I am always having internet connection problem. One of them is that once I turned on my pc and start connecting to the internet I’m getting “could not connect to server”. Then the internet will come back after a couple of minutes without me touching it. It looks like it’s an intermittent connection.
One day, I got so irritated about this and I run the help function on the windows 7 feature. After it checked my connection the result was “dns error”.
I don’t know what that means. I followed what was instructed to do but none of them works.
Getting DNS error when trying to go online
Has this always been an issue with your computer or did it just suddenly start happening? If this has ALWAYS been happening then there could be a problem with you ISP (Internet Service Provider). There are also several factors to consider when it comes to problems with the internet. We’re going to have to go through the basic steps before proceeding to the advanced steps.
Since restarting the computer doesn’t solve the problem, try resetting your modem. Leave it off for 10 seconds before turning it back on. If you are using a router, turn both you modem and router for 10 seconds before turning them back on. Wait for your computer to get an IP address and try surfing for a few minutes to check if it is stable. Also, make sure your cables are properly connected.
Update your router’s driver and restart it again along with your computer and see if it changes.
If you are connected wirelessly, check if there are any static disturbances around your wireless modem/router like speakers or anything that has magnets. Try surfing as close to your wireless modem/router as you can and see if there is some progress.
Try to connect directly to the modem and bypass the router completely to see if you can connect to the internet without the intermittent connection.
If it doesn’t still work try connecting it to a different PC or Laptop and see if it is stable there. If it is, then it is the PC that needs adjustment and not the ISP
Like mentioned earlier, it could be an issue with your ISP. Give them a call and ask them about any disturbances in your area. There are ways they can fix this from their side by doing a “Port Reset”. Check to see if this solves your problem.
If none of these work for you, try the following solutions.
There is a possibility that your DNS settings are entered incorrectly. Click on “Start” and Enter the command NCPA.CPL. Choose and right-click the local connection you use, and click on “Properties”. Choose “Internet Protocol Version 4(TCP/IPv4)” from the choices and click on “Properties. Change the “Preferred DNS Server” to this: 220.127.116.11 and then click on both “OK”s. Also try 18.104.22.168 if the previous one doesn’t work. If it still doesn’t work undo the changes made before proceeding to the next step.
Do you have any VPN software installed that starts upon start up? If you do, disable it and see if it works, if it still doesn’t work uninstall it and try again. Uninstall it only if you have a back up (just in case you need it).
See if you have “Microsoft Virtual WiFi Miniport Adapter” enabled. Disable this and try again and see if this resolves your issue.
If none of these work you can go ahead and do a “System Restore” to a restore point that your internet connection was working properly. There is a small chance that an application is interfering with your internet connection.
I hope one of these solutions have solved your problem, post here anytime, I will keep an eye on this thread so we can work toward the perfect solution.
Getting DNS error when trying to go online
DNS issue can be caused by 2 things, a computer related DNS software issue or the DNS problem with the Internet Server.
DNS is domain name server – designed to translate IP Address to a website. Instead of putting numbers on the web browser's address bar to display the website, you can use DNS or a web address to make it simpler and easy to remember.
First of, contact your Internet Service Provider for possible DNS server issue in there end. Let them walk you through doing the troubleshooting if possible.
You can also do the dns look up
Go to Start, StartSearch
Type cmd and press enter
On the command prompt type ipconfig/flushdns
Then press enter on your keyboard
This should clear all DNS issues in your computer
You can try this also
Type this in the command prompt window tracert http://www.thewebsite.com

If it does, the problem is the web server itself. Contact your ISP.
