The second possibility is to set the local security on your network.

From the wikipedia page:
Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is a notoriously weak security standard. The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1999 which was outdated in 2003 by WPA or Wi-Fi Protected Access. WPA was a quick alternative to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device which encrypts the network with a 256 bit key; the longer key length improves security over WEP.

Wireless security

Log in to your router and find the wireless security section. Set up the security model that best suits your needs and then set up your wireless network card with the same information.

Hi Paul!


Link DSL G604T User Manual Page 22 of 26

Here is the link to the manual, hope it will help.

NOTE: Image may vary depending on the type of router and computer you are using.
To setup your router's wireless security settings:
i. Accessing the web-based setup page
ii. Setting-Up the Wireless Security
Accessing the web-based setup page

Step 1:
Access the router's web-based setup page by opening a web browser. On the Address bar, enter your router's local IP address then press [Enter].

NOTE: The default IP Address of Linksys routers is "192.168.1.1". For instructions on accessing the web-based setup page using a Mac computer, click here.

Step 2:
When the login prompt appears, enter your router's Username and Password.

NOTE: The default password is "admin" and the Username field is left blank. If you have set a password before but forgot it, you need to reset the device. For instructions on how to reset a Linksys router, click here.

Step 3:
On the Setup page, click the Wireless > Wireless Security.

NOTE: If some of the tabs are missing in the web-based setup page, upgrade the firmware of your router. For instructions, click here. You can also set the wireless security of your Linksys E-Series routers with Cisco Connect. To learn how, click here.

On the Wireless Security sub-tab, there are various wireless security options that you can choose from.

However, as mentioned earlier, the three most commonly used security modes are WEP, WPA Personal (or WPA Pre-Shared Key), and WPA2 Personal. The instructions below will show you how to set up the following security modes. On the other hand, the WPA2/WPA Enterprise Mixed Mode, WPA Enterprise, WPA2 Enterprise, and RADIUS security modes will only work if the router is connected to a RADIUS server.
Setting-Up the Wireless Security

Wired Equivalent Privacy (WEP)

WEP can be a 64-bit key with 10 hexadecimal digits or a 128-bit key with 26 hexadecimal digits. This encryption will prevent other users from connecting to your wireless network. It will also protect your wireless transmissions from being accessed by other users.

NOTE: In case the screen on your router's web-based setup page looks different, click here.

Step 1:
On Security Mode, select WEP.

Step 2:
Under WEP Encryption, select 40 / 64-bit (10 hex digits) and enter a unique word in the Passphrase field.

NOTE: The 128-bit key uses a higher level of encryption compared to the 64 bit WEP. It uses a 104 bit (26 Hex Character).

Step 3:
Click the Generate button and copy the string of letters and numbers displayed in the space provided for Key 1. The Key 1 contains the wireless password.

NOTE: You can also create your own Wireless Password (Key 1) given that it is in hexadecimal format. The hexadecimal system consists of the characters 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F. You can only choose 10 characters (in any given order) from that set.

Step 4:
Click .

Wi-Fi Protected Access (WPA)

Wi-Fi Protected Access (WPA) is a Wi-Fi standard designed to improve the security features of WEP. WPA is stronger than WEP encryption. PSK and PSK2, the two types of WPA, give you a choice between two encryption methods: the Temporal Key Integrity Protocol (TKIP), which incorporates Message Integrity Code (MIC) to provide protection against hackers, and Advanced Encryption System (AES), which utilizes a symmetric 128-Bit block data encryption.

NOTE: For older versions of Linksys routers, WPA Personal is also referred to as WPA Pre-Shared Key. Refer to the image below for an example.

To set up WPA Personal on a Linksys router, follow the steps below:

Step 1:
On Security Mode, select WPA Personal.

NOTE: If you are unable to find the WPA Personal or WPA2 Personal in the list of choices for the Security Mode then you might need to upgrade the firmware of your router to its latest version. Upgrading the firmware can fix the bugs of the previous version and update its other features.

Step 2:
Enter your Passphrase.

NOTE: The Passphrase must consist of at least eight characters and is case-sensitive.

Step 3:

HI,

Its the problem witht the Firmware of the router, ie error in the software installed inside the router..

Try updating the latest firmware from the manufacturer website..This should solve your issue..

Please rate this solution if this solves your issue, or leave me comment ill help further

you want to put a password on wpa security...
here's what you do, actually you are going to open the firmware of your Wireless Router.
Open Internet Explorer, at the "search engine" just type the Gateway Address (192.168.x.x) then ENTER. After that will asking for Login: admin Password: admin __ this time your on the firmware of the Router. This time will appear and select for putting a password on wpa security. Hope this might you the steps. Good luck!

Let me clarify to make sure I understand the problem: You set up your wireless router with a WPA 20 digit wireless key. You have a laptop which cannot connect with the 20 digit key specified. If I have misunderstood your issue, please let me know.

The first step always in this situation is to check and re-check your wireless key and make sure that you are entering it correctly. I will assume that you've already done this.

From there, you have 3 options to rectify the issue:
1) Set up the wireless router with a WEP wireless key.
2) Download a firmware update for your wireless adapter in your notebook to allow it to use WPA encryption.
3) Purchase a PCMCIA wireless card for your notebook that works with WPA encryption.

Please let me know if I can help any further.

Hope this helps. Please take a moment to rate this solution. Thanks.

If you dont know your wpa network key try to reconfigure your wireless network again.

Access the configuration page of your router.
>Type on the address bar 192.168.0.1
>On login type Admin leave password blank. if you set up a password or the login page use that one.
>Once inside the Dlink Page
>Clik Setup and on the left side click wireless setting.
>If given the option to click on manaul wireless connection setup click on it.
>Once you have the wireles window
>try to change the network name to a new one and scroll down
>Under security choose WPA security (enhanced)
>Scroll down and under the Passphrase type in your new network password or security key and confirm it.
>Click on Save Settings
>If it asks you to reboot then reboot it, if not, its ok.

Well if you updated the firmware and your still having issues contact dlink for a possible replacement it sounds like the hardware could be bad or you can try uploading same firmware by crash reseting router and uploading latest firmware again.

is the PC connection you're able to maintain once upgraded to WPA a PC that is physically connected to the router? if so, that would make sense because WPA (and WEP for that matter) are only wireless security protocols and have no protections for hard-wired connections.

In order to convert your system to WPA security, you must first make sure all of your hardware is WPA compatible (that isWPA Drivers are available for it).

For your PC wireless connection, if you're running Windows XP you can go to the microsoft website and download the WPA client. It is available in the Microsoft Knowledge Base Article 815485. install the update and reboot. you will then be able to enable WPA security on your client.

Then you'll possibly need to update the drivers for your hardware for WPA support (router, wireless NIC, etc) if they did not already come enabled.

next you get to configure the router for WPA. you'll want to make sure you're set to WPA with preshared keys (no authentication server required), use TKIP as the algorhythm, and leave group key renewal at it's default value. and of course Select a key that is not likely to be guessed. write the key down as you'll need to configure your NIC using it.

to configure your NIC, once you're in the configuration menu select WPA-PSK for your authentication, TKIP for the encryption mode, in data encryption set it to TKIP, and in the network key put the key you selected earlier.

At this point you should be able to access your wireless router (or other access point). These instructions were kind of generic since i do not have the specific router you're using available to me, but the settings i discussed should be pretty universal when it comes to WPA security.
