I just downloaded the windows 7 upgrade on my acer netbook and now I can't get my wireless connection to work. (the old OS was XP) I have tried re-installing the driver but no luck! Help!

Please explain the issue a bit more.

Are you not able to find the wireless signal at all now or they are visible but you are not able to connect?

If they are not visible, then have you checked the device manager and see if there is any wi-fi card mentioned under Network Adapters or not or is there any question mark or exclamation mark on it or not?

~To download drivers and specific software;

Always get your drivers from the manufacturer of your Laptop, Notebook or Desktop.

If you were to log on to the acer.com web site, usually one is able to download if available, by model number, All available Driver downloads as required.

If the driver is not available, perhaps your manufacturer does not support the OS you are installing.

This is the best way of ensuring up to date drivers for your system and they are free of charge!

There are no XP drivers to be found with Microsoft as XP is no longer supported.

Some manufacturers may have a limited number of Drivers still listed.

Windows7 however, will run in XP compatible mode if you install that part of the programme. (Win7 Ultimate)

I hope this helps.
