My D-Link DSL-2642B's wireless connection keeps dropping. The LAN connection is fine however the wireless seems to drop randomly (Or when the traffic on the router is high).

Running firmware:
Current Firmware Version :   AU_2.10
Current Firmware Date :   20101006

What I've done:
  • Allocated DHCP Reservations for all devices
  • Noticed system log has Wireless Errors http://imgur.com/9tNJeBm
  • Called ISP and they 'Reset the router on their end'
  • Changed router channel to 4 (Lots of routers in this area)

We have around 5-6 devices on the network at any one time. The dropouts occur if we are downloading/listening to music/doing anything other than looking at static webpages (Exaggeration but thats what it feels like). I have to unplug the router and replug it for it to restart and allow us to reconnect.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • What wireless devices do you have connected?
  • Ensure any devices with WiFi adapter drivers are updated.
  • Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many? Use v3, its free.

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
