BSNL Broadband ADSL2+ WiFi Modem Router Configuration Settings

To configure BSNL Broadband you need :-

• Router (DSL,ADSL,ADSL2+) , 
• Splitter (splits voice and data) 
• Cable (RJ45, RJ11)

TP_LINK is the best modem for home users because it has more features in less price (for bsnl users it is great).I personally use it since last two years without any problem with sufficient WiFi Coverage.

here are the complete step for BSNL Broadband ADSL2+ WiFi Modem Router Configuration Settings :-

1. from web browser type 192.168.1.1
2. enter username "admin" password "admin" and click login.(its a default username and password,you can change it later)
3. wait for line status from "initializing" to "connected" (once connected,you can see current rates,max rates,SNR margin,Line Attenuation,Errors for upstream and downstream)
4. now click on "Quick setup"
5. enter VPI (Virtual Path Identifier) = 0 and VCI (Virtual Channel Identifier) = 32
6. select PPPoE (Point to Point Protocol over Ethernet)
7. enter username and password that your service provider has given you. (by default it's usually in the format of your surname's first two letter area code (without zero) your land line number_ bsnl division) example :-  if your surname is Sharma ,your area code 021,your number 2295434 and division is western India i.e wcdr  then your username sh212295434_wcdr and password is by default "password"
8. now setup WiFi  

• wireless network name (you can choose any) 
• region (select India ) 
• channel (auto or select if you are in WiFi crowded area select channel 1,6 or 11) 
• mode (11bgn mixed or 11bg mixed) 
• security (select WPA-PSK/WPA2-PSK (Recommended)) and set your WiFi password then click next you will see your connection status (all should be showing status successfully)
• you can also configure WiFi by clicking wireless on left side of the router login page

      9. now from laptop or mobile turn on WiFi,select your WiFi name and enter password.you                       successfully configure your ADSL2+ router modem

How to Setup Cisco IOU on GNS3 ?

By using CISCO IOU on GNS3 to emulate Cisco Layer 2,Layer 3 switches and router for better Performance rather than using Dynamips.you can add 100+ Device without affecting memory utilization.

What is CISCO IOU ?

Cisco has developed special ios that runs on UNIX/Linux called as CISCO IOU.
IOU means Ios On Unix which is used by Cisco internally for research and testing purpose.

Who can use it ?

Cisco Learners & certification exam takers for lab exercise practice
for Network Engineers,Network Administrators or Networking professional to check and test their Projects/Networks

How to implement it on GNS3 ?

there are two ways to emulates Cisco ios:-

1.by using Dynamips which utilize more memory so we can add limited number of devices.also you can enable switch functionality by adding ESM module (Ether Switch Module)

2.and other is IOU by using visualization by using it you can add more and more number of devices(router and switch) and emulate switch ios on it with more supported commands(90%).(not to worry about APIC Hardware)

What is the Advantage of it ?

you can run more Virtual device (Virtual routers and Virtual Switches)
100+ simultaneously on a PC computer or laptop running Linux (use virtual machine to run Linux on windows or any OS).
you can implement entire Enterprise network on your computer PC.
