    I currently have my router(wrt54g) setup with WEP security. I tried using WPA before, but for some reason, it noticeable dropped my signal strength. I heard that the security also slows down the overall connection speeds fro the network too. Instead of using the security settings, could I just do something with the MAC addresses and only allow certains ones to get access to the internet? Would that provide a strong enough security? Any performance problems with that?

    ps. what about WPA2?

    Without WEP encryption it will be easier for someone to see the data that is flowing across your wireless network, but as long as you have MAC address filtering on, I think you should be safe from them actually using your network (unless they guess your MAC address and spoof it...not sure how easy that would be to do). I personally think WEP is strong enough for most home networks, especially if you change the key every so often (depending on how much data flows over the wireless network). I generally use WEP (128-bit) + MAC address filtering. The performance loss isn't really noticeable to me, though I haven't run benchmarks to test it. If I was going to do gaming or something, I'd want to be wired anyway.

    using certain tools that are availble free off the internet. someone can see your mac addresses very easily as they are sent in the clear. if you are concerned about people jumping on your wireless, don't rely on just mac address filtering.

    go with what gotamd said. Do the wep + mac
