Start over fresh to run Acer Restoring a system to factory load

or get the superior Clean Reinstall - Factory OEM Windows 7 following the steps closely especially about how to handle drivers in Windows 7.

What did you try, and exactly what happened?

We can't help you if we don't know the exact failure point, error message or other information besides the lame "It didn't help."

Plug in by ethernet cable, run Windows Updates to install all Important and Optional Updates after enabling Automatically get recommended drivers and updates for your hardware (Step 3). Make sure the wireless is turned on, check if driver is installed and working in Device Manager.

If the problem still exists after a full format and reinstall of windows, then it sounds like a hardware problem, try a USB wifi stick or get the the wifi card in the laptop replaced

Does it say both Adapters are working in Device Manager?

In Control Panel>Network and SHaring Center>Change Adapter settings, are both adapters enabled?

When you hover the mouse over the connection icon in bottom-right System Tray, what does it say?

Rightclick on the connection icon in bottom-right System Tray, run Troubleshooter.
