If you have a ITI branded modem from BSNL, you probably wont find much documentation about setting it up for multi-use. The unit is actually an OEM product from SEMINDIA model # DNA-A211. This how-to will show you how to setup the router so that it automatically connects to the Internet on start-up, so that you don’t have to dial a connection.
First we shall setup the DSL connection:
1. Connect to the modem/router through Wired Ethernet and enter 192.168.1.1 in the address bar. When prompted enter your username/password. It should be admin/admin by default. If you have forgotten the username/password, you can reset the modem by pressing the reset button on the back of the router with a pin for 10 seconds. If you can’t access the modem at 192.168.1.1 try this.
2. Click on Advanced Setup -> WAN. You should see the following entries. The one we are interested in is the first one as shown. Click Edit.
3. Enter the settings as shown below and click next.
Now to setup your wireless access, goto Wireless -> Wireless Bridge and choose the following:
Also ensure that your wireless is enabled by going into Wireless -> Basic:
Also ensure that your DHCP is enabled by going to Advanced Setup -> LAN and checking that your DHCP is enabled as shown below:
Now go into Management -> Save/Reboot. This will save the settings and reboot your router. On restart the modem will establish the connection and you can simply connect to the wireless network.
