How so? Guessing the MAC address of my 360? It’s just as long as the WEP password and more random, so I don’t get it. Doesnt this make the router only allow those devices to connect? so how would anotehr device connect, even if it had one of the 2 allowed MAC addresses, do routers allow 2 devices to connect w/ the same MAC?
MAC address filtering is stupid. All I have to do is sniff the packets in the air, pick out your MAC address (broadcast in the clear), and then tell the router “Hey, I’m also Spartacus!”. Ta-da, I’m in.
And routers dont mind letting 2 devices with identical mac addys on? Thats retarded. I guess I’ll change a setting when I get home. Wish my router didnt suck ,since the wifi doesnt work w/ my DS I dont use the wireless (works with my psp! how useful…), but it doesnt have an option to shut it off and use it wired only.
We’re getting a little into “oh does, the sky is falling here.”
If you’ve got some technical know-how, it can be trivial to crack WEP and sniff MAC addresses. However, if someone’s doing that to you, you’ve got larger problems because we’ve gotten away from “neighbor leeching” to “targetted attack.”
The only thing you can do is hide the SSID, do mac address filtering and use WEP. What you’re really trying to do is not make your wireless convenient.
I’m lucky, I live in a remote area and my neighbors can’t leech.
WPA-PSK is harder to break than WEP, and imposes less network overhead. Basically, unless you have at least some form of WPA on your network, it may not be wide open, but the word ‘secure’ cannot be applied to it.
If you have multiple devices and maybe a friend or family member who occasionally wants to connect, don’t bother with mac address filtering. It’s just a PITA for you and won’t stop a targeted attack. If your goal is to block the neighbors, just choose a secure password.
Also, use a good key for your WPA password, with numbers and capital and lower case letters, and maybe a symbol or two. WPA2 can be cracked with a dictionary attack, if the user has enough patience and CPU cycles.
