I tried to change from WEP to WPA but the password will not go through. It makes it an unsecure line for wireless. What am I doing wrong?


The Short Answer:
Your password might not meet criteria. It also depends on whether you use a custom encryption key. If so, then you either need to create a 10-digit or 26-digit hexadecimal number (numbers 0-9 & letters a-f) depending on whether you use 64 or 128-bit encryption.

The Long Answer:
A WPA password must be between 8-63 characters long, and must only contain ASCII printable characters.
The 2Wire User Guide for the 2700 states the following:
"You can customize the following wireless settings in the Wireless Security panel.
1. From the Authentication pull-down menu, select an authentication setting: WEP-Open, WEP-Shared, or WPA-PSK.
Note: WPA-PSK authentication is supported only on HG model gateways.
Open authentication allows users to configure their wireless adapter as either Open or Shared; in either case an encryption key is required. Shared authentication allows users to configure their wireless adapter for Shared authentication, which requires an encryption key. WPA-PSK requires that users configure their wireless adapter using TKIP.
2. To use the encryption key that came with your gateway, click the Use default encryption key radio button.
To create a custom encryption key, click the Use custom encryption key radio button. If you select Use custom encryption key, you can define a 64-bit or 128-bit encryption key. For 64-bit encryption, enter a 10-digit hexadecimal number. For 128-bit encryption, enter a 26-digit hexadecimal number. A hexadecimal number uses the characters 0-9, a-f, or A-F.
3. Click SAVE"

1. Log into the router. To do this you will need to open your web browser and enter http://192.168.0.1

418789b.png
2. You will need to log in to the router. The Default Username and Password:
User Login
Username: cusadmin.
Password: password
fdacc91.png
3. Next click on [WIRELESS] link on the Side Navigation bar.

4. Select [WEP] from the [SecurityMode] drop-down menu.

e29ce8a.png
You can choose between standard 64-bit or 12b-bit encryption keys. Below are the configuration options for 64-bit WEP. A passphrase or a manual key can be used

NOTE: To enter a manual WEP key you will need to enter hexadecimal values (A-F and 0-9). Example: 64-bit hexadecimal keys are exactly 10 characters in length. (123654ACDE is a valid strong of 10 characters for 64-bit encryption).

f803ad7.png
To automatically generate a 64-bit WEP key, enter in a Passphrase (keyword- ex. homegateway). And click the [Generate Keys] option. Once you do this, the Gateway will dynamically generate 4 keys. Simply configure the Default Key to the one key that you will be using across your network.

5. Select the Open System, Shared Key or Automatic from the [Authentication] drop-down menu. Note in most cases you want it set to Automatic.

44a4e82.png
For more security, you can use 128-bit WEP encryption. To use this mode, select the [128 bit (26 hex digits)] from theWEP Key Length drop-down menu option and the configuration section will be displayed. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a strong in HEX (hexadecimal- using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. You can manually enter in the 26-digit hexadecimal key.

Example: 128-bit hexadecimal keys are exactly 26 characters in length. ( 234FEDCBA12340013333389319 is a valid string of 26 characters for 128-bit encryption).

31fa92b.png
NOTE: If you are having a difficult time getting the wireless connection up after enabling WEP- Please confirm that you have configured the SAME WEP key on both the Gateway and Client card.

  4. Change your wireless settings and use the following information if you want to change to a custom WEP key.

    64-bit hexadecimal keys are exactly 10 characters in length. (For example, 123456789A is a valid string of 10 characters for 64-bit encryption.)

    128-bit hexadecimal keys are exactly 26 characters in length. (For example, 456FBCDF123400144445271730 is a valid string of 26 characters for 128-bit encryption.)

    64-bit ASCII keys are exactly 5 characters in length. (For example, GMODE is a valid string of 5 characters for 64-bit encryption)

    128-bit ASCII keys are exactly 13 characters in length (For example, 2008SUNSSWIN1 is a valid string of 13 characters for 128-bit encryption.)

How do I install my WEP number


go to 192.168.1.1 If you have already configured the router for internet access, then just click on "configuration" otherwise, go through the steps to configure it according to your ISP's instructions, then click on configuration. then wireless. Then go down to privacy settings.

Pick which authentication type to use ( I recomened open)
Then pick the highest encyption meathod that all of your wireless devices are capable of. 64-bit, 128-bit or 256-bit.

Most devices use 64 and 128 bit, but if all of your devices use 256, then use it. Then create a wireless key to use.
If key select is selected, the WEP Key is treated as a string of text characters, and the number of characters must be either 5 (for 64-bit encryption) or 13 (for 128-bit encryption) or 29 (for 256-bit encryption).

If not selected, the WEP key is treated as a string of hexadecimal characters, and the number of characters must be either 10 (for 64-bit encryption), 26 (for 128-bit encryption), or 58 (for 256-bit encryption). The only allowable hexadecimal characters are 0-9 and A-F. (My hint is to use hexadecimal, it is eaiser)

If you would like to create a new WEP key go to this site (http://www.powerdog.com/wepkey.cgi) and type in a passphrase and click generate. it will generate 4 64-bit keys and 1 128-bit key.

choose the best bit 64 or 128 bit, then copy and paste it into the correct key box(es)

When you changed the WEP encryption from 64 bit to a stronger 128 bit encryption the encryption code gets changed and when you changes it back to 64 bit the new 64 bit encryption code will be different to the old 64 bit encryption code, that is why your laptops cannot connect to the router. The laptop wireless card needs to be configured with the new 64 bit encryption code before it can connect to the wireless router.
I suggest you configure the wireless router with WPA or WPA2 encryption, this is a much stronger encryption method than the old WEP encryption.

Not able to connect the sons Nitendo DSi to the internet. They are asking for the WEP Key but on my home hub there is only a WPA Key. BT have told me to connect to you to ask for support.


If your using WPA and your Nintendo DS only supports WEP Encryption theres no way you can connect it to the internet. WEP encryption is different from WPA.

WEP key uses hexadecimal - using characters 0-9, A-F or ASCII format. The ASCII format is easier to remember. The ASCII string is converted to HEX over the network.

Example of WEP key encryption are:

*64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for 64-bit encryption.)
*128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.)
*64-bit ASCII keys are exactly 5 characters in length (DMODE is a valid string of 5 characters for 64-bit encryption.)
*128-bit ASCII keys are exactly 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption.)

WPA Key is entered as a pass phrase between 8 to 63 alphanumeric characters in the ASCII format at both ends of the wireless connection. Although PSK accepts a minimum of eight characters, for proper security, it is a good idea to use ample length and should not use a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client.

To resolved the issue you have an option to change the WirelessSettings on your router to WEP instead of WPA since WEP is also a secured netwrok. however you need to keep in mind that if you change the encryption you need to configure all othere device connected to the router via WPA and change the settings to WEP.

I downloaded Windows 7 and my wireless laptop won't connect to my 2wire. Where can I get new security key code or info get my laptop to work?


Hey pkkern,
.
Your default 10 digit security is located on the bottom of your router.
.
If you want to change it or for some reason your default key is no longer working we will have to get into the routers configuration homepage.
.
To access this open up your Internet browser and write in this address, (which is your routers address) 192.168.1.254.
.
If your routers homepage does NOT open up check to make sure you have no software firewalls
.
Click the Home Networking tab at the top of the 2Wire Home page.
.
Click EDIT SETTINGS located on the right panel (Status at a Glance) under the Wireless Settings heading.
.
You will see a wireless network security section, use the following information to select a custom wep-key.
.
Change your wireless settings and use the following information if you want to change to a custom WEP key. 64-bit hexadecimal keys are exactly 10 characters in length. (For example, 123456789A is a valid string of 10 characters for 64-bit encryption.)
128-bit hexadecimal keys are exactly 26 characters in length. (For example, 456FBCDF123400144445271730 is a valid string of 26 characters for 128-bit encryption.)

WEP Encryption


It is recommended to enable encryption on your wireless router before your wireless network adapters. Please establish wireless connectivity before enabling encryption. Note: Your network will slow down and wireless signal may degrade when enabling encryption due to the added overhead. Step 1 Log into the web configuration of the router by opening up a web browser and typing in the IP address of the router (192.168.0.1). Step 2 Enter your username (admin) and your password (blank by default). Click OK . Click the Home tab and click the Wireless button on the left hand side of the screen. Step 3 Select Enable next to the WEP radio buttons. For WEP encryption select 64, 128, or 256-bit encryption. For the Key type select HEX. If you have an option for Authentication type, select Shared Key. Step 4 Select Key 1. Enter a Hex encryption key that you make up. The length of the encryption key will depend on what you selected under WEP Encryption. 64-bit encryption 10 characters 128-bit encryption 26 characters 256-bit encryption 58 characters (available on DI-614+ only) The encryption key is HEX, meaning 0-9 and A-F are valid characters. For example, A4583DFF1A (64-bit HEX key). Step 5 Click on the Apply button then click on the Continue button to save your settings. Note: If using non-D-Link adapters, please refer to the manufacturer´s documentation on enabling encryption.
