Problem with internet. Certain website do not load at all. 12.04
My internet was working fine till tomorrow. Suddenly I am not able to open www.github.com, www.deviantart.com and additionally my router configuration page 192.168.2.1 . First, I thought that it would be a problem with my ISP (i have a DSL connection). I have a dual-boot system with win7, so checked the connection there. It all worked fine! Certainly it was not the ISP who was troubling, it had to do something with Ubuntu.
Problems and errors:
Github says:
This webpage is not available Google Chrome could not load the webpage because github.com took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection. Here are some suggestions: Reload this webpage later. Check your Internet connection. Restart any router, modem, or other network devices you may be using. Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again. If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the Chrome menu > Settings > Show advanced settings... > Change proxy settings... and make sure your configuration is set to "no proxy" or "direct." Error 7 (net::ERR_TIMED_OUT): The operation timed out.
The same goes with the router configuration page, while deviantart takes forever to load.
What I tried:
I read some previous posts on this topic, and I tried the following:
1) I use google chrome. I switched to firefox on ubuntu but didn't work.
2) cleared the cache and cookies, but no.
3) Set the primary DNS server to google public dns, then to open dns, still nothing.
4) Tried to set the primary DNS to 192.168.2.1 , still no.
5) I reset my router, configured it from scratch in win7 and came back to ubuntu, to see that the problem still persisted.
6) pinged www.github.com and then google.com, here are the results:

I am positive that I have no proxy and IPv6 is disabled.
Please help me with the problem.
Solution 1:
This sounds like a temporary routing issue with your ISP. You can update me if your computer is still having problems, but often these issues are certainly to do with the connection between the router and the target website.
To eliminate the browser, use wget on the command line to download the github or deviantart website. If that fails... then you need to run some diagnostics to find where the error is happening with http requests.
