Acer Aspire 5735Z Wireless issues

Are there wireless sources in your area (presumably you have a router yourself and its wireless is enabled)? Are you satisfied that you've investigated Vista's wireless networking fully ? Have you checked Control Panel, Device Manager to see if the wireless is working normally ?

If so I think your next stop must be the Asus website to download the correct driver.

I think I would first check the base of the Acer to see if there's a hatch which allows you to access the wireless adapter -- if it's a mini-PCI, it's feasible it has slipped out slightly. A but unlikely though as the sort of bash needed to do that would probably have damaged the computer.

Otherwise, uninstall the driver and the device in Windows (if appearing in Device Manager, Hardware with a warning flag) and re-start the computer.

It's possible that Windows is trying to install its own driver -- you probably need the proper driver from Acer (I don't know why I put Asus in my earlier post -- they are different companies).
