"Either which way, if access requires a WEP, hopefully only
those with the key can gain access."

Although one hopes that it is unlikely in most given situations, WEP
Wired Equivalent Privacy can be broken in well under two minutes by a
determined hacker with the right tools and knowledge at their disposal,
there are even kits available in the Internet underworld for doing this.
WEP does not use a truly random number generator to drive the encryption
algorithm, and it is therefore possible if someone was to sniff the
traffic to eventually get enough traffic in order to break the cipher.  

WPA is much stronger and although it may not remain uncrckable forever
it is by factors so much harder because of the random number generator
that drives the algorithm to all intents and purposes uncrackable at
full strengh.  Even at 24 characters there should be enough strengh to
make it pretty inpractical for anyone to try cracking it.

If you really want to make life difficult for anyone attempting to
access your wireless system I would suggest going here and getting
yourself a completely randomised key that you can use to sucure your
network.  It may seem over the top but it is here if you want:

The eagle eyed among you may realise these are brought to you by the
same chap who did the shields up thing five or so years ago, it is still
useful today to test your router security.

Hi Andy,

When you have wireless, the SSID can as you have found out,
be either shown or hidden.  There's nothing sinister in it,
just that for example, a hotel might have wireless access
for its guests, and one for it's own use.  Therefore they
don't want to publicise their private one.

Either which way, if access requires a WEP, hopefully only
those with the key can gain access.

George.

    Just trying to understand why hiding SSID on a wireless
network is so 
important when a wep pass key has been created? -
