DD-WRT:Wireless Packet Info - RX/TX Errors/zh-tw

Wireless Packet Info
Example: Received (RX) 72824 OK, 36413 errors Transmitted (TX) 30792 OK, 1 errors In my wrt54g if i chose the right antenna for reception and the left one for transmiision the number of error fell even if i use my bluetooth headset

How can one avoid all these errors?

 * 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.


 * 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.


 * 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.

Another important Aspect
Placing the router in the highest area possible is essential, as this will provide greater radio coverage.

For routers with external antennas, orientation of the antenna(s) is very important.


 * 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 WL-500W the middle antenna should be angled at 90°, and the other antennas should be separated at 45° angles.
