If doing this for the first time, setting up a Wi-Fi network can be very tricky. However, sticking to the basics can help to avoid a lot of futility.
Pre-Requisites
There are certain Pre-requisites to connect to Wi-Fi. First you need to check that if your internet is working via LAN. Once, you have a working internet connection, a Beetel 450TC2 modem and a Wi-Fi compatible device like a laptop or a smartphone, you can continue setting up your Wi-Fi network.
In this tutorial, I would like to show you all the ideal settings for most connection types with home and basic ISPs in India, so that you need not worry, if you use a BSNL ADSL or an AirTel WLAN type of network. Just try these steps with confidence.
Steps to Broadcast Wi-Fi
Step 1 — Login to your modem’s administrator section with the help of IP address. First connect your modem to laptop or a PC via LAN cable, open the web-browser and browse for the following address 192.168.1.1 and you will be directed to a login screen or a pop-up asking for credentials.
For stock firmwares, the username is admin and the password is by default password or admin. Please note that these credentials are case-sensitive so type them in small letters only. In case you have changed your credentials before and did not remember them, just find a pin-hole type Reset button at the bottom surface of your modem and press it with the help of a needle, gently for 10 seconds while the modem is on. This restores the factory settings, configurations and credentials.
Step 2. Once logged in, click on Interface Setup and make sure that your settings are the same as shown in the image below. Dynamic IP is highly recommended because it assures seamless yet simple Wi-Fi access.

Step 3. Within Interface Setup tab, there is a sub-tab by the name, Wireless Setup, once again make sure that your credentials are the same as depicted in the image below.
Step 4. Click on ‘YES’ to Broadcast SSID and choose WPA2-PSK type encapsulation method which requires a pre-shared key. In the SSID name field, give a name to your Wi-Fi network like ‘HOME’ and in the pre-shared key, type atleast an 8-digit password that can be numeric or alphanumeric including symbols and special characters. A sample information in given in the image below, then, click on Save.
Step 5. Goto Maintenance tab and restart the modem with current settings. Your modem will now restart and Wi-Fi network will be initialized almost immediately.
