How to Change ISP DNS Settings On Linksys WRT54G Wireless Router

DNS (Domain Name System) Server resolves domain name you type on the browser address bar into respective IP address. While configuring a Linksys router, it takes the default DNS server information provided by your Internet Service Provider. It usually works fine but if your ISP owned DNS server is slow, you can edit the Domain Name System entry set on Linksys router by yourself and change it with better server details  you want to enter. This tutorial explains how to change the current DNS settings on Linksys WRT54G wireless router.

Change Current DNS Details On Linksys WRT54G Router

Redirect Namecheap Non-WWW Domain to WWW Version Blogger Custom Domain Address

Today I have added a custom domain name ( purchased from Namecheap for my blogspot blog ( I have successfully completed the steps to set custom domain name in blogger account and everything seems fine. Google successfully redirects blogspot address to custom domain name. Though everything looks fine, I am not able to access my blog using the non-WWW version of the domain name. Whenever I type naked domain, it doesn't show my blog but with WWW version, it works fine. There is some kind of redirection issues either with blogspot or with Namecheape. I must say, I couldn't find enough tutorials to solve this issue and I had to spent a lot of time to identify and rectify the problem. This tutorial explains how to do correct 301 redirection from naked domain to WWW version.

301 Redirection Of Naked NameCheap Domain to WWW Version
  1. Login to namecheap account

    Click on to access their website and Sign In using the username and password you have created.

  2. In My Account page Click on Manage domains or you can click on view link near number of domains in your account.

  3. Click on the domain name which shows redirection problems

  4. Click on URL Forwarding under Host Management

    Here we must enter the CNAME details (Alias), Type of URL redirect (301 redirection), DNS details insertions etc.

  5. Enter the following details

    Under IP Address/URL, @ is http://www.your and www is If you are prompted to enter a manual TTL value, it is 1800. The URL Redirect should be 301 and select CNAME (Alias) as below.

    After entering the details, click on Save Changes.

  6. If your site is hosted with blogger, I recommend you to follow the instructions provided in the link below.
    Complete Blogger Custom URL Configuration

Now if you type your blog address without WWW (naked version of the custom web address), it will be directed to the WWW version of custom domain. Redirecting non-WWW version of blog address to WWW version helps to retain visitors who use the naked address of your website. So you will not loose your visitors who are not using WWW prefix. 301 redirection ensures the permanent redirection of nonWWW version of your URL to WWW version and avoid duplicate content issues in Google.

Now visitors using naked and WWW version of blog address will reach your blog without having any redirection issues. Since any changes with CNAME details may take time to show, you may need to wait a few more hours. If the issue persists even after waiting for more than five hours (though recommended to wait 12 hours), I suggest you to cross check the settings you have made in NameCheap account and rectify any deviations.

First step is to enter CNAME and a-records in domain (registrar website) control panel and second step is to enter the new address which you want to point to your blogspot blog.

1. How to Enter CNAME and A-Records For Your Blogger Blog

Before set domain name pointing to your blogger site from blogger account, you must enter the CNAME and A-records in the domain registrar's control panel.To do this step, you must log on to registrar's website. Under domain management, you can find DNS (Domain Name System) settings. In that page, you can enter following information. For more information, I recommend you to refer the steps mentioned in the link below.
Redirect Naked Namecheap URL to WWW Version

A-records should point following 4 IP addresses.

It may take hours to activate the DNS settings you entered in registrars website. After this you should make following changes in blogger account.

  2. Post wise redirection:

    Each blog posts will be redirected to the respective new URLs.

  3. It is easy to promote a custom name rather than .blogspot address

Last point is also very important as first two points because .blogspot or WordPress addresses are difficult to promote and look unprofessional. There is not much financial troubles associated with buying a new domain name because all you have to spent is around $10 per year as the registration fee. I bet, any serious blogger can earn more than $10 per year from AdSense through this site. I have been blogging since my college days but after two years from the starting day only I recognized the importance of having a domain name. Once I bought the address, I understood its importance. It gave a professional touch and gradually helped me to increase the visitors count. One advantage of starting with blogspot is the facility to use custom name even if you are hosting your site in their server. So you can avoid the expenses of buying a server space. Definitely a custom domain name can make your blog promotion easier. To learn about the promotion, click on the link below.

Computer is Online with USB Cable but Cannot with Modem LAN Port

Today I received a call from one of my friends to discuss a strange network issue. He can access Internet on his computer using USB cable connected to his modem but it is not working when he tried to use Ethernet cable to connect his computer to the modem. His modem has router feature with 4 LAN ports and he decided to use them to connect his second computer. So he removed the USB connection and connected his computer to the LAN port with Ethernet cable. However, his computer failed to access Internet and he has no clue. This tutorial explains how to deal with such a situation and I tried my best to make it easy to understand and follow.

Online With uSB Port But Not With LAN Port

In case if you have troubles to go online when connecting your computer to the LAN port (Ethernet Port) but can go online with USB port of the modem, follow the procedure below.

  1. Check the LED on your modem And at Computer LAN Port

    If there is no light on your modem (LED near the LAN Port) or at Ethernet port on computer, it shows no active connection between your computer and modem. Possible reasons can be;

    • Loose connection- Unplug the cable from both ends and connect back
    • Modem LAN Port issue - connect cable to another LAN Port
    • Faulty Ethernet Cable - Try a different cable
    • Faulty Computer LAN card

  2. Check Computer IP Address

    If Static IP address is assigned to your computer, you must use obtain an IP address automatically option. It is because if your computer static IP address does not match the network address of the modem DHCP, your computer will not go online.

  3. Power cycle the modem

    In this step you need to disconnect power cable from the modem and wait for 1 minute. After one minute power on the modem and wait still all the lights are steady.

  5. Disable Firewall and check for the issue

    It is advised to disable the firewall protection on your computer and check for the issue.

  6. Connect your computer to another modem

    To rectify the issues with the LAN port of your computer/LAN port of your modem
    either connect a different computer or Laptop to the modem, or connect your computer to another modem.

Last step isolates the culprit port. If the issue is with modem port, you need to contact your ISP. If your computer LAN port is defective, contact your hardware vendor.

Steps to add Open DNS in Ubuntu Linux

Today I faced some DNS issues with my new computer after installing Ubuntu in it. After some basic troubleshooting steps I assigned Open DNS address to my network adapter and the issue is resolved. Open DNS is a smart way to make our browsing fast and reliable. As the name suggests this DNS service is absolutely free and worth a try. Before go to open DNS we need to know a little bit about DNS. As we know DNS is used to convert the domain name of of website to its IP address. For any communication your computer should know the mac address and IP address of the destination (Here web server). MAC address can be obtained from ARP table and if the user type the IP address of the web server computer knows both. If the user type the domain name of the website your computer don't know the IP address of the destination and the communication will not happen. Here the DNS server helps. DNS helps to resolve the domain name to IP convertion issue and send the destination IP address to the computer.

So it is understood that every computer which connects to the Internet should know the DNS server address. There are many DNS servers available including your ISP's DNS server. Here I am presenting the steps to assign Open DNS in Ubuntu linux.

How to Disable or Enable USB Ports from Registry & BIOS On a Computer

USB (Universal Serial Bus) is one of the important method to send or receive information from a computer. In order to improve the safety of information stored on a PC, it is good to disable Universal Serial Bus for unauthorized users and it is a simple task if you have admin rights. In this tutorial I would like to share one method to disable and enable them on a PC from registry. Since registry editing is a sensitive task, I would like you to follow the steps carefully and strongly recommend you to take a registry backup before proceeding. If you are not the only admin of your computer, I recommend you to follow the BIOS method to block Universal Serial Bus on your computer. Steps to block them from BIOS are listed at the end of this tutorial.

Check Frequency of RAM Module On Your PC With Specifications

While counting the performance of a personal computer, Random Access Memory (RAM) has very important place. It helps to improve the data transfer rate between hard disk and processor by acting as a buffer. Major portions of processes and files required for a software while running on a computer are stored in it and provides them when ever processor asks for it. So it reduces the time taken to fetch data from slower hard disk to processor while running a program. Speed of Random Access Memory depends on frequency and memory size. This guide explains how to check the frequency of a RAM module installed in a PC.

How to Check the speed/Frequency of RAM

If you do not know the speed of RAM module installed on your PC, you can find it by any one of the methods given below.
  • From the label

  • From BIOS

First place I recommend you to look for this information is the label attached on it. You will get most of the necessary information like RAM manufacturer, frequency etc. If you are unable to get information from the label, you can get the details from the BIOS. To log on to BIOS press [F2] or [Del] { Depends on the computer manufacturers, the key to enter BIOS may change} while booting your computer. On the main page of BIOS itself you can get the Random Access Memory details like the slot where it is inserted, Size of the module, Frequency /Speed etc. To get all information related to the RAM module inserted on your laptop from BIOS settings, follow the steps below.

  1. Reboot your laptop

  2. Press [F2] or [Del] as told in the motherboard manual

  3. Enter BIOS

  4. Get the necessary details from the main page itself

Different Types of RAM Modules
  1. SD

  2. DDR1

  3. DDR2

  4. DDR3

Points to Remember While Buying Random Access Memory Modules

  1. Certain motherboards do not recognize certain RAM modules. So check the compatibility before buying it

  2. If you want to add extra module to your PC, make sure the new Random Accessory Memory module has same frequency of the existing module.

  3. After all it is important to know the warranty period of RAM. Some vendors offer one year warranty while others offer three year. It is better go with products offer higher warranty period.

My Laptop is Not Getting Wireless Signals and Internet

Today one of my clients called me while I was waiting online for him. He informed he couldn't come online because there is some issues with WiFi connection. He was sitting at a Hotspot but his Laptop failed to get wireless signals and mot online. He knows I am a network engineer and asked me to help him to resolve the issue. It was not a big issue and I fixed that without taking much time. Then I realized, for a non technology person, even smaller issues can be big and ruin his day. So I would like to share some tips to troubleshoot your laptop if you are facing troubles with getting signals or Internet connectivity.

No WiFi or Internet On Laptop

You do not need to go for assistance from expert or hardware vendor in case if your laptop stops receiving  signal. You may just go through the guide below and I am sure in 99 percent cases you can fix it by yourself.
  1. Wireless Button should be turned on

    Make sure wireless button on your Laptop is turned on. If it is off, your laptop will not receive signal from Access Point. The wireless button can be present on the top or side panel based on the models. For different vendors like Dell, Toshiba, Samsung etc. WiFi button might be placed on different location. It can be distinguished with the WiFi symbol. For more details I recommend you to refer the user manual of the Laptop.

  2. Make sure WZC is started

    Wireless Zero Configuration (WZC) is a service which is essential to receive wireless signals on your computer. To know how to check the status of WZC and how to turn on click on the link below.
    How to start WZC on your Computer

    WZC is on Windows XP but for higher versions you must check for Wlan AutoConfig in services page. To get instructions to start this service, I recommend you to go through the link below.
    How to Start WLAN AutoConfig

  3. Clear All Previous Network Details

    You may clear the previously saved network lists from your PC and refresh the network. Your computer may start receiving signals from Access Point. to learn more about it I recommend you to click the link below.

  4. If the issue persists even after performing the steps provided in the above link, you need to disable the Firewall on your Laptop. After disabling the firewall check for the issue. Even if you are not able to detect any wireless signals I suggest you to follow the steps provided in the given link.
    I am not getting WiFi even after I disabled the Firewall

Some users may find issues with following step 2 because vendor provided wireless utilities might be running on their computers. For example, Dell WiFi utility. Sometimes this tool acts strange and shows issues with receiving signals from access point and routers. In that case, you may disable or uninstall that tool and try the Microsoft Windows utility (WZC for Windows XP and WLAN AutoConfig for Vista , Windows 8 and 7).

    The steps to start Remote Procedure Call server are:

    1. Click on start and go to Run window

    2. On Run type services.msc
