Wireless association failed due unknown reason

go to www.facebook.com and log in from there

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

have you reset it? to its factory default

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,

There could be many reasons for your problem.
1. If you use proxy server, make sure the server and the service are up and running
2. If you use proxy server check the Internet options and look for the correct values in the required fields.
3. If you use wireless router check the connection to the router.
4. If you use router check the network configurations. Many of the routers have internet connection test. So login localy to the router interface and check the connection.
5. If everything above is correct try pinging a website from cmd. Open command prompt Start->Run->cmd. Write the command "ping www.google.com" (without the quotes). If you have ping look for application that blocks the http traffic on port 80. If the result is "Request timed out" try to ping 209.85.148.104. If you cannot ping any site or computer outside your network, then you have to call your provider.

try to check your pc IP address may it not same setting with the wireless network, set it automatic may it work

You may want to disable the built-in utility of the network adapter and let the wireless zero configuration of Windows take up the task of managing the wireless network.
 

You need to get the wireless authentication details from the library's front desk to configure your wireless connection. They should be able to help you.

You may have conflicts with older driver and newer one, you will need to uninstal the belkin drivers and start again, making sure you install Vista drivers, the cdrom may not have them on, only XP

I finally discovered the problem. I have a Linksys wireless
router, so when I tried to log on with my iTouch, I got the
message "Unable to join network "my network name" when
I typed in my password. One day, after many trys, I tried
typing in the network security key for my router, and Voila,
it worked. For some unknown reason (to me), the iTouch
recognizes the the network security key as the password.
