I have an HP Pavilion dm4t Product number: QA703AV
It is running Windows 8 (64-bit)
Since the most recent windows update (2 or 3 days ago), my wifi has been having problems. The button on the keyboard is always white (on), but the wifi icon has an "X" and is not connected. I have tried disabling and re-enabling it in network connections/adapters. I have gone to the Intel website and updated all the drivers. I used the Intel PROset/wifi connections utility, and ran a diagnostic test. It said the radio was off. Within the Intel wifi connections utility I found the ability to turn the radio on/off nowhere.
When this happened the first-time, 2 days ago. I had to restart my computer 2 or 3 times and eventually turn it off and take the battery out for the wifi to work again. Yesterday it stopped working again,and I tried that method to no avail.
Also, the Intel PROset/wifi connections utility is nowhere to be found on my computer now. I think I somehow replaced it with another Intel thing when I was double-checking all my drivers on their website.
My LAN is working fine, the wifi radio is off, and I cannot find a way to turn it on.
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.
