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.
