I don't remember my network key,so I cannot use it

It will be written on a label somewhere on your wireless router/access point, which is in most cases the box provided to you by your internet provider to let you access the internet.

You'll most likely be prompted for a password as well, this is also found on the same sticker.

Login in using your browser and go to the wireless settings and set-up a wireless password/key. Remember the key because each device will now need it to connect. You can also turn OFF Broadcast SSID and your network name will not be shown on anyone's device. You must remember the network name when using this method.

Does it show you any wireless networks (routers) when you select View Available Wireless Networks? If not maybe you don't have the wireless switch on the laptop turned on.

Maybe you don't have your wireless turned on. Look on both sides and in front for the Wireless Switch and turn it on.

Also once the wireless switch is turned on there are keystrokes that can toggle the wireless on or off. Normally you would Press and Hold the FN function key located at the lower left of the keyboard, then hit the correct F1 thru F12 key that toggles the wireless. The correct F1 thru F12 key to hit will have the wireless signal icon )))) on it. Or it might have the icon of a tower with the wireless signal icon )))). Normally the screen will display Wireless On or Wireless Off when you toggle the wireless.

If you can see other wireless networks but not your own, then just go near your router with the laptop and see if it detects it. If not, you might not have the router configured for wireless. Can other laptops in the house see your wireless network? If so, then it is configured correctly.

There are two ways on which you can get on your wireless network. One way is to use the wireless software that came with the wireless adapter. The other way is to allow windows to control the wireless called (Zero Config). Whichever one you are using, try switching to the other to see if it picks up your wireless network. If you are using the software that came with the adapter when you open it you will see an option somewhere that will allow you to let windows control the wireless (zero config). Select it and try seeing it windows picks up the wireless signal from your router. Likewise if you are using windows (zero config) switch to the software that came with the adapter and look through it for an option that will say something like "Use this tool to manage the wireless". Select it and see if your network is picked up.

If you still don't see any wireless networks and the router is ok I would say your wireless card inside the laptop is not working properly. Turn the laptop off, remove the power cord, remove the battery then remove the cover that houses the wireless card on the bottom of the laptop. Remove the two antennas (black and white cable) from the wireless card (remember where they go). Then remove the screws if any so that you can remove the wireless card from the slot. Wait 30 seconds, then put it all back together and see if just reseating the wireless card fixes your problem. Sometimes the wireless card might be located under the keyboard and palmrest.

AuthenticationThat means you probably don't have the password or theAuthentication Type set correctly.

For Windows XP below:

Click on the SSID for your wirelessnetwork that you connect to and the Properties window will open. You canchange the Authentication Type to match the type set in your wireless routerand you can also change your password or Network Key to make sure you have itin correctly.

For Windows Vista below:
Click Start/Control Panel/Network and Sharing Center then look to the left ofthe open window and click Manage Wireless Networks. Find the SSID of thenetwork that you connect to and double click it. When the window opensclick the Security tab to change the Security Type (which is theAuthentication), The Encryption Type and the Network Security Key (which is thepassword).

For Windows 7 below:
Click Start/Control Panel/Network and Internet/Network and Sharing Center thenlook to the left and select Manage Wireless Networks. Find the SSID of thenetwork that you connect to and double click it. When the window opensclick the Security tab to change the Security Type (which is theAuthentication), The Encryption Type and the Network Security Key (which is thepassword).

You will need to open the setup page of the router and check the wireless settings of the network.

Read Wireless network key WEP WPA

Try the following procedure on a computer that's directly connected to one of the router ports with an ethernet cable. This procedure will not work if you're connected wirelessly. Open a web browser, such as Internet Explorer, and type in http:192.168.1.1. A window should pop up asking for a user name and a password. Don't enter a user name and type admin for the password. Hit ok. The router setup screen should come up. Click on the Wireless tab and then the Wireless Security sub-tab. You should be able to see your present wireless network security key on this screen. You can also use this screen to change the key if you want.

If you want to make some changes first select the security mode you want to use. I believe WPA gives better security but I've had some trouble using it on older computers. I use WEP. I've been able to get this encryption scheme to work with all of my computers. Next select the type of encryption. I like 128 bit 26 hex digits. Next enter a pass phrase and hit generate. The pass phrase is like a password. It should now generate four 26 character keys made up of various letters and numbers. Write down the first key and make sure you've checked the 1 box for default transmit key. Save your setting and exit. You wireless network is now secure. If you try to connect to it using a wireless device you will be prompted for a security key. Depending on the operating system you're running, you may just be able to enter the pass phrase or you may need to enter the 26 character key you wrote down. You should only have to do this once for each of your wireless devices. After the first time they connect to the secured network they should automatically remember the security code. I hope this advice helps you out.

Your printer must have wireless capability. It is asking for your wireless security passphrase in order to join the wireless network. This passphrase is the key/phrase that you created when you setup your wireless network. You will need to login to your router and go to wireless setting section to find out what the passphrase is if you don't remember it. Thanks

Hi there!

It is possible that the Linksys wireless doesn't have any password/WEP key to connect that is why your phone can connect to it. You can't the other networks available if you don't have the password/WEP key. It has password enabled to prevent unauthorize connection to the wireless. I suggest you subscribe to your own wireless connection so you don't need to worry about connecting to any wireless network available.
