If you have to wait too long until a web page is loaded in your IE browser, it may be caused of wrong LAN settings. Solution:
Click on Start button –> Control Panel Doubleclick ‘Internet Options.’ A dialog window is opened. Click on Connections tab. Then click on LANsettings button.
In the new window UNCHECK the Automatically detect settings check box.
Click OK and restart computer. So your browser will not attempt to detect proxy setting anymore and will load the webpages normal.
