Aironet 340 Base Station with Compaq iPAQ wireless adapter


I'm having problems connecting the new Compaq HNW-200 USB adaptor with a Cisco 340 Base Station.

That is, it works very well when I'm not using WEP, but as soon as I configure the base station to use Wep, and puts a ASCII code, they can't communicate. Another computer using a Cisco 350 PCMCIA card have no problems.

There are a few options in the Compaq utility, I can choose from "none/64 bits/128 bits" WEP keys. Does anyone have any idea what might be wrong?

Could it be that the Cisco uses the WEP like this (if key is cisco):

cisco0000000000000000000000...etc (fills out with zero's at the end of cisco) while the Compaq uses

How do I select 40/128bits WEP in the menu for the Aironet base?

Re: Aironet 340 Base Station with Compaq iPAQ wireless adapter

To check the version of WEP supported on the 340 base station, check the product name on the bottom (340 = no WEP; 341 = 40-bit; 342 = 128-bit).

If you're having problems with the way the WEP key is "filled out", the easy solution is to use a real 40-bit or 128-bit WEP key, rather than using a shorter key and hoping the software completes it correctly.

Most software (like Cisco's CEM) accepts the WEP key as a hex string (if you're using "cisco" as your WEP key, you'd have a problem), while others can accept a 40 or 128 digit binary string.

Check the documentation that came with the hardware - it should have instructions to enter the WEP key correctly.
