Wireless connection dies after wake up

[Wrighteous]

Hi, all. New here.

Brand new Asus U20A running Windows 7 Ultimate 64-bit.

This problem only occurs when the laptop is unplugged from AC power, so far. If I close the lid to hibernate or sleep, my wireless connection will not reconnect upon reopening the lid. I change the Power Saving option to keep the computer from turning off my wireless adapter. To no avail. Changed the lid-close settings to keep the laptop from sleeping/hibernating, but that doesn't solve the core problem.

After reopening the lid, as well, the FN+F2 key that would ordinarily toggle a connect/disconnect option on the wifi adapter does not help. Both the on-screen option and indicator light on the laptop respond, but it does nothing for my connection.

I can't even figure out in Windows where to turn on my wifi adapter without Troubleshooting, which doesn't help most of the time, aside from telling me to "plug in an ethernet cable". Well, duh. It won't even give me the option to connect wirelessly.

Ultimately, rebooting gives me my connection back. But this is not a solution. I should be able to reopen the lid and be connected, whether waking up from hibernate or sleep.

There is nothing wrong with my wifi service, so I can rule that out. There are multiple desktops and laptops that are working fine on the LAN.

My adapter is the Atheros AR8131 PCI-E Gigabit Ethernet Controller (NDIS 6.20) with an updated driver.

Please help! This is a fearsomely annoying problem.

There's a place to change how power management controls the adapter under control panel. Go to Network and Sharing, then Change Adapter Settings. Look for the adapter then right click on it and select Properties. Click the Configure button and find the Power Management tab. Try disabling the option that allows Windows to turn off the adapter to save power.

Yeah, I tried that one already. Still no luck. I'm playing with my power settings utility that came with the notebook to see if there are any other options to keep the adapter on.

Hopefully there's something in the laptop's setup there somewhere.

Yes. Hopefully.

Have you tried a disable/enable to get the adapter back vs a reboot?

Look At Software

Check to see if there has been software installed by the factory for power management.

A lot of laptops come with software that overrides windows power management, look at the program list it would be in a folder that should say Asus then look for power management.

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.:huh:

So your connection doesn't reconnect after the system goes back on, with the Start the connection automatically option ticked?

 

[Wrighteous]

That's correct. Problem still hasn't been resolved. I'm furious with it.

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
