I have an Acer Extensa 5220 running an Atheros wireless connection. If I disable the connection through My Network Places then close the lid, when I reopen it, the connection no longer exists. Not only is the wireless connection not in  My Network Places but if I go to Device Manager it has completely disappeared there too. In Device Manager there is nothing else showing with a cross or a question mark.

I can try reinstalling the driver but it says there's not Atheros card present.

If I go back to factury default through Recovery Management (and reinstall everything!!) the Atheros wireless connection reappears so it's nothing physically wrong.

Check two things,
see if wireless is disbaled in BIOS

and if this is disabled, enable it
also
if this doesn' t fix the problem,

go to acer support select your model update BIOS.
http://support.acer-euro.com/drivers/notebook/ex_5220.html 

geneally you need to press DEL key on startup screen in order to get into BIOS.

please feel free to ask if any question arises in you mind

The wireless isn't listed anywhere in the BIOS. However I have tried setting the BIOS to manufacturer defaults and that doesn't help.

I've tried installing the latest Atheros driver from the Acer support site but it doesn't help. It says it can't see the card. However card comes back fine if you install factory setup so it's definitely there.
Out of interest loads of people complaining of something similar on Google. Gone through masses of options but just got it to work in this bizarre and very roundabout way:

I downloaded the latest Atheros driver from the Acer website - 7.6.0
Installed this using their Setup.exe
Went to Device Manager and the wireless adapter had appeared but with a question mark
I clicked on properties and found it thought it was using a previous driver 5.x.x
I right clicked and uninstalled the driver
I went to Add Or Remove Programs and found the Atheros 5.x.x driver there (!!!)
I uninstalled that
I rebooted
On startup I installed the 7.6.0 driver again
It worked.

OK, so not logical but these cards and/or their original drivers seem very dodgey.
