Is there anything changed on the wireless router? You may need to contact the one who is in charge of the router. Or, you can check the network connection settings and figure out whether you are connected to another wireless network now. Sometimes it is automatically detected by your computer that one wireless network is not available and another one in the list is working so it will switch over.

Not connecting to the internet


Router ?

Problems authenticating a router in a computer is a common problem when installing a router or if your internet service gets disrupted. It is easy to solve and only requires a few steps to fix. A router forwards data from a computer to a computer network. The network can be between multiple computers, such as one would need in an office. The network can also, and more usually in households, used for connecting to the internet. Open "System Preferences" in the Applications folder in Finder. Open "Network" under "Internet and Wireless." Click "Advanced" and select "TCP/IP." Select "Renew DHCP License" and click ok. Attempt to connect to the internet. If the internet is still not connecting, restart the router and try the steps again. b> For non-Macs b> Open "Wireless Network Connection" from the wireless tab at the bottom of the screen. Select "Change Advanced Settings." Choose the "Wireless Networks" tab. Choose the wireless network you want to connect to and select the "Properties" button. Under the "Association" tab, make sure the Network Authentication has the proper security level chosen. Enter your network key if your security code is anything other than "Open" or "Shared." Select OK and try to connect. Go Back to "Wireless Networks" tab -> "Properties" and click on "Authentication" tab and un-select the "Enable authentication for the network" selection if the network key is still not authenticating the router. Select OK and try to connect.
Hope this helps.

Network Key (WEP, WPA, WPA2 Encryption key)To connectyour computer to a wireless router, you click the Refresh networklist, then Choose your wireless network and then click Connectto your secured Wireless Network, it will asks for a Network Keybefore allowing you to connect into your wireless network. This NetworkKey is either the WEP, or WPA or WPA2 Encryption key that is used toconfigure the Wireless Router. The Passphrase is an alternate way tosetup the Encryption key.
When you are requested for a Network Key, you can just enter the Passphrasethat was used to configure the Encryption key in the wireless router.http://www.fixya.com/support/r5270415-network_password_network_addressFor information on securing your wireless network,configuring the wireless router and configuring the wireless card in thelaptop/computer, please click on this link and follow my instructions :-http://www.fixya.com/support/r3559128-wireless_router_security

Dell vostro a860 won't connect to internet


Why not? Do you have the wireless turned on? Did you put the correct password in?


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 put the wrong password in, it will never connect. it will keep trying to connect but never will.

Authentication


That means you probably don't have the password or the Authentication Type set correctly.

For Windows XP below:
Click Start/Control Panel/Network Connections then Right Click on the Wireless Network Connection and select Properties. When the Properties window open click the Wireless Networks tab. Click on the SSID for your wireless network that you connect to and the Properties window will open. You can change the Authentication Type to match the type set in your wireless router and you can also change your password or Network Key to make sure you have it in correctly.

For Windows Vista below:

Click Start/Control Panel/Network and Sharing Center then look to the left of the open window and click Manage Wireless Networks. Find the SSID of the network that you connect to and double click it. When the window opens click the Security tab to change the Security Type (which is the Authentication), The Encryption Type and the Network Security Key (which is the password).

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

I have a medion laptop that wont connect to the wireless router or the ethernet?


What Operating System?

Try connecting to another secured network and when the key comes up just type anything since you won't know it. Then go back and try connecting to yours. Hopefully it will allow you to put the key in again.

Go to network settings and look at the wireless connection. Highlight your network and click properties. See if it will let you put the key in there. Also look at the Authentication Type, you may have the wrong authentication type (WEP, WPA, WPA2). You can check to see which type the laptop that you say connects successfully has, then make sure you use the same Authentication Type.

Wireless adapter disconnecting and reconnecting


Try these first:

change channels to 1-6-or 11. Make sure you change all of your wireless computers.


check is to make sure you are NOT using "IEEE 802.1x authentication for this network."

You can find at setting under "Wireless Network Connection1.gif Properties" and then under "Authentication" tab of your network properties.

This particular authentication method is periodically logging you off the network and re-authenticating.

Check the adapter in device manager to make sure that windows is not shutting the adapter down to save power.

Cordless phones and wireless ethernet cards use overlapping frequencies.As a test, you can unplug the AC cords from all the cordless phones in the area and see if it helps.

Are you using the VISTA adapter driver on the disconnecting computer?
