We are running an NT4 network in one building with about 50 users.
I have recently installed a LinkSys WAP with a 32-bit WEP encryption key, so when our sales guys come in with their Thinkpads, they don't have to fight for network points. I have programmed the encryption key into their laptops, so they join the network as soon as they log in with their Windows Network id and password.
Now our parent company is saying that our WAP isn't secure and can be hacked quite easily from outside in the car park, even though I have installed the WEP encryption.
Running Network Stumbler on a laptop, it's possible to identify the SSID, but this shows as secure, so unless you know the encryption key, you can't get on to the network - or can you? Can you please tell me if it's hackable, and if so, what can be done to secure it, so I don't have to take the backward step of removing wireless access.
Any informed comments would be much appreciated.
