my wireless router is set up for 26 digit WEP security.
My 770 only allows me to enter 13 digits. is there another way to do this or do i need to change my router setup to 13?

770 doesn't support 256 bits WEP key, so you'll have to use a 13 ASCII long key, if you want to use 128 bits WEP.

This is incorrect. The unit has the same problem with 64bit WEP keys for some reason. Even though Windows takes 10 ASCII characters for a 64 bit WEP key, the 770 wants 5, and with a 128bit WEP key, which is 26 ASCII characters, the 770 wants 13?

It was reported in another thread that you must use HEX values in order to input the thread correctly. I have not had a chance to try this as I ended up setting up another router without WEP security (which is a Joke anyway).

eh? 64bit on MacOS and Windows is 5 ascii letters, and 128bit is 13...

i know this from setting up 23 netgear routers and infinite amount of airport expresses while working for Apple

An ASCII character is encoded on 8 bits. A WEP key is the concatenation of a shared secret key and a 24 bits randomly generated initialisation vector (IV).
The so called shared secret key is the key shared by all the users of the network, i.e. the one you type in the 770 UI.

So, if you take a 128 bits WEP key, it is then composed of a 104 bits shared secret key + 24 bits IV. Thus the shared key is 104/8 = 13 ASCII characters long. Apply the same logic to a 64 WEP key, and the shared key is 40/8 = 5 ASCII characters long.

Then, an hexadecimal digit is encoded on 4 bits. As a consequence, a 128 bits WEP key hexadecimaly encoded is using a 104/4 = 26 hexadecimal digits long shared key.
10 HEX digits for a 64 bits WEP key.

Again, the shared key is the key that the users are supposed to share and this is the key that you entre in give to both your AP and your 770 as an input. And to summarize it all, they should be that long:
  • ASCII input
    • WEP 64: 5 digits
    • WEP 128: 13 digits
  • HEX input
    • WEP 64: 10 digits
    • WEP 128: 26 digits


If your AP allows you to enter ASCII encoded WEP keys (try using letters. higher than F), then enter they same key in ASCII in your 770. Same thing for HEX encoding.

Wrong. From the 770 UI you can select either ASCII or HEX input.

I run my wireless computers on a WEP 128 bits HEX, and the 770 is one of them.
No problem.

Sorry, what was it you know?

People here would like answers rather than where you worked.

It sounds like you could be of help, but there is no need to start with binary.. very few people here understand ascii.

I don't mean to offend.

There is a limit to the keys used by this device. If you want to fasten your suspenders to your pants, tuck-in your shirt, and pin your shirt to your underdrawers, you may be a little too careful.

We just want to connect.
