Using Dlink DSL-2750U as Extending Network

Intension of this article is to use Dlink DSL-2750U as secondory router to extend network. 

  1. To Begin clean I would suggest to reset DSL-2750U router using hard reset switch on the back side of router. To do this all you need to connect your router to power supply and keep reset button pressed for few seconds. router will restart after this.
  2. Connect to "Dlink" wireless network so that you get connected to router. Access router using browser at "". Default username and password should be "admin"
  3. In case you want to configure wireless network SSID and passkey you can do at this step. Under "SETUP" tab select "WIRELESS CONNECTION". Set SSID name at BASIC section. (You will have to reconnct to router using new ssid at this point), Next setup passkey for SSID at "ADVANCE" Section. (You will again have to reconnect to SSID using passkey).
  4. Remove Network isolation this will enable connectivity between wireless and wired devices.
  5. Remove DHCP , DNS Relay. Reboot your router. 
  6. Connect ethernet cable from primary router to first ethernet port of secondary router, and you are all set to use DSL-2750U as network extender. 

(feel free to comment as this will give scope of improving article text-- post done in hurry.)
