Today, after using the newest stable release of Clonezilla -version 2.4.2-32, in boot CD form- to make a disk clone of my laptop’s (HP 2530p) hard drive, I found that the internal wireless LAN adapter was inoperable. Even the LED light/toggle button was stuck on the off/amber color.
After trying all the standard things in terms of software and hardware, and some less than helpful Googling, I was only able to find that it may have been hard locked by the Linux kernel used on the boot CD.
Knowing nothing about Linux or its drivers, and using Windows 7 on the laptop, I figured I may just be fucked. I tried reinstalling the windows driver, system restore, and everything else you can in Windows 7, and I also physically re-seated the card and its antenna connections.
I tried a startup test in the Bios and found no issues. I had already tried disabling the card and re-enabling it in the Bios, with no effect. But, all that gave me the idea of doing a complete reset on the Bios settings themselves.
Once I reset the Bios to the default settings, the WIFI card was working normally again in Windows. The toggle switch and indicator light were able to change to the on/blue position, and the wifi connected like normal in Windows. Beware using Clonezilla on your laptop! Hope this helps.
I discovered this highly useful piece of freeware in my search for wifi signal detection tools. It has been a real life saver, and is very helpful program whether you are war driving for fun, looking for the best spot to “borrow” internet from the neighbors, aiming mid-long range antennas, or simply trying to optimize your home or office Wifi signal.
From the Wikipedia entry:
NetStumbler (also known as Network Stumbler) is a tool for Windows that facilitates detection of Wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards. It runs on Microsoft Windows operating systems from Windows 2000 to Windows XP. A trimmed-down version called MiniStumbler is available for the handheld Windows CE operating system.
The software has an adjustable refresh rate, and when set to the fastest the software is far superior to the stock Windows wireless network detection. You can make fine adjustments to your layout and watch on screen to see the differences they make almost instantly. It has a plethora of options to fine tune your connection.
It is worth noting, though, that the software will not actually optimize or even connect to any networks for you. It is used rather to help find that “sweet spot” for your antenna, then you are to use either Windows or your adapter’s software to connect to the network.
