I am having a strange problem with my laptop.I am using Ubuntu 12.04 on Dell Inspiron 1545.I use internet through wireless router.I have been using internet successfully without any kind of problem but now i am facing a weird problem. The problems are:
My laptop is not opening Facebook.sometimes it opens login page but after entering usrname and passwd and clicking login.it just shows "connecting" message for a while then shows "Request time out" message.
Same problem is with hotmail except hotmail is always opening its login page.But nothing furthure.
The strangest problem is with youtube. I am able to see videos without logging in. But after login youtube shows a message "An error occured please try again latter".
And every browser on my laptop is showing same problem including firefox, Chrome, Chromium.
And i have windows 7 too on the same system. And i am not facing any problem on windows 7.
