So when people at work surf porno all day (and they do), the IT staff are sitting
around giggling about which staff are visiting necrophilia.com and donkeyfriends.com.
What you want to do is possible but it's critical to understand there are two types of "wireless".
"Wi-Fi" is a short range networking connection. It connects you to a nearby WiFi router that
connects to the net. This is like in coffee shops, and some work places will have it.
3G Broadband is a wireless internet connection for (usually) laptops. It is a little card/key
that plugs in to the side of your laptop. It is doing the same thing as a cable modem :
it connects you over the phone carrier to the net.
If you get a 3G connector for your laptop, you will be ok. But, understand that will be $20,$30,$50
per month just like a normal broadband connection. Also if your laptop also has a WiFi interface,
you would have to disable the WiFi while at work. Not hard, in control panel, or just leave off always.
This is because the computer will takes the fastest path to the network. So if the WiFi is faster
than the 3G, it will go thru the company Wi-Fi network (if they have it). Often the IT staff will have
one for their own use.
So, yes, but you need to pay for another broadband connection for the laptop and disable WiFi.
And even so your ISP always sees the same type of list of file names above.
So never visit anywhere bad on your own ISP account.
