Many a times we run into a very unique problem wherein we see that though we are connected properly to our internet service provider (ISP), but we are able to access a few sites only while others may not load or return a “host not found at given address” error.
Typical symptoms of above problem will be”
1. The connection to the ISP is shown as connected on your PC.
2. If you are connected through ADSL modem, you see the DSL light glowing constantly as well as the internet LED blinking, showing internet activity OK.
3. You are able to see the web page of few sites, while others may not load at all.
4. Your internet access time is very slow for certain sites.
5. Till very recently you had a perfect internet connection and suddenly you are not able to access certain sites etc.
Above may be a result of improper DNS i.e. Domain Name Server settings in your network settings.
Generally we are provided with a DNS server setting which our PC fetches from the ISP at connection start up. God forbid if the ISP’s configured DNS server goes down, then you run into the above kind of problems.
Thats too much for the explaination of the problem, but whats the solution????
All you have to do is to set up your DNS entry to a public DNS may be one hosted by Google (at 184.108.40.206) and this is how you do it:
On Windows platform:
1. Open Network Settings in Control Panel.
2. Right Click and select properties on the network adapter, through which you connect to your ISP i.e. through which you access your internet connection. It can be the wireless adapter if you connect through wi-fi or LAN/ ethernet card if you connect through UTP cable.
3. A pop up window will show you certain properties of your network adapter. Scroll down till you see an entry “TCP/IP”. Select it and click on properties button below (which gets highlighted as you select “TCP/IP”)
4. Another pop-up window will show you the IP address and DNS settings.
5. Go down to the Domain Name Server (DNS) address. Generally it will be selected as “Obtain automatically from ISP”.
6. Change it to “Use following DNS server” and punch the following values into the address field:
7. Click on OK buttons till you reach back to the network connections window.
8. Now you may check for loading of websites in your browser, and the problem should be resolved.
