The usual key combo to toggle the wifi on/off is FN+F2 or just F2 if your computer is not setup with multimedia as the default function key behavior. You might have a connection problem to your wireless network and/or router. Try using the Network & Sharing Center in Win 7 to troubleshoot your connection.
Posting in the Networking forum might get you more help.
2. I ran the diagnostic tool and it said the radio was off. I then pressed the wireless switch (above the F8 key on my XPS 16) a few times and got a new message window from Intel that had not been there before. Then the Wi-fi indicator came up without the X and all the wireless networks in my area were again listed.
3. Lastly, I noticed an "Intel My Wi-Fi Technology" icon in my systme icon tray that allows me to enable/disable the wi-fi. I haven't tried disconnecting my ethernet cable yet, but I am hopeful that since I can see my neighborhood networks that it will work.
On the 1645, look for the antenna button directly above F8, which controls all the radios, including bluetooth and wireless card. If this is off, no wireless networks will appear.
I had a similar problem that I just resolved by turning the radio on via this button.

I had the exact same problem with my Intel Wireless 5100 in my Dell XPS 16. Here's what I did to get the radio to turn on:
1. I updated the driver to version 13 from the Intel web site: http://www.intel.com/support/wireless/detect.htm
and installed the Intel® PROSet/Wireless Basic Enterprise Application from the Intel site (I have Windows 7 64-bit, yours might be slightly different)

I found a round about way to fix it. When the computer starts, hit F2. Change the wireless settings to
1st line chg to Blue + LWAN
only enable LLAN and the other two disable.
Also chg the features on pwr settings to not change wireless if you run out of batteries.
