Today morning my laptop was showing issues with connecting to my home WiFi. While checking for the reason, Windows Network Diagnostic showed an error message "Wireless Network Connection" doesn't have a valid IP configuration. This laptop was working fine with the same WiFi in last week but today refused to connect to the same. Since there was no proper connection between my router and laptop, Auto configuration IP address (APIPA) was assigned to it. This tutorial is based on the troubleshooting steps I have done today to solve the problem. If you ever face this issue, I hope this guide will help you to fix it. This guide is divided in to two parts where the first part explains automatic Windows Diagnostics. Second part is for those who couldn't fix the problem using automatic diagnostics.

As part of a promotional package, I have received one free email account from GoDaddy while purchasing a domain name from them. Since I have been fed up with remembering a lot of email addresses, I decide to configure the new address with Email Client installed on my laptop. So at least I am sure, I won't miss any important messages. The procedure to setup Email Client with GoDaddy webmail is very simple. However, if you don't understand the terms incoming and outgoing servers, or don't know where to find them, it may be a little bit difficult. If you are one among them, this tutorial can help you. In this tutorial I used eM Client as my desktop email client to download and store messages coming to my GoDaddy webmail service.

One of my websites was hosted with an ordinary plan from a less popular company but I have bought a new premium hosting from GoDaddy due to the high potential of that site. However, after adding the domain name to the new plan, I have received an error message "This Domain is Already Assigned to an Account" and failed the process. After contacting GoDaddy technical support only I came to know that the previous company I used to host my website is one of their resellers. Unless I have released my domain name from their account, I cannot add it to my current hosting. I followed the procedure to remove SysToSys.com (domain I own )from the reseller hosting using the steps provided in the support link below.

If you are really concerned about Monthly Bandwidth Transfer, you can optimize a few settings on your hosting  and save a little of it. If you do not know the meaning of bandwidth, it is nothing but the data transferred from the server to client computer. Bandwidth is used to show a web page and all its content to a user. If all the components like video, flash, images etc are hosted with your web server, more bandwidth will be taken to load them on browser. As the amount of data transfers to the browser from server increases, it consumes more of it. This tutorial explains some simple tips to reduce the server bandwidth consumption.

For the past one week, I have been noticing slower Internet speed on my home computers without any reasons. I am not using any torrents or other bandwidth consuming tools on any of the PCs but recently one representative from my ISP informed me about over bandwidth usage. I inquired her about my reduced bandwidth but she said everything from their side was working perfectly. Since the ISP side is working perfectly, problem must be from our end. Perhaps some other user is using our wireless anonymously to access Internet and may be downloading large files. Airtel is my Internet Service Provider and my experience with them is so far good. I have been getting almost the same speed they offered and it is the time to instigate the culprit who uses my home WiFi. Airtel supplied D-Link DSL 2730U modem and it doesn't have any feature to find the log of connected devices. So I have decided to change the current WiFi password and allow only my home computers and laptop to join the WiFi by u…

Today I saw one strange redirection issue with CoreNetworkZ.com, where its bare address is not opening or redirecting to the WWW version. At first I thought it might be an issue with my Internet Service Provider but their support team said that everything was working properly at their side. While searching with popular webmaster forums, it is convinced the issue is not with blogger custom domain name settings. As a last resort I contacted the live chat support of my domain registrar. CoreNetworkZ is registered with NameCheap, one of my first choice domain name registrars. While troubleshooting the issue with the support person, he informed me that it was due to DDoS attack against their default DNS server and they might want a little bit time to resolve it. He suggested me to change the current DNS server I selected for my web address to backup DNS System. Though changing current DNS server may help to escape from DDoS attack, it can take up to 24 hours to see the result. To see the…

GoDaddy is one of my favorite domain name registrars and I have been using their service for the past five years. They offer low cost domain name registration for the first year with a rate not many other registrars cannot offer. I have been using this privilege ( like 108 Indian rupees for a .com domain ) to register names for my projects but recently I faced an issue while placing the order. The system is not letting me to complete the transaction. At first I thought it is a common bug but sooner I discovered the true nature of it. Whenever I use GoDaddy promotion code to cut down the price, system shows error. Whenever I click on Place Your Order button, it responded with the following message.

There is a problem with the information you provided. Please ensure all fields are completed properly.


So many thoughts went though my mind after seeing this alert. I checked this situation without using their promotional code and that time everything was fine. There was no error message whil…
