Windows XP Wireless WEP Key

1823 Views 20 Replies 4 Participants Last post by  Triple6
I changed the WEP key on my wireless router - same length, different key - and after updating all my devices, all are working fine except an old laptop that is running Windows XP. When I try to change the key on this laptop, I'm told it can't be any longer than 13 ASCII characters.

It's been so long since I set up the laptop to work with this router that I don't remember how I did it. Does anyone know how I can get it to accept the wep key for my router?

1. Why are you using WEP - as against WPA. The security of WEP Wired Equivalent Policy is far less than Wireless Protected Access and you should NOT be using WEP unless absolutely necessary - until you can update your wireless adpater
That said 128bit cannot indeed be longer than 13 ASCII characters
However it can be 26 Hexidecimal - alpha/numeric

ON WPA the limit is 63 characters
I appreciate your opinion and advice, but I have been using the WEP passkey for many years and I will not be changing. If I have to give up the old XP laptop I will, but it was working fine with the WEP protected wireless router until I changed one number in the pass key in order to prevent a particular user from using it. I know I set it up before so I know there is a way to make it work, I just can't remember. Anyone else?
As I said

it cannot on ASCII so have you tried setting it hexadecimal
OR alternatively using a less character ASCII key

I wonder if you have actually looked at the link I sent
and IMHO there is no way that you ever used WEP security with ASCII entered format key on more than 13 characters
You're using 128-bit WEP? And entering HEX digits or ASCII characters?

Thank you for your help.
Thank you for your help.
I am unsure as to what you mean
hexadecimal is alpha numeric eg 1 to 9 and a to f
ASCII includes special characters

so an ASCII key could be
*12AG£
and in hexadecimal that would be
2a31324147a3

Actually, that may be the problem. I am entering Hexadecimal, but the system is trying to read it as ASCII. I think I can enter up to 40 hexadecimal digits, but how do I tell the system it's not ASCII?

I thought it was 26 hexadecimal on 128
For 128-bit encryption - You can enter 26 hexadecimal digits (any combination of 0-9, a-f, A-F, zero key is not permitted) or 13 ASCII characters.

again - as mentioned on the link I sent.

Until you explain further relating what you are doing - to the information I have sent you I do not think I can help you further.
Perhaps my good colleague TerryNet will be able to offer different advice.

All my devices except the Windows XP work fine. However, when I try to connect the old XP laptop to the network and I am prompted for a pass key, when I enter the 26 Hexadecimal characters, the system reads them as ASCII and bombs out, telling me the key is too long. Is there a prefix to indicate Hex? Like "AC0DC6,,, or <AC0F9B...?
What wireless utility are you using? Please show a screen shot of the window where you must enter the key. Seems to me, hard to remember that far back, that sometimes it was difficult to tell whatever utility was used that you wanted to enter hex.

If you need help with a screen shot see TSG Posting a Screenshot. FWIW to take screen shots with Windows Vista or latter I prefer to use the built-in Snipping Tool.

Converting the Hex to ASCII yields weird characters: Ï k ø, etc
Since the laptop isn't on the network, it was easier to just take a

i've done that already but i'm tryimg again in case I miss typed. also rebooting this time.
Still no luck. Thanks guys, but I'm not sure the old laptop is worth all this trouble. Still, if you think of something else I'll try it.
What device is requiring you to use WEP? WPA is actually secure (with a strong passphrase) and is so much easier to use.
Indeed, as I said as well

When you say you have done that already - your screenshot shows you trying to type it in the other box that appears when you click connect
whereas my screenshot shows the window where you configure the level of security
Are you sure you have set WEP
