Internet Explorer refuses to render Outlook web app because of ActiveX

On Google Chrome and Firefox I had no problems with navigating to Outlook web apps. However, when using IE 9 I kept on getting the warning that the ActiveX setting was not enabled. There are quite  a number of hints on the Internet about this problem. Apparently we are not the only one having this problem. The solutions on the Internet did not help us. In the end we had to use a mildly insecure solution. Under options  in IE one can adjust the security of different zones. Go to Trusted Sites and see if the site supplying the ActiveX is in that list. If not: add it. >> >>

What chipset is in your wireless adapter?

Wireless adapter
In case your operating system (OS) is a member of the Windows family any built-in wireless adapter will be recognized and functioning by the OS, and any external USB wireless adapter will either run out of the box, or run after you installed the driver from the CD coming with the USB adapter. In case of an Apple laptop the OS will also know how to deal with the wireless adapter. This simple install procedure is for 99% of the users a satisfactory situation. However, not if you want to fully explore all the wireless stations in your neighborhood. For an in-depth exploration you will have to be able to put your wireless adapter in "monitor mode", rather than in the default "managed mode". You will have to use as OS a member of the Linux family  if you want to put your wireless adapter in monitor mode. Of course your reason for using Linux could as well be that Linux is your favorite OS anyway. >> >>
