I get many "Server not found" errors, sometimes I have to refresh a page 10 or more times to access it. It's as if the browsers immediately gives up trying to connect to webpages. In Firefox, it says "Looking for: www.****.***" and it immediately displays the "Server not Found" page. Whenever I'm using any Bittorrent client, I can't even go to any page, no matter how much I limit the bandwidth use and connections of the client.
Things I've tried so far:
* Safe Mode with Networking. I still have the issue.
* Virus Scan. Scanned with McAffe, Nod32, online scans and posted a HijackThis log file in another forum. My system is 100% clean.
* Flushing DNS
* TCP Optimizer. Tried several different setting, including restoring Windows default.
* I've checked the modem and the connection in several other computers and laptops. In all of them it works perfectly fine.
