Can't find the wireless adapter in the hardware list. however the switch seems to be working and wlan red lights comes on, but thats it. Its been happening ever since i reinstalled my windows, i did download drivers form acer website but no use. please help

Have you download any software recently? Often times, this can alter things with your network, (irritating, yes I know), something like a new security program...... Try disabling the security and then try enabling it...... Hope this helps :)

PS: Remember after you are connected to enable your security program....

1. device manager (right click on my computer icon on desktop and select properties - select tab hardware - select device manager ) and check in the right pane for network adapters , under network adapters ull find the wireless name , check the status by double clicking on it .

2.go control panel -network connection (for xp ), network and sharing center - manage network connections on left (vista) , network and sharing centre - change adapter settings on left (win 7) and please check for wireless adapter status -says enable or disable

make sure both are enabled and then check with the wifi switch on your machine .

Check on Device Manager if it is working properly

Right-click My Computer-Properties-Hardware-Device Manager
Click on the plus sign beside Network Adapter and double-click your wireless card.
Check on the device status if it says it's working properly.
Try to disable-enable the adapter by right-clicking on it under the device manager window.
If it has a question mark, it is most likely driver issues so contact your wireless card manufacturer or PC manufacturer if the wireless card is built in.

1) Verify if Wi-Fi WLAN interface of your notebook is OK.
1a) Check whether HW switch is ON and the wireless system service is running.
1b) Switch on the WLAN Access Point (router) SSID broadcasting.
1c) Scan WLAN networks by the notebook. Can you see your home WLAN? If not, there is HW or SW problem in your wireless adapter probably. If WLAN is visible, continue by next steps.

3) Activate DHCP server in the router and set the dynamic IP assigning on WLAN notebook interface.
4) Select your home WLAN SSID in the list and try to connect.
5) Wait and check status. Is WLAN connected? Does obtain the notebook an IP address?

Hi There, since Acer do no release a wlan driver for Windows XP, you need to use the driver for Window Vista. If you do not have the driver for Windows Vista, you download it from here . After finish downloading, then un-zip the file. Now let's start to install the wlan drivers. Go to your "Start Menu", then "Settings", "Control Panel" then "System", system properties windows will be pop up. Then select "Hardware" tab, and then click on "Device Manager" button. You will then see "Device Manager" windows. Look for your "Network Adapter" and you will see your wlan network adapter with red cross mark.Right click your red crossed wlan adapter, then select "Update Driver"
You will prompted with "Hardware Update Wizard" then select on "No, not this time" radio button and click on "Next" button. On next windows, select "Install from a list or specific location (Advanced)" radio button and then select "Next" buttons.
Then another window will pop up, then select "Don't search, I will choose the driver to install", then click on "Next" button. Then you will come to this windows "Select Network Adapter", you will see you existing network adapter that do not working, then select "Have Disk", and browse to the location where you have unzip the driver. Then Select the appropriate driver for your laptop. Acer Aspire laptop 4720z come in 3 wlan varian, Intel chipset, broadcom, and Atheros and I don't know which one is on your laptop. Just try one by one if you are not sure, it's only 3 to choose from.
Hope my solution could help you out.

Hi car7924,

First, make sure that the wireless switch on the left side of the computer is turned on (this should make the WIFI light go on -- beneath the lower right corner of the screen). If it doesn't work, then try going to Start Menu > Control Panel > Network and Internet Connections > Network Connections.

You should see the Wireless Network Adapter in the window that comes up. If you don't, you need to download the driver for that adapter. The most common adapter in the D820 is the Dell 1390 WLAN MiniCard, and the driver for it can be downloaded at the following web address:

http://drivers.softpedia.com/get/Other-DRIVERS-TOOLS/Others/Dell-Latitude-D530-Wireless-1390-WLAN-MiniCard-Driver-A17.shtml

If, on the other hand, you do see the Wireless Network Adapter, but it says "Disabled" underneath the name, then right-click it and select "Enable." This should make it work.

I hope this helps - please let me know if I can be of any further assistance.

Kind regards,
H2H

If you have vista click the start button and in the start search type "hp wireless assistant". It should show up in your list while you type it. Click on it. Once the assistant box shows up, click on "properties". A "settings" box should show up. The main one you need here is "independant controls for installed wireless device". Check that box. The other ones are icons and indicators that you can check at your discretion. If in doubt, check them all. Hit the "apply" button. Then in the upper right hand side of the box hit the button that says "turn on". This should activate the device and if you have a light up indicator on your computer, it should change color or light up. That should do it. Kind of weird how it gets to that point.
