[edit] Wireless Packet Info


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

[edit] 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.
  • If you see the RX errors constantly increasing regardless of network traffic, try the 'wl interference 2' command (via the Admin→Commands interface). This forces Wireless LAN interference mitigation to be enabled. The default of 3 (automatic) might be failing to activate despite the AP being in a heavily WiFi congested area. If this helps, you can save the command to be run automatically at boot time using the "Save Startup" button. (See also Startup Scripts.)
  • 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.

[edit] 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 WL500W the middle antenna should be angled at 90°, and the other antennas should be separated at 45° angles.
