Windows 7 32 Bit - Wireless Driver Intel 7200 AGN - Code 31 Error  

Hi,

I recently did a clean install of Windows 7 Home Premium 32 bit on my system, I backed out the data but did not back up the drivers.

Now i see that everything else seems to be working fine except the Wifi function. The wired internet works fine. I can see the various wireless network adapters like Intel 5300 AGN, Intel 5100, Intel 7200 AGN and I have also installed the latest drivers for the same. But i keep getting this Code 31 error which says "The device is not working properly because Windows cannot load the driver"

Can someone pls help me troubleshoot this. I looked around on the internet but am unable to fix this. the machine is Acer e727 and I have a 1 GB RAM.

please let me know if you need more information.

Thanks for that. I used it to install a new driver for my wifi adapter but the problem still shows. Error 31 "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"

I believe this has to do with something other than not having the driver file.

I have put in the screenshot here. If its a hardware issue, I am wondering why would it occur after the windows reinstall. The previous OS was Windows 7 32 bit as well. Also the wired internet works fine.

Hardware ids are

PCI\VEN_10EC&DEV_8171&SUBSYS_818610EC&REV_10
PCI\VEN_10EC&DEV_8171&SUBSYS_818610EC
PCI\VEN_10EC&DEV_8171&CC_028000
PCI\VEN_10EC&DEV_8171&CC_0280

I installed the chipset drivers and now the realtek wireless driver. But no change in the device manager. I restarted after the chipset driver install not after the realtek. (I dont think i have the realtek adapter on my system?)
