Okay, Ive been asked by a lot of friends and classmates, to help me configure their modem with Linux. So here goes. This is a guide for Starcom UT300R2U.

Goto your browser and in the address bar, type in “192.168.1.1″ (without the quotes).

In the login window that appears, type in “admin” (without the quotes) for the username and password. That’s right, both are the same.
uid:admin; pwd:admin
Now you will encounter a window, with various links in a pane on the left side, and a table giving some device information. Click Advanced Setup in the left pane and you will come across such a table.

Click the Edit button on the first entry. According to your current configuration, the displayed table may differ by a few entries, but its inconsequential, because we are editing and making a new one.

ATM PVC Configuration: Enter the following: 0 in the VPI textbox and 35 in the VCI textbox. Disable the”Enable VLAN Tagging” checkbox. Service Category must be UBR without PCR.
ATM/PVC config.

Select the PPPoE radio button. Make sure encapsulation mode is as shown. Click Next.

This step is pretty important. Make sure you enter the correct username and password provided by your ISP(in this case BSNL). Make sure you have ticked Dial on Demand. It means that your modem (which is halfway into being a router) will dial out automatically when you switch it on.

Now for the penultimate step. Enable NAT, and Firewall. A firewall is a system to block unauthorised access. It just makes sure your surfing is safer. Don’t mess around with the service name. Keep it as is, if same as shown below.
dont change service-name

Congrats ! You have configured your Modem to work not only with Linux but also any OS Just click Next then Save and then Save/Reboot.

The only shortcoming you may face, is not having a static IP on your LAN. Here is what you should do, assuming that the modem isn’t shared. Goto Advanced Setup – LAN, and make the following changes.

IP address means the address of the Modem.
Start and End IP address means the range of Addresses that the Server can allocate to connected PCs randomly.To achieve same IP, everytime PC connects to the Modem is to make the Start IP and End IP the same, which means there is only one IP to be allocated.
Or the easier way is Configuring your TCP/IP properties to get the IP address automatically over the LAN.

Remember, if anything goes wrong, no need to pray to God, or send me swear messages, just press the holy RESET button at the back of the Modem !
