Have had this new Lenovo T420 laptop for several weeks now, and the wireless card which worked fine at first keeps deactivating. The tiny switch on the lower right side of the laptop is turned on, and if I right-click the network icon on my taskbar 'Enable Wireless' shows checked. But the card is obviously not activated.
Function-F5 also seems to make no difference. Is this a faulty, dead card or some other setting I am missing?
Thanks much for any help.

I would check Device Manager and see if the card is recognized there when the card turns itself off. It should be under the Network Adapters tree. I would also recommend making sure the BIOS and wireless drivers are up to date just to be sure. Both of those can be found here. Also, one question: what operating system are you currently running?

Hi, running Open Client Red Hat 64. I've already ok'd to be moved to the Linux discussion forums if it helps, however, this looks like something to do with the hardware itself......as I've seen other reports of this happening on the web with Windows.
I do have Windows Virtual 7 running on the machine also, and do have Device Manager there. It shows two adapters, AGN Virutal Network adapter and Red Hat VirtIO Ethernet Adapter. Both are enabled and running.
Yet the icon in the lower right indicating signal strength that one was (when wireless was active) still not there, and if I unplug the landline, I lose network.
Is there a way to turn it on in the BIOS maybe? Thanks.

I have looked in Virtual Windows 7 and there is no Power Management tab under Device Manager.
There is a Power Options item in the Control Panel but it only allows you to check or uncheck "High Performance". HP is currently checked :/
