Forgive me if this seems dim but pondering wireless security isn't the key thing to enable MAC filtering and to hide the SSID, particularly as WEP seems laughably easy to crack and WPA isn't widely enough supported?
I would have thought that if you restrict the machines able to connect to the network and hide it then the more fiddly stuff is redundant ...
No security measure is perfect. None of them will stop a determined hacker from entering your system. None of them will stop a detrmined hacker sniffing your packets and getting your details.
All these processes make it harder for an amateur, so hopefully the hacker will move on and try his luck elsewhere. In this respect, locks on doors and windows deter burglars, they don't totally prevent burglary.
WEP adds to the protection of the network for a small drop in performance. It doesn't affect the speed of web browsing or email and the effect on download speed is probably not measurable. It would only have a measurable effect on file transer speed.
Only you can judge whether the reduction in speed outweighs the increase in security.
Whilst WEP s crackable, it is beyond most amateur hackers.
