最基本的物质需求得到满足之后，唯一能够不断增加个人幸福感的事情就是帮助他人

• Do a site survey under Status -> Wireless and find out what channels in your area are NOT being used and set it in your Wireless Basic configuration. Also setting the wireless Channel to Auto will dynamically config the channel and channel width. Much more user friendly feature for basic users.将dd-wrt路由器的WI-FI频率设置为未被周围无线路由使用的channel，或设置为自动模式，Windows下的inssider是个很好的WI-FI频率分析工具。

• Selecting an unused channel works, but one must choose a channel that is two channels (10Mhz) separated from the the adjacent occupied channel. There will still be interference with one channel separation.为路由器选择一个未被占用的channel，且最好与周围被占用频道相隔两个channel（即10Mhz），相隔一个channel仍会产生干扰。

• The bottom line is that the high RX error rate is due to Radio interferences from neighboring Wi-Fi, Bluetooth, Cordless phones, Cellular phones, Speakers, Microwave Ovens, Fans, and even Florescent lamps. If this is happening to your AP, you may want to tweak the Channel, Bluetooth coexistence mode, and dissociate the AP from any sources of interference.调整周边环境，包括蓝牙、无绳电话、手机、扬声器、微波炉、风扇、荧光灯等，尽量减少干扰源。

根据情况调整路由器天线摆放角度也有一定效果，做法如下：

• For Single antenna models, it should be placed 90° (L Shaped) with respect to the flat side of the router.

• For Dual antenna models, the orientation should be 120° (V Shaped) with respect to the flat side of the router.

• For Multiple antenna models, they should be oriented at 45°. (W Shaped) For example, on an Asus WL500W the middle antenna should be angled at 90°, and the other antennas should be separated at 45° angles.
