HP Pavilion — a847c Desktop – MS Windows – “Other Devices” “Ethernet Controller” –> Yellow Mark
It all started one Saturday morning, actually this morning (Sat 2010-10-02) to be exact. A friend’s HP Pavilion hard-drive crashed and a new drive had been placed in for a couple of weeks now. But, only now completed MS Windows XP install. Only God knows how long it takes to apply all the security patches one has to download and apply these days.
Anyways, most everything was done. But, still there was a yellow exclamation mark that wouldn’t budge in the Control Panel \ Device Manager applet.
Visited HP’s Support site numerous times to see if I could find a matching driver, but no luck.
Reviewed, the Product Specifications – HP Pavilion a847c Desktop PC Product Specifications (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00280716&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN), but very little detail regarding the Networking “elements”.
The specification per-functionary makes mention of “Network (LAN) – Integrated 10/100 Base-T Networking Interface”. And, that is it.
On HP’s Support \ Drivers web page , the closest we came to the drivers is:
HP Customer Care > HP Pavilion a847c Desktop PC > Microsoft Windows XP > Spring 2005 Original Network Adapter Driver Collection
but, even after downloading the driver, extracting the zip file, the extracted files lacked an install program (setup.exe) and the accompanying documentation yet failed to draw us any closer to knowing if we had the needed files.
So reached back and brought out an old trusted friend and companion (Halfdone Development – Unknown Devices
The “Unknown Devices” application immediately recognized the device as an “Atheros AR5212 Wireless”. So off I googled for that manufacturer and driver, but all
to dead ends. It appears that the driver is not publicly published, nor supported by the Vendor.
Googled some more and found a couple of Applications that would detect the “unknown devices” and match them with corresponding drivers.
Some of the Applications that were downloaded and tried are: DriverMedic and Unible – DriverScanner. But, as they were both commercial applications, could least afford them; at least on a broke Saturday morning ( on the 2nd day of October).
Once the compressed\zip file is downloaded please extract it and return to MS Device Manager where will be able to affix the newly downloaded drivers to the “Ethernet Controller”.
So that is the long story. A shorter story and possibly more official driver can be gleaned from this next paragraph.
