|With regard to Praveenvapn's two posts. I'd ignore them and respond to wanderer's.|
First of all, turning the NIC to half duplex is not likely to fix anything. If the NIC has been set to "auto", and the port it's connected to is also set to "auto" then they will be operating in full duplex mode. Changing one side of the connection to half duplex without changing the other side will create more problems. Chances are this is a SOHO Router or SOHO Switch that doesn't allow for changing duplex mode on ports so all you will do if you follow this advice is as I said, create more problems.
As for un/reinstalling the web browser.........well, there are several troubleshooting steps to go through before trying that. But, you need to do as wanderer requested since that is Step 1 of the troubleshooting process.
Praveenvapn, if I may make a suggestion, slow down on answering questions. Hang out here a bit, watch some posts, read through some old ones...learn some stuff before you begin answering people. We appreciate your trying, but in this case, both suggestions were a waste of the OP's time. Just for the record, I'm not trying to make you feel bad or single you out. It's just that misinformation is worse than no information and what you said is only going to confuse the issue at this point in time.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
