If you have an older HP computer, you may sometimes get the following error when booting up your computer:
Error Message: 104-Unsupported wireless network device detected. System Halted. Remove device and restart.
This is one of those really technical errors and it’s unfortunately not easy to fix. However, it’s worth a shot before sending your computer back to HP or dishing out lots of money to the Geek Squad.
There are a couple of steps you can take to try and fix this issue on HP laptops and notebooks. Good luck!
Method 1 – Update BIOS
Firstly, if you can get past the error and actually boot into the OS, then you want to try and download the latest version of the BIOS. If you can’t get past the error, make sure you try to load the computer in Safe Mode and see if the OS loads.
Another thing you can try is to enter the Setup and disable the wireless component on the laptop. Then try to restart the computer and see if you can get past the “unsupported wireless network device” error.
If so, go to the HP update site (http://www.hp.com/#Support) and type in the model number for your HP laptop. Download the latest version of the BIOS and install it!
Method 2 – Reset the BIOS
If that doesn’t work, you’ll have to try resetting the BIOS. In order to do this, you have to restart the HP computer and then press the F10 key while the HP logo is showing. Press it a couple of times during the initial boot up if you can’t get in immediately.
Now go to the Exit menu and select Load Setup Defaults. Finally choose Exit saving changes.
After resetting the BIOS, you’ll have to perform an OS repair install. This is a pretty long guide in itself, so I’ll direct you to a great post that walks through each step in performing the repair install. Not that it will NOT delete any of your data or programs.
Method 3 – Use Knoppix Linux
If the two methods above didn’t work, you’re kind of screwed now. There is one other thing you can do, which may or may not work, but it’s really really technical.
Basically, you have to download Knoppix Linux and burn it to a CD. Pop in the CD and wait until you see the boot: line. At this point, pop in the wireless card and press Enter. Knoppix will detect the card and it should load up fine.
Now, once Knoppix is booted up, you need to click on the Penguin in the taskbar and select Root Shell. Type in the following command:
You’ll get a list of ethernet adapters and you should see one with a bunch of wireless parameters. Now type the following command where X is the index of the wireless adapter:
#ethtool -e ethX
Now type in the following commands, which will help write to your EEPROM. Note that now you can really mess up your computer, so be careful!
If that works ok, now type in the following commands:
#tar xvzf ipw2200.tar.gz
Almost done! If you’ve gotten this far, things are looking good. Type these commands if your card is from the US:
ethtool -E eth0 magic 0×2200 offset 0×8 value 0xf5
ethtool -E eth0 magic 0×2200 offset 0×9 value 0×12
ethtool -E eth0 magic 0×2200 offset 0xa value 0x3c
ethtool -E eth0 magic 0×2200 offset 0xb value 0×10
Now reboot the computer and hopefully your Error 104 is gone forever! Overall, this last method is really hardcore and should only be done if you know how to restore a computer from scratch or you’re not worried about losing all your data!
