HP's website has the drivers and utilities for that laptop. I suggest download them all and install them again. Esp. the utilities, since they control the special function keys on the keyboard.
I went to HP's website, and downloaded all the network/internet updates. I also ran a scan to see what I needed updates and downloaded those updates.
After some more research I found this sticky on HP's forums: http://h30434.www3.hp.com/t5/Wireless-Internet-Home-Networking-e-g-Windows-8/Consumer-Notebooks-and-Windows-8-Wireless-BT-WWAN-amp-Radio/td-p/1984915
Apparently, this is a widespread problem. AND, the steps provided in the sticky above further create problems for many users. The BIOS update has changed the wifi button into an airplane mode button. Unfortunately, I discovered this after I downloaded it.
According to the steps in the sticky, I have completed the first two steps. I installed the BIOS update, verified the "Unknown Device" was present, and installed the "HP wireless button driver."
The third requirement: asking to install the updated wireless driver is the problem.
I have the "Intel Centrino Wireless-N 1030 802.11 bgn," and the updated driver, labeled "SP59925", is "not yet available."
I have downloaded the most recent driver listed on HP's website and Intel's website without either helping anything.
So now, I still am without wifi, my wireless button now controls the airplane mode, and HP leaves my hanging.
Also, my model number is: dm4t-3000 (beats edition)
It makes it easier to find information using the model number I discovered.
Any workarounds??? No one on the HP forums seems to know anything.
