I'm also experiencing that with windows vista 32bit on my client's asus u20a. i made a step by step installation of the drivers and it seems that the wifi connection is ok if you don't install the wireless console program which also install the bluetooth stack driver.

once it's installed, when you go to standby mode, and come back, somehow the wifi chip get's stuck in the sleep state while the bluetooth can wake up. i'm still verifying if there's another bluetooth driver that we can install in lieu of the wireless console. for now, without the bluetooth stack driver, and only the atheros wifi driver running, it's working fine even from a long standby. hope that helps.

Is there a way to uninstall the bluetooth stack driver without altering the wifi driver settings?

If you look at the properties for the adapter in Device Manager, can you get a screen shot of all the options? I've seen other devices that have a problem with resume and the wireless adapters. Depending on how much control they allow in the properties there may be something there we can fiddle with.

i think you should try a clean install and just don't install the usual sequence of the drivers from the disk. in this way, you won't have sleep function (because the ATK driver WILL KILL THE WIFI).

maybe asus might come out with a patch or something soon....

Having the exact problem with my u20a, has anyone found any fix? Is this more likely to be a software issue or hardware..., not sure if calling asus up for a repair would do any good...

btw, I found that waking up the laptop quick enough you will get wifi back, but for a prolong period (>1min?) I will lose it....

EDIT: Actually, I went into device manager (with Bluetooth turned on) and removed any trace of bluetooth device and their drivers. Then do a rescan of new hardware, let window find the drivers etc (There will be some that can't be found, called "Bluetooth Peripheral Device" on mine with yellow exclamation beside it). I left them as it is and that seen to did the trick, the wireless is working again.

EDIT2: It looks like the fix was not perminant, wireless disappeared again, but the wireless/bluetooth button was working, only turning on the bluetooth tho
