Add a RTS/CTS Threshold; Lower beacon interval; Increase dtim_period to 3; If it's a congestion problem, it may be that some devices cannot be heard during the hourly rekey, changing the period from one hour to 24 hours will decrease the chances of this (option wpa_group_rekey '86400') 参数. 11r; 802. 5k次。分片阈值 MAC层的帧分段，是由分段阈值（fragmentation threshold）这个变量所控制。任何大于分段阈值的帧都会被分割为较小的单位，再加以传送。分段阈值的默认值是2346，或物理层所容许的MAC帧最大长度。不过，RF物理层所使用的MAC帧长度通常是4096个字节，因此这个参数通常默 openwrt配置好ap之后，使用过程中经常出现网络卡顿，ping测试后发现，网络抖动很厉害,不是会有丢包发生。反复测试后发现2个参数设置之后可以明显改善网络的质量。 Fragmentation Threshold ：2346 RTS/CTS Threshold ：2347 设置好之后发现网络的瞬间变稳定，延时也减少了 This is a read-only archive of the old OpenWrt forum. pem in a tar. 07.
