Wireless ADSL Router for Reliance Broadband (Wireline Internet)

UPDATE:
The below said procedure also works with other TP-Link Modems, Wireless router with modem and other brands if they support connection to Internet via Dynamic IP (as seen in Step 13 in the post below).
Personally i suggest checking the compatibility of the modem by browsing through the website of the Wireless Router Manufacturer.
For TP-Link they provide emulators of the most of their devices at

Hi Friends (its also for new people visiting this blog, new friends :) ),
A new post after a very long time,
This post is for people who is into hunt for instructions on using a wireless router with built-in ADSL Modem into it, otherwise called Wireless ADSL Router.


This is for people:

• Using Reliance Wireless Broadband Internet Connection.
• Using the login screen below to access the internet.

 

  

• Using the ADSL modem provided by the ISP, but wanted to have a wifi.
• Who is having separate ADSL modem and a Wireless Router, but wanted to have a single device for both.
• Having a wifi enable device or devices, laptop, tablet PC, smartphone; and wanted to use the broadband on all them simultaneously.

I too had the same problem, but wanted to move on to a what called "single device" modem cum wifi router.
But when asked with the ISP Customer Care, they didn't provide enough information on switching to other devices than the one that is provided.

When after spending so much time on the internet hours together, with no resolution.

Having some enough knowledge on those router, i gave a try with Dlink DSL-2750U, it didn't connect.
Then tried with iBall Baton iB-LR6111A ADSL2+ Router, it did connect, but not in such a way to share it.

But, once found a person telling that he is using a device as such. It was TP-Link TD-W8951ND

With that information, i made a study on it, it's quite a good router, but doesn't meet my needs, so i planned for a little bit higher version.
I then found on TP-Link website that TP-Link TD-W8968
was a higher version of the above stated router, so i went for it and bought it.

The setup for Reliance Broadband on that router was so easy, i didn't had to break my head for it.
It took only around 2 minutes to setup the internet and i was so happy to see that i got connected to the internet :)

Let me tell the procedure to setup TP-Link TD-W8968 (also applies to similar models of TP-Link) for Reliance Broadband (Wireline Internet).

Important: Before using these devices, make sure that you logged off from the portal.
1. If it is a brand new router, connect the power, telephone line and the LAN cable to the router.
(If it has already been used, make sure you reset to the factory default settings).

2. Note down the IP address or URL, the username and password, in a paper or text editor, which is found on the bottom side of the router.
3. You can now place the router on the table in the normal position.
4. On your PC or laptop, make sure the Ethernet card or NIC settings are set to automatically obtain IP address.
5. Connect the other end of the LAN cable to your Laptop or PC.
6. Power on the router.
7. Wait for a few seconds for the router to boot up and assign an IP address for your connected system.
8. Open your favorite Web browser.
7. Enter the IP address or the URL that you have noted down in the URL bar.
(In my case, it is http://192.168.1.1)
8. A dialog box will pop up asking for the user credentials, you can enter the username and the password that was noted down earlier.
(In my case, username: admin ; password: admin)
9. After successful login, you will be shown the status page of the router. If you were unable to access this page, you are requested to verify with the details under the router, or with the router manual.
There are some default user credentials, you are also requested to try these.
username: admin
password: admin

username: admin
password: password

username: admin
password: <blank>

If still you were unable to access the page, you are requested to reset your router using the reset button, to know more on how to use the reset button on your router, please refer the user manual of the router.

10. In the main page, you will be provided with model number and the firmware version of the router

11. On the left hand side, there will be a pane with several option for setting the router.
12. You need to select, Network -> WAN Settings.

13. On selecting the above option, you will be provided with main screen as below:

You need to enter the following in the corresponding boxes
Under ATM Configuration
VPI: 0
VCI: 35
Under WAN Service Setup
Connection Type: Dynamic IP
Enable IPv4: Tick
Then click on the Save button below.
14. On saving this you will be taken to screen which shows your connection as below, waiting for a few seconds, you will be assigned an IP address by your ISP. And you will get the Connected Status.

For some security reasons, i had to hide the IP assigned to me.

Thats all for the internet,
The remaining setup of the wifi and password protecting your wifi part is left to you, as it is an easy thing to do.

Happy Browsing through the wifi and using all the wifi enabled devices simultaneously.

Amazon EC2 Cloud Computing Used To Hack Wireless Network Passwords

German security researcher Thomas Roth has found an innovative use for cloud computing: cracking wireless networks that rely on pre-shared key passphrases, such as those found in homes and smaller businesses. Roth has created a program that runs on the Amazon Elastic Cloud Computing (EC2) system.

It uses the massive computing power of EC2 to run through 400,000 possible passwords per second, a staggering amount, hitherto unheard of outside supercomputing circles -- and very likely made possible because EC2 now allows graphics processing units (GPUs) to be used for computational tasks. Among other things, these are particularly suited to password cracking tasks.

In other words, this isn't a clever or elegant hack, and it doesn't rely on a flaw in wireless networking technology. Roth's software merely generates millions of passphrases, encrypts them, and sees if they allow access to the network. However, employing the theoretically infinite resources of cloud computing to brute force a password is the clever part.

Purchasing the computers to run such a crack would cost tens of thousands of dollars, but Roth claims that a typical wireless password can be guessed by EC2 and his software in about six minutes. He proved this by hacking networks in the area where he lives. The type of EC2 computers used in the attack costs 28 cents per minute, so US$ 1.68 is all it could take to lay open a wireless network.

Roth intends to make his software publicly available, and will soon present his research to the Black Hat conference in Washington, D.C. Using EC2 for such ends would be against Amazon's terms of use, of course, but Reuters quotes Amazon spokesman Drew Herdener as saying that if Roth's tool is used merely for testing purposes, everything's above board.

Roth's intention is to show that wireless computing that relies on the pre-shared key (WPA-PSK) system for protection is fundamentally insecure. The WPA-PSK system is typically used by home users and smaller businesses, which lack the resources to invest in the more secure but complicated 802.1X authentication server system.

WPA-PSK relies on administrators setting a passphrase of up to 63 characters (or 64 hexadecimal digits). Anybody with the passphrase can gain access to the network. The passphrase can include most ASCII characters, including spaces. WPA-PSK is believed to be secure because the computing power needed to run through all the possibilities of passphrases is huge. Roth's conclusion is that cloud computing means that kind of computing power exists right now, at least for weak passwords, and is not even prohibitively inexpensive.

So if your network relies on WPA-PSK, its time to check that passphrase. It's claimed that up to 20 characters are enough to create an uncrackable passphrase, but the more characters you can include in the passphrase, the stronger it will be. It should be noted that Roth very probably cracked open networks with short passwords.

Include a good variety of symbols, letters and numbers in the passphrase, and change it regularly -- monthly, if not weekly. Don't use words you might find in a dictionary, or any words that are constructed cunningly by replacing letters with numbers (that is, passwords like "n1c3"); hackers are way ahead of you on such "substitution" tricks. Passphrases constructed like this are effectively impossible for computers to guess by brute force, even by cloud computing systems running Roth's software, due to the amount of time it would take.

Because WPA-PSK is also calculated using the service set identifier (SSID, or base station name) of the wireless router, it also makes sense to personalize this and ensure it isn't using the default setting (usually the manufacturer's name). This will protect you against so-called "rainbow" attacks, which rely on a look-up table of common SSIDs.
