I have a notebook computer that stopped connecting to my wireless network. When I try to go into the wireless network properties and enter the WEP key, it will not let me enter the entire 128-bit key. I haven't changed anything on the main router (D-Link) in quite some time. The laptop uses a LAN-Express router. The wireless network properties box doesn't give me any way to specify the key length. It only has a checkbox for Data encryption (WEP enabled) and Network Authentification (Shared mode). It then has the box for entering the key and the confirmed key. The box will only allow me to enter 23 characters. I don't remember this being an issue before, but it has been so long since I set up this computer, I really don't remember. Any ideas?

With 128 bit encription you to insert only 13 ASCII characters. ith 64 bit you need 5 characters.

That is incorrect.

A 128-bit WEP key is almost always entered by users as a string of 26 Hexadecimal (Hex) characters (0-9 and A-F).

As for a solution to your problem, the box might only show 23 characters, but they may be scrolling over as you enter more. Of course, this is impossible to notice, since all of the characters are either shown as dots or asterisks as you enter them. Just try entering the whole key without worrying about the size of the box, and see if it works.

ASCII and hexadecimal are not the same. You can enter either 5 ASCII or 10 HEX charachter for 64 bit and 13 ASCII or 26 HEX for 128 bit.

I never said they were the same, I just said that 26 hex characters are almost always used, and I'm willing to bet that it is what the OP uses.
