I have my wireless router set up on WPA as it's the most secure, my ds won't wi-fi connect to it. Is there some kind of firmware update around or am I going to have to downgrade my router security?
unfortunately you will have to downgrade. This was an incredibly stupid decision on the part of Nintendo.
the usb adaptor would also use WEP, and it would in effect be peer-to-peer wifi, which is extremely unreliable.
you should set up your router with a wireless access list which has all of the connected devices' MAC addresses. it is better than WPA and WEP key encryption because it only allows specific devices to be connected to your network.
ok thanks guys, will maybe get a seperate router just for consoles, I've got a spare sitting round somewhere, Nintendo should be shot.
i have WPA2 but again with nintendo, i can't use it. the wireless access list is the only option i really have other than a free connection where anyone can connect. nintendo really got cheap on their internet capabilities. im in a spot in my room where i can get my ps3 and psp to connect to the internet, but my DS won't.
But wouldn't that defeat the purpose of using WPA for more security? At that point you might as well just switch the current router to WEP and save the money.
The idea is that you have a router just for the DS running WEP which is then MAC locked to the DS MAC-address only, that way hackers would have to spoof the MAC-address to gain access. You can then further lock down the router by only allowing data on a certain port through (whichever the DS use). That way it's limited how much a hacker can do.
demiltarized zone. Basically its a port on your router that is outside the firewall. Usually used for servers etc that need to be accessible from the net, it is useful for wireless because in the event of the wireless getting hijacked, the firewall is still between the hijackers and your computers.
