Q: Basic Wireless Troubleshooting
A:
Wireless Troubleshooting
The following steps will help determine if the wireless card in the system is functioning properly.
IMPORTANT:
Please go through all the troubleshooting steps. If the wireless card is functioning properly, please check the network configuration. Acer America can not assist with configuring the network.
Before you start:

• Make sure there is a wireless router or wireless access point.
• The wireless router/access point is plugged in.
• Refer to the owners manual to ensure the wireless adapter is on (you can turn the wireless card on and off by pressing a clear button)
• Contact the internet service provider to make sure ther account is active and the network is connected in a way that supports their configuration.

If the computer was working properly at an earlier time:
If the laptop was working fine, do a System Restore which rolls the system back to the last known working configuration. System Restore is located in System Tools under Accessories. Here is a link to explain the use of this feature:

To find the wireless network:
1. Click on Start then click on "Control Panel."
2. In the Control Panel window, click on "Network and Internet Connections."

3. In the "Network and Internet Connections" window, click on "Network Connections."

4. Once in Network Connections, right-click on the wireless connection then select "View available wireless networks"
5. If the wireless network is a secured network, please refer to the manual of the wireless router to make it unsecured for the purpose of testing the wireless network.
NOTE: Acer does not recommend leaving a wireless network unsecured and is not responsible for data accessed due to unsecured wireless networks.
6. If the wireless network is listed, the wireless adapter is functioning properly. If unable to connect to the wireless router, go through "Before you start" at the beginning of this article.

may be the connection you are trying to establish must have their server down....

If it is showing that it is "Disconnected" that simply means you are not connected to a wireless network. To connect to a wireless network simply double click on the wireless icon by the clock (bottom right side, looks like a computer monitor with waves) and select the wireless network you wish to connect to.

Secured Wireless is better than a unsecured one. Configuring a secured wireless network easy.
· First Check it the Wireless is turned on in the modem.
You must see the wireless light glow on.
Wireless LAN (WLAN) should be Enabled before configuring the wireless network
· To make sure, if the WLAN is enabled you can check the WLAN light glow.
· If it is off, then you can be sure that WLAN is disabled.

Are you using the Dell utility to connect to networks ? Try setting the network you want to connect to as your "Preferred" network in your wireless utility on your laptop. Also, try moving the network to the top of the list. Doing this might set it as your "Preferred" network.

because at a time both wirless and lan wont work so any one should be connected other wise whether u turned off the wirless lan button

Atheros AR5007EG adapter only WEP compatible. Wireless networks using WPA(2), or anything else won't work. If network is unsecured, it should connect.

Hi MistiShay,

You did mention that it was working fine for several weeks suddenly your wireless computers stopped functioning and your getting a message that the security key in incorrect. This only means that its either your entering the wrong encryption key or someone changed the previous security key to something else. By the way what type of wireless security did you configured on the router initially was it WEP or WPA, if its WEP(64 or 128 bit) and your using a bulit-in wireless adapter on your laptop you need the default WEP key because the passphrase only works with a Netgear WLAN Utility.

Know if your having difficulties accessing the setup page of the router you may need to check on your browser settings, turn off the pop up blocker and firewall temporarily, also try another computer. Now if all fails you may need to press that reset button on your router and set it up again.

In your laptop, when you plug the lan cable,
the led should blink.
if not blinking, you should check the router.

make sure that your wireless network card works.go to the settings of your router and set: wireless network mode:802.11b(or what your car supports) wireless network name:name Wireless SSID Broadcast:enabled Security Mode:wep wep key:write something create a new connection to your laptop with the above settings
