Wireless suddenly is disabled

Wireless has worked great for months until the other night. The laptop was left on (plugged in), the lid closed. In the morning I opened the lid, typed in my password and there was no wireless network connection. I rebooted several times. I right clicked in the tray icon and the “Enable Wireless” box is unchecked and grayed out.

I reran Network Settings several times. It shows the card: PRO/Wireless 3945ABG. But clicking finishing doesn’t do anything. My wireless seems to simply be disabled. A setting somewhere has changed and I’m not sure where.

One last thing. I looked through the var/log/messages and found this line:

Scrolling back I don’t see that reference ever appearing before.

Turn your switch on.

I didn’t know I had a kill switch and am not sure how to identify it. Thoughts?

Since I have not been told what kind of laptop you have, I am at a
disadvantage. On my HP, there is a slo=ide switch on the front. On
other versions, there is a button just under the screen.

Sorry I buried my laptop (Lenovo R61) at the bottom of the original post.

Heaven’s that’s embarrassing. There is a switch on the front that simply got knocked into the off position.

Well, I learned a few things along the way.

Thanks! rotfl!

Many HPs have the button on the side. It has an icon of an antenna emitting waves. Often, it is illuminated when it is on.

Being on the side, it sometimes gets pressed when you pick up the laptop.

Good luck.

After wasting 90 minutes on this myself…

I want to point out that the Dell Latitude D830 switch is on the left :slight_smile:
