Setup and Configuration Problems

1. How do I configure my DWR-M921 router or check my wireless network name (SSID) and wireless password (WPA key)?

   • Connect your PC to the router using an Ethernet cable.
   • Open a web browser and enter the router's IP address: http://192.168.0.1
   • Log into the router using the default username admin, the default password is admin.
   • Once logged in, you can configure your router through the GUI.

   Note: If you have changed the password and cannot remember it, you will need to reset the router to factory defaults.

   • Every PC that needs to connect to the router wirelessly, you will need to ensure you use the correct Wireless Network Name (SSID) and Wireless Password (WPA key).
   • Use the web based user interface (as described in question 1 above) to check or choose your wireless settings.
   • Make sure you write down these settings so that you can enter them into each wirelessly connected PC.

4. Why am I unable to establish an internet connection?

   • If connecting using a 4G mobile connection, make sure that you are within the network coverage of your SIM card provider, and that the service has been correctly configured.
   • If connecting using the WAN via ADSL/Fibre service, make sure the modem has been enabled/connected and is operational, and that the service is correctly configured.
