How do I set up the security system for my wireless router?

Hello.
- This error occurs when the wireless security that you set on the wireless laptop does not match the wireless security on the router.

• If the wireless router's security setting is WPA but on the laptop you used WEP for the wireless security, that's when a mismatch occurs.
  

- What you can do to resolve the problem is to delete the wireless profile you created on the laptop. After that, let the laptop search for wireless connection available, select the correct wireless settings and it should connect.
--For example the operating system of your computer is Vista, in order to remove the wireless profile you created and reconnect to the wireless router, do the following instructions:- Go to Start>Control Panel>Network and Internet> Network and Sharing Center- Click on Manage Wireless Networks on the left panel. Delete the wireless profile then Search for available wireless networks again. Type the correct wireless security settings on your laptop
-- If you would like to know what wireless security has been setup on the router, connect the laptop or use a desktop which is wired to the router then access the router setup page by typing http://www.routerlogin.net or 192.168.1.1 in the address field of your browser and then press Enter. Enter admin for the router user name and your password (or the default, password).

--After logging in. In the main menu on the left, click on Wireless Settings, from there you can check the wireless security or you can setup wireless security from there if you haven't done so.

Hope this helps. Have a nice day. Don't forget to vote if you find this guide helpful. Thanks.

By secure system i only see two loopholes, WAN and Wireless, im assuming you know how to log in to the management console, try setting wireless security to WPA Personal and choose a long passphrase, change router password and enable intrusion detaection capabilities under firewall settings, basically thats it, Hope this works...

How to find security key
Your wireless network must be secured
You will need to check the wireless settings of the router.
Is there any computer online using the router.
check the IP address on that computer.
If yes then you can open the router set up page on that computer.
router set up page is the page where you can check all the router settings.

Set wireless security to one of the options available. Also, set the router system ID, and change router login password, (record it somewhere, like on the actual router) change the wireless channel to 11 to avoid conflict with landline wireless handsets.
There are higher security settings, but wireless access password is pretty effective.

I have the same router and the Cisco Systems is lit up with a white light behind it and it's working fine.

You need to ask whoever set up the wireless router what the security key is. Apparently, who ever setup the router encrypted the wireless network. Any computer wanting access to the wireless network must have the security key initially entered in for access. If it is your own router, you can access the router and change the security key your self in the wireless setup portion.

To secure the wireless network or to change any settings on the router you will need to access the router set up interface.
Open the set up interface of the router . Make sure that your computer will be connected to the router with the Ethernet cable.

Once you open the set up page of the router , you will find the place to change the wireless settings of the router. In case of Linksys wireless router , you will see the Wireless Tab at the top.

SSID : It is the name of the wireless network. This name will be shown on your wireless computer or the wireless device so that you can identify your own wireless network. All the routers come with their factory default settings. For example , the Linksys router will come with the Linksys network name.
It will be better to change the wireless network name.


Wireless Security

Change the security mode to WEP. This security type is supported by all the operating system. When change the security mode to WEP, you will find the Network key box to type the network key. Do not type anything in the Passphrase box. Type your network key in the Key 1 Box. If you set the encryption to 65 bits, your network key will be 10 digit hexadecimal number. that means you can use the combination of 0,1,2,3,4,5,6,7,8,9 and letters a,b,c,d,e,f only. remember it should be exactly 10.
If you set the Encryption to 128 bit, your network key will be the combination of 26 digits. You will need to remember the network key.

WPA

This is one of the most secured type of encryption.
Open the set up interface of the router. Change the wireless security mode to WPA personal. You will find the passphrase box. in this box you can type any password for your wireless network. The password should be the combination of number and letters and it should be 8 or more than 8 characters.
This security type is supported by WINDOWS XP SP2 and above Operating system.

WPA2
This is one of the highly secured type of encryption.
Open the set up interface of the router. Change the wireless security mode to WPA personal. You will find the passphrase box.In this box you can type any password for your wireless network. The password should be the combination of number and letters and it should be 8 or more than 8 characters. Keep the Algorithm to TKIP.
This security type is supported by WINDOWS VISTA and above.

on connecting your laptop wirelessly, it is best if you set the router to have wireless security first.

accessing the router's setup page:

open IE, then type http://192.168.1.1 on your address bar, it will ask you for a username and password, thats both admin (these steps will depend if you have changed the settings on the router)

once opened, go to the wireless tab, change your Wireless Network Name (SSID) to something esle instead of Linskys, like your name perhaps. then set the channel to 11ghz and hit save settings.

now look for a Wireless Security SUBTAB, enable to wireless security, under security mode select WPA-Personal (PSK) set your algorithm to TKIP and make up a password on the blank space that says Passphrase / Pre Shared Key , that will be you wireless security code. now hit save settings.

in connecting your wireless laptop, make sure the wireless adapter on the device is enabled and it will automatically locate the wireless network and wil ask you for the security code, once you place it, you will get connection.
