Was this wireless card the the original one that came installed when you bought your laptop?
Has it worked before ?
If it came already installed, where did you install the drivers from?
Please, check this link below as it may help you to resolve connectivity issues:
You can also do the following:
a. Press Windows key +X and select Device Manager.
b. Right-click the device and click Properties.
c. On the General tab of the device Properties dialog box.
d. Check the status of the device and let us know.
It is the original card.
Yes, it has worked before, without issues. As of late, it's been trouble.
I used the Intel driver update utility to get the latest driver. I did get one from Dell but that didn't work either.
It's not really a connectivity issue, it's a detection issue. The wifi card will not be detected by the computer if I reboot it, or if I do not have the power plugged into the wall. If I'm cold booting it with it plugged in, it works fine.
Since I rebooted, nothing is showing in Device Manager.
If I cold boot (with power plugged in), it will show up in Device Manager and work fine.
