IMO alot of those security featurs are somewhat pointless, not because they dont work or are not good ideas, some are just much more difficult to set up than just throwing on a 64 WEP. And if you have trouble in the future, (without properly understanding the technology) will probobly just lead to more hassles and headaches for you. If you really want it to be secure change your WEP key bi-weekly or monthly.
You're kidding right? I can literally crack a 64 bit WEP in as little as 30 seconds. 128 bit WEP can take a few hours or days, it require many many more IVs from captured packets. It doesn't matter how many computers are on on your network, the necessary packets that contain IVs are generated when your wireless AP transmits and receives data. Obviously the more activity on the network the faster IV's are going to be obtained, however an attacker can also inject packets into the network and generate activity if there's none currently. WEP is massively flawed and should not be used if you have WPA available, WPA is much much more secure.
Also a note about not transmitting your network's SSID: Stealthing an SSID only hides it from things like Window's 'show available wireless networks'. A stealthed SSID is easily revealed by wireless packet sniffers like Kismet. I only see 5 wireless networks while my laptop is running WindowsXP, but when I use Kismet in Linux I see 14.
Lastly, MAC filtering isn't really worth it in my opinion, and definately not viable as your sole defense. It's definately not any easier than using WEP or WPA and it's not secure at all. You have to manually enter a wireless adapter's MAC address into the router for it to be able to connect, but with the MAC address being different for every computer it takes more effort to enter them all than it would be to just connect to the network an enter the WEP key with every computer. MAC filtering is also extremely easy to bypass. Anyone packet sniffing using kismet can see the individual MAC addresses for everything on your network and all they have to do is spoof their MAC address to match one of your computers to gain access.
