View Full Version : Wireless Card not detecting

17-10-2011, 07:19 PM
Hi there,

Trying to sort a wee problem out for a friend.....

They have an Acer Aspire 5520 laptop with Vista 32.

The only problem is the wireless internet connection, which was working fine until the other night.

I've had a look at it, and the computer doesn't detect the wireless card at all.

It's not in Device Manager at all.

I have updated the laptops chipset drivers, have checked bios etc.

I have opened the laptop and the card is seated in there just fine.

Any ideas? Is this a dead card, or something else?

I have sometimes had the same problem with my Asus Eeee701. To fix it I shut it down, remove the charger, remove the battery, then hold the start (power on) button down for 30 seconds. Refit the battery and then 'power on'. Don't ask me why, but it works. May not work on the Aspire.

Thanks for the idea....but no luck.

This one really has me beat. The card must be dead, eh?

Possibly - best way to check would be to use some sort of boot disk and seeing if it detects the network card.

Replacing it shouldn't be too expensive though.

Have you turned it off?

17-10-2011, 09:35 PM
Turned the computer off? Yep.

No! Have you disabled the wireless by turning that function off?

The laptop has a wireless on/off button. Pressing the button brings up a message "no wireless device" down the bottom of the screen, and makes no difference in the Device Manager.

I have taken the card out and reseated it to make sure it was inserted correctly.

I have tried everything...I guess the card must be dead?

Internal (built in) wireless card or some sort of USB device ??

It's an internal card.

It's an Atheros AR5007EG card.

Here's a weird update.

I chucked SIS Sandra on there to see if I could see the card through that software.

The card is visible (under network devices) in Sandra, but is not operational.

How the hell am I going to get this thing to make up?

As suggested earlier, get a live linux boot disk and try that and see if the wireless works, that'll tell you if it's hardware or software related.

I have booting up with an Ubuntu Live CD, and still no wireless capability in sight.

New card?

18-10-2011, 05:20 PM
Does it show up with "lspci | grep -i wireless"?

18-10-2011, 07:04 PM
No, still no sign of it in Terminal.

18-10-2011, 09:14 PM
Sounding poked ...
Do you have another machine to try it in?

I haven't got another laptop here....

I have bought a replacement part for them....will see how that goes?

Have the same problem with a Atheros ar5007G on a desktop, it gets reconised when it feels like it

20-10-2011, 05:15 PM

I have replaced the card with a new one....still no dice.


20-10-2011, 07:44 PM
Does the card slot look clean?

20-10-2011, 08:40 PM
Yeah, it's not bad at all.

I mean, it's looks just like a 2-3 year old laptop should. No obvious problems there.

Have you reset it with no power and the battery removed? Hold the power-on button down for 5 seconds.

sorry irrelevant post
