Huawei is a popular brand which supplies modems and routers for many Internet Service Providers(ISP). It is currently the largest company which produce telecoms equipment. The configuration of the Huawei modem varies with different ISPs but we can check whether it is configured properly and connected to the Internet. In case if you cannot access the Internet from a computer which is connected to it, the first step is to ensure if the modem is connected to the Internet. It is not hard to check if you have the login details. To check if it is connected to the Internet, follow the instructions below.

1. Login to Setup Page
   
   Type 192.168.1.1 and type username and password as admin(if you have set different username and password, use that).
   
   
   If you cannot log in to the setup page using the above login IP address, you may want to find the correct login IP address. Many users forget the fact that they changed the default login details in past and try to access the setup page with default login information. To find the correct login IP address of your Huawei router, click the link below.
   How to Find Login IP Address Of a Router
   
   
2. Check The System Information
   
   On the system information page check the IP address of the connection you have made. If you can see a public IP address from your ISP here, Huawei modem is configured correctly and connected to the Internet.
   
   
   If it is connected to ISP and having a valid IP address, then you can ensure the configuration you have made on it is correct. 

In case if it is not getting an IP address from your ISP, you need to reset the device and reconfigure it. We have some tutorials to configure certain Huawei models. I believe these model specific guides will help you better than giving a standard tutorial.

Even if you have configured the modem correctly and getting an IP address from ISP, your computer may face slower connection than expected. There are many reasons for it and you can fix some of them. In this case, if the Huawei modem is getting a slower connection than your ISP promised, I recommend you to follow the instructions provided in the link below.

If you don't want other network computers and devices to find your Windows PC, you can simply do it by turning off Network Discovery on your computer. Network discovery is a Windows feature which lets your PC to see other devices on the LAN and let others see your PC too. If you turn off network discovery on your PC, you will be invisible to other devices on the LAN. The downside is, your computer will also not find any other devices on the LAN. So if you are OK to be invisible to other devices and be ready to don't find other too, proceed further.

To turn off this feature on a laptop with Microsoft OS, you should go to advanced sharing settings. Steps to go there and disable this feature are:

1. Go to Control Panel
   
   
2. View Control Pavel icons by Large icons.
   
   
   Click on Network and Sharing Center
   
   
3. Click on Change advanced sharing settings
   
   
   
4. Check Turn off Network discovery under current profile.
   
   
   You may need to click on chevron to expand the current profile.
   

After selecting the radio button to turn off network-discovery, other devices in the LAN will be prevented from seeing your laptop. This may make file and printer sharing a little difficult between your laptop and another device in the LAN because you are invisible to them. If you do not share anything with other devices, this feature is additional security for you. If you are sharing resources with others, these settings will make you work difficult.

To make your computer visible to other devices connected to the same LAN, follow the steps1 to 3 and then select the checkbox Turn on network discovery. Now onwards there will be no issues for other devices in the same LAN to see you.

We have seen how simple to make a windows computer invisible to other other members in the same LAN. Similarly, it is very easy to enable default user logon picture to all users in a laptop. To learn the trick click on the link below.

If you are a busy type person who does not want to wait for your computer to show the status message of shutdown or log in and logoff, there is a Windows Group Policy tweak to disable them. Once you have disabled the shutdown, login or logoff message from the group policy, Windows will no longer show you the message which reminds users to wait while your computer shutdown or logoff. Let us see how to implement it on your PC.

This Operating system trick is valid only on Windows 2000, 2003 and XP.

You can enable system status message at any time by reversing the Group Policy tweak made on your computer, and you will again see the shutdown status message while your computer is turning off.

To remove the Windows shutdown and logoff status message from your laptop, follow the steps below.

1. Type gpedit.msc on Run or Search and press enter
   
   
2. Click Administrative Templates
   
   
3. Double Click System and double click on Remove Boot/ Shutdown/ Logon/ Logoff status messages(on right pane)
   
   
   
4. Select enable to stop Windows showing shutdown and logoff status message on your computer.
   
   

Go to the Location Administrative Templates> System> Remove Boot/ Shutdown/ Logon/ Logoff status messages and select disable to enable shutdown and logoff status message.

From Windows Group Policy Edit we can change the normal operation of most of the windows features.

In case if you want to disable access to certain tools on Windows for other users, you can set policy in Group Policy Edit.

Or if you want to stop displaying certain messages or alerts on your Windows computer as we have stopped Shutdown and logoff status alert here, you can do the same from Group Policy Edit.

We all know the default size of ping ICMP echo request packet. That is 32 byte. Though the default ping packet size is 32 bytes, we can change it by a simple command while pinging a destination from your computer. By using -l option, you can decide the size of the echo request packets. The valid value of the size of ICMP packets is from 0 to 65500. So the size of the packet should fall in the range.

If you set any value, not in the range of 0-65500, you will get an error with warning bad value for -l, the value range is from 0 to 65500.

If you are facing issues with an MTU value of ICMP packets sent from your computer, changing their size may help you.

Let us check how to change the default packet size of ping echo request.

You need to use the command format provided below.

ping -l (value between 0 to 65500) [Destination Address]


Here let us check how to use this command to change the default size of ICMP echo request packets.

I am going to send packets to a destination address with manually configured value.

Here I use different values, and you can see the result on the screenshot provided below.

Example- ping -l 50 www.corenetworkz.com

Here I have changed the default value of 32 with 50.

Let us check how this command changes the size of echo packets send from your computer.


The above picture shows ping packets send with different sizes.

So I believe you have learned the procedure to assign any size for the ICMP request packets sent from your computer.

Google Chrome is one of the most popular web browsers now. The faster software update is one of the reasons for this success. If you go to the direct download link, you will always get the latest version of the browser. However, by a simple trick, we can download any version of Chrome browser. This tutorial teaches you how to download the older versions of the Chrome browser on your computer.

Let us check how to create a direct download link for the older version of Chrome browser.

We will get an offline installer of it by simply specifying the version number of the required version of Chrome.

We can create a direct download link to it using the last two sessions of the required Chrome version.

The format of the direct download link of any version of the Chrome browser is:

Before using this equation to create a download link for any version, you must check all the available versions.

Without knowing the exact version number, this formula will not give you the download link.

Fortunately, Google publishes a log file of all versions on their blog, and you can find the required version number from there.

To check the available versions of the Chrome browser, visit the link below.

By using the above format, we can create a direct download link for any release of the Google Chrome web browser.

If you find any process running abnormal or not responding, you can kill that process by simply going to the Chrome task manager.

To learn more about this, click on the link below.
How to Kill Not Responding Processes in Google Browser?

While installing a different version, the previously saved Usernames and Passwords stored on your Chrome Browser may get deleted. So, I suggest you take backup of such data before installing a new version.

This tutorial tells the steps to create a direct download link to download and install any version of Google browser on your computer.

While troubleshooting connectivity issues, we may need to change the default TTL value set on the Ping packets. It is because the TTL value (Time To Live) tells the life span of the ping packets. In simple words, it is the number of hops they can cross. When it reaches the hop count set by TTL, it expires. This tutorial explains how to assign a new Time To Live value to a Ping packet and the after effects of this process.

When Should I Assign a New TTL Value
When you ping an address from the Command Prompt, your computer automatically assigns a default Time To Live value (a number greater than the hop count between the destination and your computer).

Sometimes it may not be enough for the packets to reach the address. In those cases, we need to set a different Time To Live value on them.

We can change this value from the command prompt, but the manually configured value must be between 0 to 255.

If the TTL set is 0, ping packets won't go further from your computer. If it is 1, they expire when they reach the subnet.

From the Time To Leave value in ping reply, we can find the hop count between the destination and your computer.

Check the below image to learn how to find the hop count between your computer and different websites.



Here you can see the hop counts between your computer and different addresses.

Use the command below to change the default Time To Live value set on ICMP echo packets.

Ping -i (TTL value) Address

Example: Ping Google.com -i 100

If you set a lower TTL value for ICMP requests than the actual hop count between your computer and destination, they will never reach the address.

The below image shows this.

Here I set a TTL value which is less than the actual hop count between my computer and Google server.

So the packets expired on its way before reaching the destination, and I have received the Time To Live Expired in Transit error message.

1. Ping Request Could not Find Host. Please Check the Name and Try again
2. Error 628: The Connection was Terminated by the Remote computer
3. Error 797: A Connection to the Remote Access Server was not Made

If the Time To Live value set is lower than the actual distance between the destination and your computer, ping packets will expire.

Sometimes you may witness blocked Control Panel (CP) on your computer mostly after a malware attack. Some malicious programs lock this window to prevent you from accessing Control Panel items. Most of the times they use Group Policy or Windows Registry to lock it and it may remain locked even if you remove malware from your computer. This tutorial tells how to unlock disabled Control Panel on your computer with Group Policy and Registry. Even if you are unable to find CP and Control Panel items on the Windows Start menu, from Group Policy we can fix it. You can also use the same instructions to lock it on your computer to prevent others from accessing this feature on your computer. Steps to lock and unlock the control panel on your computer are provided below.

1. Type gpedit.msc on Run (Press [Windows] and [R] to open Run window)
   
   
   
2. On Local Group Policy Editor click on User Configuration
   
   
3. Click on Administrative Template and select Control Panel
   
   
   
4. Double click on "Prohibit Access to the Control Panel" and click on enable to disable it on your laptop. If you select disable, CP will be accessible.
   
   
   
   1. Select Enable if you want to Remove CP From Windows Start menu and prohibit access to it.
   2. Select Disable if you want to unlock the Control Panel and its items on your PC
   
   Do not forget to save settings before closing the window.
   
   
5. Reboot your computer to see the effect

If you select enable radio button users cannot start Control Panel or run any CP items on your PC. Moreover, users will never see it in the start menu. So if anyone is not seeing Control Panel in Windows start menu, you can easily tell them it is being disabled either in Group Policy or in Registry.


Once you have done with unlocking CP from Group Policy, if the issue persists, next you have to look at Registry. Malware can disable Control Panel from there and you must unlock it manually. Before going to change any settings in Registry, I recommend you to take a backup of the current registry by following the steps below.
How to Backup Registry On Your Computer

1. Type regedit on Run and press OK
   
   
   
2. Go to the location
   HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
   
   
3. Select Explorer and right click on the right side to create a new DWORD(32-bit) Value.
   
   
   
4. Change the name to NoControlPanel and double click on it. Now change the value data to 1. Click OK.
   
   
   
   1. If the value data is 1 after reboot CP will be disabled on your computer. You will no longer see Control Panel in Start menu
      
      
   2. If the value data is 0 after reboot Control Panel will be enabled. You will be able to see it in the Windows Start menu

From this tutorial you have learned how to resolve the issue if you are unable to access the Control Panel and its items on your computer using Group Policy and Registry. You have already understood the trick to disable ControlPanel on your computer. Like this, if you want to disable unwanted startup programs on your computer click on the link below.

Two days ago I purchased a new domain name from Godaddy in the same account where I have hosting too. It is very simple to add the domain name to hosting if both features are in the same account. However, I faced a strange issue when I tried to add this new domain name to my web host account. I could not add the name and got an error message this domain is already assigned to an account. For me, it is a brand new name. So I contacted Godaddy technical support.

Technical support team informed me, this domain name already connected to a hosting account in their network. Since it is not my hosting account, someone else added it to his hosting.

I requested the Godaddy team about it. They removed the address from the previously hosted account and informed me to wait 24 hours to add it to my hosting.

I added the domain name to my web host account yesterday. Now it works perfectly.



Now I feel I have purchased an expired domain name which was using Godaddy hosting service. His domain name expired, but the hosting is still active.

If you are facing the same issue this domain is already assigned to an account you can either call Godaddy technical support or use their online support. If you are using online support, (email support) they will respond you back within 3 hours.

If you plan to use Godaddy telephone support, you can use the following phone number to reach them. If you want to use their telephone support, you must use the secret pin you have created while opening the account.

It is to verify that they are serving the real account owner.

I have been using Godaddy services for more than five years. I still remember the days I struggled to add a custom domain for my blogger blog.

I also faced issues with redirecting non-www version of the domain name to www version.

If I type the non-www version of URL to view a blog page, it redirects to the home page.

Do you want to set a software installed on your computer to start automatically when your PC boots up? If you use an application installed on your PC often, it is better to set that application starts automatically. I have a Samsung netbook which I use for browsing. So it makes sense to enable auto start for Google Chrome and Firefox, my favorite browsers. To convert a normal software to start automatically on a computer, we must add it to Windows StartUp.

All the programs and tools listed in StartUp run automatically when the computer boots. This tutorial explains how to enable auto-start on selected applications installed on your laptop.

The second part of this guide explains how to delete a program from StartUp if you no longer want that application start with booting.


Make A Software Runs Automatically
I think it is better to explain this concept with a practical example. I am going to set the Google Chrome to run automatically on Windows boot. You can follow the same procedure to convert any application into an auto-run mode.

1. Open StartUp Folder:
   
   1. Click on Windows Start and Select All programs
      
      
   2. Right click on StartUp and Click open
      
      
      
2. Create Shortcut of Google Chrome
   
   1. Right Click on Google Chrome
      
      
   2. Click on Create Shortcut
      
      
3. Drag the shortcut into the StartUp folder

Now the Google Chrome is added to Windows StartUp. It means, whenever your computer boots, Google Chrome too will start automatically. By following the same steps, you can add any programs on your computer to Windows StartUp and convert them autostarting applications.

Now it is the time to learn about Windows runtime errors. To learn more about runtime error click on the link below.

Remove unwanted Startup Programs
Sometimes you may need to remove certain applications from this list. It is because having so many applications in that folder may reduce your system bootup speed and efficiency.

We can remove any programs from appearing in system bootup menu by removing them from msconfig window.

1. Click on Windows start
   
   
2. On search type msconfig and press enter
   
   
3. Click on the startup tab
   
   
4. Uncheck unwanted programs

The unchecked programs will not appear in that folder again.

Bharat Sanchar Nigam Limited (BSNL) is one of the leading Internet Service Providers in India. Though they provide a preconfigured modem while taking Internet connection, we may need to reset and reconfigure it due to several reasons. If you forgot the username and password set for BSNL modem, you might need to change it to factory default and reconfigure it. Another reason to reset BSNL Gateway is to fix some network connectivity issues. This article is for those who want to reset BSNL modem to factory default settings.

There are two different methods to reset a BSNL modem to factory settings. They are soft and hardware reset. In soft reset, we should log in to the BSNL modem configuration page and select the option to restore default or factory default.

If you do not have the modem username and password, you cannot perform this procedure. It is because without login details you cannot log in to the settings page. In that case, the only option left is to perform a hard reset.

In this tutorial, you will see both methods irrespective of the modem vendor and version.


Soft Reset BSNL Broadband Modem

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

2. Click on the Admin tab
   
   
3. Click on Reboot
   
   
   
4. Select the factory settings and click on reboot
   

Software reset will help you to fix any wrong entries you have made. It can rectify any wrong Internet and wireless settings.

Though this method is helpful, you cannot perform it when you are unable to login to the settings page. In that case, you must go for the second method.
