Topic: Using your 3DS to play DS games online

Not sue how many of you know this but I thought it would be good to talk about so you know. Regular Nintendo DS games support on WEP security. The encryption is old and easily hacked. Most new home networks are set to WPA. what this means is that if you have a modern encryption on your home network you cannot play DS games online. How does this tie into the 3DS you might ask? Well the 3DS does support WPA encryption and as such you could going to the eshop, surfing, etc without a hitch and then suddenly decide you want to play Mario Kart DS online on your 3DS and find you can't access the network. This happened to me with the DQVC in Dragon Quest 9. I was thinking my 3DS was preventing me from accessing online content when it was in fact the DS cart's incompatibility with WPA.

I have my belkin router bridged to my BT homehub so I have 2 signals, both of them being hidden.
I advise doing this to anyone who is able to, if not buy a wifi adapter to downgrade your wireless security which I do NOT recommend.

It is definitely an inconvenience =/ At least your 3DS runs original DS games lol mine run sooo slowly and they freeze when I try and play local or online multiplayer. Nintendo's customer service has yet to reply to my email .

Is it easy to change your router's security? You could just change it to WEP whenever you wanna play online, then change it back after. Not the most seamless solution, but apart from leaving it on WEP, it seems to be the only fix.

Well, I found that the only DS game I can play online is Pokemon Black and White. I've had a similar problem to yours playing Warioware DIY online with the 3DS.

Pokemon Black and White support WPA on DSi, too. It must be the "DSi enhanced" mode or whatever.

Everything works fine for me.

Its not hard but then ever pc in the house needs a setting update if you don't put it all back just so after....

Is it WPA or WEP though? Using a packet sniffer I could have your WEP ID and password in a matter of minutes even though it's hidden to those who don't know much... You need to worry about the savvy people, not those who are going to give up at the very first barrier. WEP is a security liability. I will make the switch, download the the DQVC DLC for DQ9 and them move back to WPA immediately and be done with it. No Mario Kart DS online via... Good thing there is a 3D option on the horizon!

My Belkin is WEP and it MAC Address filtered so
My bt homehub is WPA2, not stating how long the key is as it's a breach of security but I know it all off by heart
edit: also my wireless light lights up when there is a connection and I always investigate it, if its not me or anyone in the house... both routers go off and out comes the camera for people or parked cars outside the house

MAC filtering won't save you either with WEP. A packet sniffer and a cloned MAC address an hour later and suddenly some d bag is essentially booting you off your own network...

Yeah but you need specific hardware for that, unfortunately I don't have the hardware... and I hate my neighbors... enough said

Yeah you need a Wifi card, which comes stock in virtually on all new PC's. Then you need a packet sniffing program. If you know about packet sniffing then finding an app to do it should be a non-issue.

It's worth noting that all DSiWare with online multiplayer support WPA, so you can play those online with the 3DS

I'm not sure how you're set up but if PCs in your house can/do connect via WEP then it can easily be broken into. All someone needs to do is us a packet sniffer to get your password and PC MAC ID. Then all they need to do is clone that MAC ID and they have free reign to watch paint drying videos on YouTube or what ever else they can think of.... Oh and then theres the minor detail of them knock both you and them offline when both of you try to surf at once because routers/gateways don't allow for two devices with identical MACs.

There's actually an easy fix I figured out. Go to your 3DS' System Settings, click Internet Settings, then Nintendo DS Connections. Start a new connection (for some reason, the same connection that crossed over from my DSi didn't work, even though all the settings were identical) and connect as normal. DS games should work now. WarioWare DIY didn't worked before I did this, now it works fine.

point, but lets face it... most people don't know how or can be bothered.
lucky for us hey.

Most people aren't going to crash on the highway but you won't catch me not wearing a belt because of it.

Have I offended you? if so sorry :/
Let's get back on topic, wifi usb adapter works well.

I'm not sure what I said that would make you think I'm offended but reasoning into why WEP sucks fits in with the topic. I'm trying to offer helpful information.

Anyway a USB wifi cable is something I didn't know existed. Interesting. You just plug it into you router and youre on with you DS or 3DS?

for ds games, i need to remove every protection i have on my router. this way i can play every ds games that could use wifi connection.
of course, i do it temporarly, like checking dragonquest 9 VC shop, or downloading new puzzles for picross DS.
any hotspot location are not working, i tried.
i wont lsit them all, but GTA chinatown, the world ends with you, dragonquest 9, picross DS, picross 3d all worked top notch.

***edit***
my router is a cheap microsoft router, dating from years and years ago. maybe finding an old router could help doing ds wifi gaming.
