Atheros And Bluetooth Device Code 31 Errors

Question

Hey Guys,

I woke up this morning and struggled to get internet access on my laptop. Aftter running a few troubleshoots, I got two errors:

1. Atheros AR9285 802.11 b/g/n Wifi Adapter (Code 31)
2. Bluetooth Device (Personal Network Area)

Windows says it has resolved the problems and the drivers are up to date, but the problem still remains.Ive tried to go through D-links's website to get a driver but the pdf file says its all done through the OS. And ive also downloaded the appropriate driver from HP's website.

Ive got a D-link DIR-655 router with Windows 7 OS.

I've got no idea what to do!! Any information would be greatly appreciated.

Thanks.

Answer 1

Hi,

I would run SFC and CheckDisk as above to see if there is any file or system corruption.

Glad to have helped.

Answer 2

Hi,

This device is not working properly because Windows cannot load the drivers required for this

device. (Code 31)

Windows was unable to load the driver. Try updating the driver for this device.

On the General Properties tab of the device, click Troubleshoot to start the troubleshooting

wizard. (Control Panel - Device Manager)

Try a System Restore back to before this happened.

If needed :

Did you actually install the drivers from HP using this method?

Download - SAVE - go to where you put them - Right Click on - RUN AS ADMIN.

You can try these and then try installing them again.

Do these to clear corruption and repair/replace damaged/missing system files.

Run DiskCleanup - Start - All Programs - Accessories - System Tools - Disk Cleanup

Start - type in Search box -  COMMAND   find at top of list -  RIGHT CLICK  -  RUN AS ADMIN

sfc /scannow

Then run checkdisk (chkdsk).

Here methods to install most drivers so use the complete method if needed.

This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.

For each driver in the list, additional useful information is displayed: load address of the driver,

description, version, product name, company that created the driver, and more.

http://www.nirsoft.net/utils/driverview.html

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.

Control Panel - Device Manager - Display Adapter - write down the make and complete model

of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate

Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -

Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party

with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device

Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for

BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after

each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually

shows up. This is because some drivers rollback before the latest is installed (sound drivers

particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check

manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Hope this helps.

Installing and updating drivers in Windows 7 (updating drivers manually using the methods above

is preferred to ensure the latest drivers from System maker and Device makers are found)

If you update drivers manually then it is a good idea to disable Driver Installations in Windows

Updates, this leaves Windows Updates ON however it will not install drivers which will usually be

older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then

go look for new ones manually if you wish.
