How can I "turn on wireless capability" in Windows 7?
Solution 1
This happens because power management turned off wireless capability when not in use. You can change this setting:
- Open Network Connections
- Right-click on the wireless connection and select Properties
- Click Configure next to the wireless adapter
- Click the Power Management tab
- Uncheck "Allow the computer to turn off this device to save power"
Like this:
Solution 2
What I think is that you must have accidently pressed the wifi off option from "Windows Mobility center". Try opening it from "Windows Mobility center". You can open "Windows Mobility center" by opening control panel and type "Windows Mobility center".
Solution 3
Sometimes none of above will be useful because the wireless adapter has been disabled from BIOS, in this case you need to enter to the BIOS and set it as default, then login again and go "Windows Mobility Center" through Control Panel and you can turn the wireless adapter ON/OFF.
Solution 4
My wild guess: Your laptop has a software- controlled button for toggling wifi ( possibly on the keyboard) which you accidentally press, disabling the network adapter. In that case you should be able to turn it on by pressing said button.
Solution 5
I used FnF2. The F2 on my laptop has a little antenna icon. Must have hit this by mistake once!
This toggles the WiFi on and off.

On my laptop I have a strange bug or something that fairly frequently causes wireless networking to become spontaneously disabled. Network connections drop out & all available APs disappear.
Using the Windows 7 troubleshooter (right-click on networking tray icon -> troubleshoot) detects the issue & correctly fixes it every time, but it takes a few minutes. I know what the resolution is & am wondering if there is a way to (quickly) enable wireless networking in Win7?
Here's a screenshot of the resolution screen that I'm trying to shortcut to.

Paul over 11 yearsJust to eliminate the "kick myself" option, lots of laptops come with a button you can push that does an
RFKILL
, effectively turning off the wifi radio. Is there any possibility you are inadvertently hitting this button? -
Vinnyt over 11 years@Paul my laptop has a hardware switch for that functionality. It is definitely on, as wifi is restored through the OS. Is there a counter signal to RFKILL to enable?

Vinnyt over 11 yearsI do have a software switch for wifi - but it involves pressing Fn-F5, which brings up a Lenovo software dialog with options that need to be moused to & clicked in order to enable / disable wifi. I fear the chance of this happening accidentally is remote, coupled with the fact it happens almost daily.

AlexC almost 11 yearsPerfect. This was exactly what was happening. My battery is old and the power management started the computer with the wifi disabled. Thanks Sam

psmears over 10 yearsI have had this problem, and turning Wifi on from "Windows Mobility Center" fixed it. I hadn't turned it off myself (I would have remembered!), but I think the Lenovo "Access Connections" likes to turn Wifi on/off... or rather, it likes to turn it off, but not back on again.

fiberOptics over 10 yearsThis should be accepted as answer. This works for me.

Jerry almost 10 yearsThat's what was the problem on my laptop too. Didn't turn it off, but I guess it's another program that did.

Anton about 9 yearsI had to restart my computer as well after I followed the steps.

Porwal about 7 yearsThat happened! I pressed it thinking it is not working and it led me into problems. :D

JeopardyTempest almost 7 yearsAfter having this problem for ages getting worse, it appears even though I couldn't find a specific BIOS setting, resetting BIOS settings to defaults fixed it.

Scott - Слава Україні almost 7 yearsAre these the correct instructions for Windows 7? They don’t work for me. And I don’t mean that following the instructions doesn’t solve the problem; I mean I can’t follow these instructions, as written. (1) Where on the Start Menu is “Network Connections”? (2) When I open the Network and Sharing Center, right-click on the wireless connection does nothing; I have to left - click.

Stevoisiak almost 7 years@Scott My mistake. You are correct. The network connections option is not in the Start Menu by default. I made a mistake in my previous edit.
