are asus internal WLAN cards generally unreliable?

Because the one that came with my z81sp has been nothing but trouble. Sometimes when I start my computer the WLAN card doesn't boot. Device manager detects it but says that it could not start (code 10). My reseller said that a code 10 is a software issue and recommended that I try downloading the drivers or reformatting my computer if all else fails. I go to asus's website, DL the latest drivers for z81sp internal wireless, and it doesn't even give me the right driver. The DL file was mysteriously named "jackie_fang" and didn't even update my driver to the version listed on the website. Does asus always do such a half-a$$ed job of supporting their hardware?

The only way to fix this problem is to go into the bios and "load default settings." After that windows loads and everything in the device manager is fine.Then about a week or two later I get the same error in device manager. This particular problem only started about 6months after I got the computer

I reformatted my computer about a week and a half ago, partly to try and fix this problem, and I just got the same error today.

P.S. Before i figured out the trick with the bios, the problem had gotten so bad that the device manager wasn't even detecting the WLAN card

 

i have an asus a8js my wifi works perfect

 

Same here, I have an S96J with Intel 3945ABG and it works great.
