My wireless laptop cannot detect wireless networks..

Check the wireless router and high-speed modem.

If the two are not powered on, or if the Ethernet cable connected the two is not completely inserted into both connection ports, you are unable to access the Internet on the Acer Aspire One laptop computer.

Activate the wireless Internet connection on the laptop computer.

Right-click the wireless icon on the desktop, then choose "Enable" from the pop-up menu.

Without activating the wireless receiver on the Acer Aspire One, the laptop is unable to detect any wireless network.

Select the appropriate network you wish to connect to.

Your computer may be attempting to connect to a different Internet connection, preventing you from access the network you desire. Right-click the wireless icon, select "Search for available wireless networks," then choose the network you want to access.

Restart the computer.

The system may have booted and failed to detect the wireless receiver. Restarting the computer corrects this issue.

hope this helps

Hi,

Is the laptop detecting any wireless networks in the area? if yes then it means that the wireless card is ok if not make sure that the wireless is turned on on your laptop.

I the laptop detects wireless networks in the are then we should check the settings on your system or something that could be interfering with the wireless connection on your system,
what are the error/s when trying to connect wirelessly?

Tis can be multiple things regarding wireless, if the error is windows was unable to conenct to wireless evice then try recreating the wireless network on your laptop in network and sharing center if you have win7 on the laptop, network conenctions if you have XP.

I the laptop connects to the router but does not get internet acces then better check you routers network key if it is correct in your laptops settings, also check your IP address if it is correct if you IP starts with 169... then have a bad IP address on your laptop, go to the command prompt type ipconfig /release, then press enter, then type ipconfig /renew then enter to renew your ip address, hoping that the IP address changes it should begin with 192...

stupid question : is Wifi turned on ?
Go to your administration environment of your router ( typically : http://192.168.1.1 ) and check the config of the wireless settings

pc wireless adapter will work then if you have also another network like wireless router or another PC or Laptop with wireless adapter, if your going to use this wireless adapter network in pc to pc is you are going to setup by adhoc to adhoc connection, itself detect for sharing a network without any router needed, but if you do such simple network connection use wireless router, its definitely work easily. Aumatomaticall detect wireless router on your wireless adapter network.. Good luck!

try to setup again  wireless card's driver  if it doesnt work your wireless car is break down.
have a nice day and sorry for english.

1. First, you have to make sure that the Wi-Fi of your laptop is turned on.

2. Make sure that there's an available wireless network in your area so that you can test if the computer can detect any available network.

3. If you're running Win XP, right-click the wireless icon on your system tray and select "View available wireless networks"

4. If you can't detect any wireless network, right-click the wireless icon on your system tray and select Open Network Connections.

5. Right-click the Wireless Network Connection icon and make sure to enable it.

6. If it's already enabled, try to disable it and then re-enable it.

7. If you can't still detect any wireless network, try this:
- Click the Start > Run > type msconfig > hit Enter

8. Locate the Wireless Zero Configuration and click on it once.

9. Once it's highlighted, locate the Start button on the upper left hand corner of that screen.

10. After starting the Wireless Zero Configuration (WZC), try to detect the wireless network again.

first check for whether the wireless switch on laptop is turned on or not u have to keep it turned on .further install the drivers for wireless lan

Please make sure that the wireless antenna switch is on. Then enable the wireless feature using the hot key combination for your laptop (if available but need not be done since you were able to detect networks earlier). If you are using Vista, please click on Start-Connect to to see if your laptop is now able to detect networks.
If laptop is not able to detect any networks, please uninstall the wireless network adapter by going to Start - Control Panel - Classic View - Device Manager - Network Adapters - select the one for the  Wireless Network Adapter - properties - driver tab - uninstall - ok. Then please restart your laptop. Click on Start - Connect to  and see if your laptop is now able to detect networks.
If laptop is still not able to detect wireless networks, please click on Start - All Programs - Accessories - System Tools - System Restore then choose a restore point (date) which is a possible time when your laptop was able to detect wireless networks. Laptop will restart automatically and notify you if the restoration is completed. Try Start - Connect to. Hope it works this time. Thank you.


 

If it cannot find any networks, check to see if there is a wireless on/off switch on the computer - look carefully some are well hidden. The switch turns the antenna on and off but windows still detects the network adapter and thinks everything is ok.

Check the channel reception of your laptop wireless card or try changing the channel on your router.
