How to Perform Port Forwarding in BSNL Modem

Updated on March 08, 2012

BSNL supplies modem with default firewall which prevents traffic through uncommon ports to ensure the security of devices connected to it. Sometimes it can be annoying because certain applications need some of these ports to work properly and the firewall settings prevent these applications from running properly. Port forwarding requires to fix issues with playing online games, online conferences or messaging, establishing a VPN connection through the BSNL modem. If you have installed an online camera on your network, you may need to open certain ports to it access through the Internet. Port forwarding for certain applications are already defined on BSNL modem and all you have to do is just enable them. For other applications, you should make sure you have the correct port number and the protocol type (UDP/ TCP) before starting the process. You can get this number either from the specific product manual or from their technical support.

Error 777 :The Connection Attempt failed due to Remote Computer Out of Order

Updated on June 29, 2011

For the last few weeks, I have been getting an error message "Error 777: The Connection attempt failed because the modem (or other connecting devices) on the remote computer is out of order" while connecting to the Internet. I use Huawei Access Manager to connect to the Internet because the modem provided by Tata Photon Plus is from Huawei. Mainly the issue occurs in the evening (that means the peak time) and the error message prompt me to either redial to connect to the Internet or cancel. Here I would like to share the major reasons of "Error 777: The Connection attempt failed" and its possible solutions. After a few attempts, I would be able to go online but in some worse cases, I waited hours to get rid of the error.

If you are not sure how this error message looks like, have a look at the screenshot provided below.

Reasons for Error 777: The Connection Attempt failed

The possible reasons for "Error 777: The Connection attempt failed because the modem (or other connecting devices) on the remote computer is out of order" are:

Usage of the incorrect driver for your modem
The number dialed by your modem is blacklisted
Outdated modem driver

In addition to the above-mentioned reasons, I am getting this error message only in peak time. So I assume, the network users can also be a factor but I am not sure.

The Solution for Error 777: The Connection Attempt failed

The major reason for "Error 777: The Connection attempt failed because the modem (or other connecting device) on the remote computer is out of order" is faulty modem driver.

Unplug the modem and reconnect (If you are using a USB modem or external modem )
Restart your computer
Update the driver
Uninstall the current modem and reinstall it with the latest driver available.

Activate Disabled WiFi On BSNL Wireless Modem

Updated on September 03, 2010

BSNL is the leading Internet Service Provider in India. They offer wireless modem with routing capability for their users. Since the modem has DHCP server, users can connect multiple computers to it both by using Ethernet cable and WiFi. This tutorial explains how to manage BSNL WiFi by tweaking it. Issues like disabled WiFi and weak network security are addressed in this guide. It also explains the steps required to enable disabled WiFi functionality on a BSNL modem and strengthen the protection by preventing unauthorized people from accessing it.

Steps to Manage Wireless in BSNL Wireless Modem

Login

Type 192.168.1.1 on the address bar of your browser and press enter.

Now you need to enter the user name and password set for your BSNL modem. By default it is:

Username: admin
Password: admin
Click on Configuration
Click on Wireless Network

Here you can manage basic settings of WiFi. You can either turn off or turn it on from this page by selecting the right button. If you want to change the WiFi name, all you have to do is to delete the current entry at SSID and type the desired name.

Procedure to Configure BSNL Wireless
Prevent Unauthorized Users

By default BSNL WiFi is unsecured and anyone can join it and share the broadband connection without your knowledge. You can prevent this by enabling protection. BSNL supports WPA and WEP. You can choose the suitable one from the list below. Do not forget to take note of the key generated because now onwards, you cannot join the network without entering the key.

Filter Based On MAC Address

If MAC address filtering is activated on BSNL Modem, users will find issues with joining Wireless network even though they have the right username and password if MAC address of their devices is not in the white list. If anyone face issues with connecting to your network, you must go to the setup page and check under MAC filtering. Here you check the status of MAC filtering. If MAC filtering is activated, you must turn off it to resolve the issues with accessing BSNL WiFi network. It is important to note that BSNL modem supports two types of filtering, white list, and blacklist. If you have added a particular computer under blacklist, that computer will not be able to access the network. If you have enabled white list, only computers which are under white list are allowed to join the BSNl wireless network.

Wireless Channel

Another point we must check while facing connectivity issues is to change the current Wireless Channel. We can use channel 1, 6 and 11 for the best connectivity. If you are using channel 1, I recommend you to try channel 6 or 11.

How to Check My Tata Photon Plus Internet Usage and Bills

Updated on January 25, 2010

I have been using Tata Photon Plus service for one month while my roommate is using Reliance Netconnect for his Laptop. We have chosen different wireless broadband services for our laptops because of the concept "Don't put all your eggs in one basket". I purchased my Tata Photon Plus wireless USB modem from their online store instead of the local dealer. It is because there was an offer (Laptop bag worth of 1.5K ) for every online Photon Plus purchase.

Update: Special offers are purely up to the time to time decisions made by Photon plus marketing team and I am not sure they offer the same at this point in time.

I received the packet including Photon plus modem (with a small delay) and the Internet is working fine (Though I am not getting 3.1Mbps what they offered) with reasonable speed. Seems everything fine but now only I noticed one issue how to check my Internet usage ?. In the manuals I received, it is written that you can check the Photon Plus Internet usage by login to online Photon Plus account but I didn't receive any online account details. Then I followed the online instructions and found that we need to create an account first using our connection number and tata photon plus account number instead of a ready-made account usually provided by ISPs.

Then the second problem... I don't know what is my account number and connection number. The local Tata photon plus agents activated the device on my computer and went without giving any clues. Somehow I found the Photon Plus account number by checking the mails (e-bill) and find the connection number via photon plus customer support. Now only I understood I am in time-based plan instead of data based plan. Right now I send a request to tata photon plus customer support to change the plan and waiting for their response.

Update: Successfully changed to data based plan (Took just one day only).

Compare Tata Photon Plus With Other Mobile Broadband Services

I think if you are not yet started using Photon Plus service, you may be wondering to have a comparison between other wireless broadband services. Let me tell you frankly the speed and reliability of any mobile broadband service depends on the signal quality at the user location. So it may not be true if I say Photon plus is faster than BSNL Wireless broadband (WiMAX )or vice versa. It purely depends on how good the signal quality of WiMAX service and Photon Plus service. So my recommendation is to tell the service provider to show a live demo of the Internet speed at your location before taking the final decision. Nowadays you can see a lot of advertisements about the unlimited Internet Usage Plans by Photon Plus and Other service providers. Before biting the ads it is your duty to read carefully the conditions to use unlimited usage plans. You may not expect the same speed after crossing the threshold (for example 3GB download) and after crossing the threshold download value, your service may be degraded to 2G automatically. I think it will be helpful for you if I leave links to my articles about other major wireless broadband service providers.

Photon Plus and Reliance Netconnect:

If you are looking for a comparison of Tata Photon plus service and Reliance Netconnect, I suggest you read my article about the later by following the link below.
Reliance Netconnect Wireless Broadband Service
Photon Plus and Idea Net Setter:

Just like Photon plus service, another market leader in wireless broadband service is Idea Net Setter. Though Photon Plus use CDMA, Idea Net Setter is 3G (GSM). To learn the speed difference between Photon Plus and Idea 3G at your location, better you can go to their official sites or ask the representatives to give a live demo. To read about Idea 3G broadband, click on the link below.
How to Configure Idea 3G Broadband On your Handset
Photon Plus and BSNL WiMAX (3G EVDO):

Just like Photon Plus by Tata, BSNL also has 3G broadband service. One of the differences between BSNL EVDO service and Photon Plus is the difference in technology. Photon Plus use HSIA while BSNL uses "Evolution-Data Optimized". To learn about BSNL 3G follow the link below.

Purchased Samsung N128 Mini Laptop

Updated on December 30, 2009

Published By Alex George

I purchased a Netbook from Samsung(Samsung N128) two weeks ago, and I think it is time to write a review of it.

It is travel-friendly because of its small size, and nowadays I need to travel a lot. While on a journey, it is difficult to carry my laptop because of its size. So, I planned to go for a mini laptop.

I found many products that suit my travel needs.

After checking different brands, I decided to buy Samsung N 128. You must be interested in knowing my experience with it.

Let me share my review of the Samsung N 128 netbook with you. So, you can find out if this product is suitable for you. The below picture shows what it looks like.

We are having trouble playing this video right now. Please try again or select another content.

How does it look? Fine right? Now, we check the system configuration.

Samsung N 128 Mini Laptop Configuration

Processor	Intel ATOM 1.6 GHz Processor ( ID: N270)
RAM	1 GB DDR-2 Ram
Hard disk	160 GB HDD
Monitor	10.1" Wide LED Screen (Extra bright)

Other Features

Father Ethernet port
Webcam
WiFi

Ports

Available Ports and connectors on the Samsung N 128 Mini Laptop are:

3 USB 2.0 ports,
VGA out,
DC power-in,
RJ-45/Ethernet (10/100),
Stereo headphone/line out,
Stereo microphone in,
VGA webcam,
Kensington lock port.

The total weight of this netbook is around 1.25 kg, and it has a 6-cell battery. This product comes with a one-year warranty. I bought a non-OS installed version and installed Windows 7 and Ubuntu. It supports both operating systems perfectly well.

Samsung N128 Mini Laptop Review

It is working better than I expected. At first, I failed to find a WiFi adapter driver compatible with Windows 7. The setup disc has only the Windows XP version of the Wireless adapter driver.

I downloaded the latest version of the wireless adapter driver from the manufacturer's website. I must say, the speaker volume is lower than I expected. It has a 1.5-watt speaker. The volume is low, and I need a headset to hear the sound properly. The next point I want to point out is about battery backup.

The shop owner promised me an 8-hour battery backup, but when I checked, it was just 6 hours only. Besides this speaker volume issue, I am satisfied with the Samsung N 128 netbook.

Detect If Your Yahoo Messenger Chat Contact in Invisible Mode or Offline

Updated on June 29, 2009

Published By Alex George

Yahoo Messenger was once one of the most popular online chat platforms. Although Yahoo discontinued its public chat room feature, many users continued to use it.

In this article, I will discuss several tools that could determine the status of Yahoo Messenger contacts.

I will teach you to find whether they were online, offline, or in invisible mode.

How Do I Detect an Invisible Yahoo User?

Julia Sebastian, a regular reader of CoreNetworkz Tech Solutions, asked, "Hello Alex, is there any trick to find an invisible Yahoo user?"

The answer is yes.

When a user chooses invisible mode, Yahoo Messenger displays her as offline. However, specialized "invisible detector" tools could identify whether a contact was truly offline or appearing that way.

These tools helped users figure out if a contact was intentionally avoiding conversation.

Hannah Maria, a reporter at CoreNetworkZ Tech Solutions, told me, "I use these Yahoo status checker tools to find whether a person blocked me on Yahoo."

Hannah is right.

For instance, if a contact appeared offline in your messenger but one of these tools detects her as online, the person had likely blocked you.

Free Yahoo Invisible Status Checkers

Let me share some of my favorite tools for checking Yahoo user's online status. They are ydetector.com, imvisible.info, detectinvisible.com, who-is-invisible.co.cc, and ybuddy.info.

These platforms allowed users to check whether a Yahoo Chat contact was using invisible mode.

Yahoo Messenger Invisible Detector (YDetector) – Check YM User Status

YDetector is a free online tool that checks the status of a Yahoo Messenger (YM) user ID. If a contact is in invisible mode, the tool can detect and indicate that the user is not offline.

Below is a screenshot demonstrating how the tool displays a status of 'offline' when a user is signed off.

If the user is truly signed out, the status will appear as Offline. Similarly, the tool can detect if a contact is 'Available' or in Busy mode.

Check the Status of a YM User with Imvisible

Imvisible is another free and widely used web-based tool that allows you to check the real-time status of any YM user ID. Like YDetector, it identifies whether a user is online, offline, or hidden in invisible mode.

Detect Yahoo Messenger Status with DetectInvisible

DetectInvisible is another effective tool for verifying a Yahoo Messenger contact's status. It not only displays whether the user is online, offline, or invisible but also allows users to save the avatar of the checked Yahoo contact.

Below is a screenshot example showing a user detected as Online.

William Brown, a client of CoreNetworkz Tech Solutions, mentioned, "It is helpful to determine whether a Yahoo Messenger contact is genuinely offline or simply using invisible mode."

I agree with William.

Some users might appear hidden because they are genuinely busy and unable to chat—while others may have chosen to block you from viewing their real status.

By analyzing the results returned by these detection tools, you can often infer whether a friend has deliberately hidden their availability or potentially blocked you altogether.

I recall your attention to what Hanna told me. She uses these tools to determine if a Yahoo user blocked her.

In addition to the tools previously mentioned, many other free utilities can help check the real-time status of Yahoo Messenger contacts. Some of these include:

Local Area Network (LAN) - CCNA Study Material

Updated on June 07, 2006

Welcome to the Network Engineer Training Tutorials by CoreNetworkZ Tech Solutions. Today, I will be discussing Local Area Networks (LANs).

Let me start this tutorial by explaining the LAN.

A Local Area Network (LAN) is a collection of connected devices within a small area. A home network (with one router connected to computers and smartphones) is an example of a LAN.

Ethernet is the most popular LAN technology today.

A LAN facilitates communication between devices in a small area and improves work efficiency in an office environment.

Which Network Is a LAN?

Sharon Joe, a CCNA student, asked, "What type of network belongs to the category of a LAN?"

Questions about LAN technologies are in the CCNA and Juniper JNCIA-Junos examinations.

Let me now answer Sharon's question here.

So, how do we determine if a network is a LAN? In a LAN, all devices are connected and can share data. It typically covers a small area, such as an office building or home.

The media types used to connect devices in a Local Area Network (LAN) include Ethernet, FDDI, and Token Ring.

CCNA Questions From LAN Topologies

Let us now consider the common topologies used in Local Area Networks, as this topic is part of the CCNA exam syllabus.

Laxmi Vinod, a B.Tech (Computer Science) student from Chennai, asked, "Can you explain the concept of LAN topologies?"

CoreNetworkZ Tech Solutions classifies topology into two types: physical and logical.

Physical topology refers to the actual layout of devices in a LAN, while logical topology describes how these devices communicate over the network.

LAN Physical Topologies

Point to Point

If we connect two devices without interference from other devices, that is a Point-To-Point physical topology. In this LAN topology, these two devices can communicate without extra support.

Wireless Bridge is an example of Wireless Point-to-Point Topology.
Bus Topology
You can say it is an extension of Point-to-Point topology. In Bus topology, we connect all devices in LAN in a single connection.

Ethernet uses Bus topology.
Ring

If a Local Area Network has Ring Topology, all devices are in a ring form. It means PC 1 connects to PC 2. PC 2 connects to PC 3, and the last device connects to PC 1. So, it forms a ring structure.

FDDI uses a ring topology.
Star Topology

In start topology, all devices in a LAN have a connection to the central device. An example is all the computers connected to a Switch.

LAN Logical Topologies

Bus Topology

Ethernet is an example of a LAN technology using a logical bus structure to communicate. To learn more about Ethernet, visit the link below.

Fundamentals of Ethernet
Ring Topology
Token Ring is a good example that uses ring logical topology to communicate computers connected to the network.

The medium of Transmission in LAN

I will complete today's article by explaining the last question asked by a reader on CoreNetworkZ Tech Solutions.

Sanal Mohan, a working professional from Bengaluru, asked, "I am planning for a career change. I am about to join a course on Juniper and Cisco products. So that I can become a Network Engineer. My question is about the medium of transmission in local networks."

Here is the list of media of transmission as an answer to his question.

Twisted-pair wire
Coaxial cables
Fiber optic cables
