Not all WEP, WPA and WPA2 work with all machines.

What we do however is update our router firmware then our machine and then test for the highest protection we can get without hammering our speed.

At home I use a combo of WEP and MAC filtering (see http://en.wikipedia.org/wiki/MAC_filtering ) Which even with the usual toys the attacker fails because even if they crack the WEP they still have to deal with the MAC address. This combo is secure enough in my view today for home use.

I agree the industry could have done better but you can get good security if you put your mind to it.
