Consider a netbook - Lenovo S10e with Windows 7 and the S10 Lenovo power management tools. Machine has factory BIOS.

Fn+F5 is the key combo to toggle the wireless radio on/off.

The tool allows the disabling fine; works as expected. The problem is that the re-enable doesn't work, or is confusing on how to re-enable.

Previously tried without success:

  • Fn-F5
  • Fn-Ctrl-F5
  • Fn-Shift-F5
  • Fn-Alt-F5

Here's the onscreen display:

Question: How can you re-enable the wireless radio using the Function key on a Lenovo netbook?

This just happened to me on my ideapad. Go to Network and Sharing Center in the Control Panel, then choose Change Adapter Settings. That's where you'll see your wireless card is diabled. Right click on it and enable. Obviously a little late for the the original poster but this is for everyone else who finds the page.

The problem OP described is the same one I was experiencing on a MUCH newer Lenovo Thinkpad model (Late 2012/Early 2013), so I'll leave this here in case others can benefit from it. There's a wireless network interface you can access through the Lenovo Thinkvantage Tools. I tinkered with the green "On" switch - flipped it to off - and couldnt' get it to go back to "On" mode.

I had to enter the BIOS setup menu on boot in order to reactivate.

  • On boot, press Enter or whatever your machine calls for to enter setup (this will be displayed on the first screen briefly on reboot so act quickly)
  • Navigate to "network" settings
  • Set Wireless adapter switch from off to on.

This seems to be a glitch with that toggle switch on some Lenovo models. Why this ThinkVantage Tools (and whatever they call it for IdeaPad) exists or how it helps me, I don't know. But this wireless toggle issue is only one of many that I've had with those "tools" and "control" panels Lenovo shipped with the PC.

The message seems to indicate that the master wireless switch is turned off. You don't mention this in your post. Unfortunately, I am not familiar with the exact model, but most of these machines have a physical wireless toggle switch on them - the software controls won't work if it's turned off.
