I've been looking round and can't seem to find anything that would work. I think it would be a very useful application - imagine if you and a friend are sitting around with your laptops and decide you want to play some networked games together, but didn't bring a cable? You could just power up the DS and make an instant LAN!
Please, if this already exists, point me in the right direction! If not, I have very little programming knowledge, so I regret to say that I would be no help in creating one, but I would certainly support anyone who wanted to in any way I could!
Thanks for your help.

I don't think you thought your cunning plan all the way through...

How so?
#165294 - josath - Tue Dec 16, 2008 8:48 am
If the two laptops had wireless...why not make them connect directly to each other, instead of going through the DS's very slow wireless?
#165295 - b3wbs - Tue Dec 16, 2008 9:36 am
Because Computer-computer [ad hoc] wireless networks are hard to set up and unreliable, and i just thought it could be a quick [obviously not in speed], simple solution.
How slow is the DS WiFi anyway?

In theory it's a 2mbit connection, but the highest actual data throughput I've heard is 1mbit (approx 128kByte/sec).
#165298 - b3wbs - Tue Dec 16, 2008 9:46 am
Surely that would be fast enough to have 1 - 1 connection to do some file transferring/simple LAN games?
#165302 - bean_xp - Tue Dec 16, 2008 12:30 pm
Possibly, but you'll be able to setup a much more reliable connection between the two laptops. Also you'd probably need to have your DS charger with you, which would defeat the object of not having a cable.
Can't you just put an ethernet cable in your laptop bag? It would probably take a lot of work to get a good connection passing through DS homebrew, and as it's largely pointless when you can use ad-hoc I don't think you'll get anybody working on it.
#165303 - b3wbs - Tue Dec 16, 2008 12:59 pm
hmm fair enough. I just thought it might be a cool thing to have.
#165304 - Maxxie - Tue Dec 16, 2008 1:11 pm
I'd still advise ad hoc. It is _not_ less reliable then infrastructure wlan.
And it is not very difficult to set up. Assign an ssid and wpa-key. Set up ip address and let the other one connect to that ssid. Done.

In theory, yeah sure, but it never really works that way does it :P
Ah well I suppose I'll have to live with that.

Oh it does. Use it on a regular base at uni, enjoying breaks with a lil gaming session. Works like a charm.
If you got problems setting it up, just ask.

I can confirm what Maxxie wrote. I used it a lot. It's also rather simple under WinXP.

Don't forget the DS would need to act as a DHCP server if it's going to be "easy".

Porting a DHCP server would be relatively easy, the problem would be to have full access to the wifi hardware to allow something like HostAP.
It still would be pointless (and racist ;-) )

Any reason that one couldn't port the tools on linux for breaking wep keys? I don't know anything abou tthe wifi specs...

I think this has been discussed before, basically the DS would be very slow at finding the key, and the DS wifi hardware is probably too slow (2Mbit) for most wireless networks to reliably capture the data. Although a tool to obtain the keys from captures exists for the DS, it is thought obtaining the captures isn't possible for most networks.

there is a tool floating around on the internet wich is build for the nds wich can capture packets and also can get the webkey.

No there isn't.

I'm highly dubious about running that application.

same here. it does look like a slightly modified version of sgstairs wifi_lib_test. I would be really surprised if it was able to do the things it claims...(the wep cracking bit - not the parts that I know work in sgstairs app) not going to try it myself though.
#166304 - Lynx - Wed Feb 04, 2009 3:45 pm
I played with it. Nothing really worked.. Could be that I just don't know what I'm doing, but I was unable to capture any packets aside from broadcasts. Maybe if I get some time later, I'll capture some packets using Wireshark and put them on the DS just to see if it had valid data what the outcome would be..

wifi_lib_test can only capture management packets so this is not surprising.
#166358 - sonny_jim - Thu Feb 05, 2009 9:08 pm
Also the 'Speedtouch hack' is just a keygen based on the digits in the ESSID, so it's not really a 'cracker'.

I believe 2mbit WiFi is 1mbit in each direction.
#166666 - Maxxie - Fri Feb 13, 2009 3:36 pm
There are no seperate physical directions in wifi. The one occupying the frequency gets it all.

Although, it would be true if you are using maximum capacity both upstream and downstream at the same time. Correct me if this is a wrong understanding:
Inbound Only = 2Mbit
Outbound Only = 2Mbit
Inbound/Outbound = Shared 2Mbit (theory 1Mb each way)

Actually much less then 1mbit in this case.
At any time only one successfull send can occure within visibility.
Within this send it's using the full 2mbit (and this is where the hardware limit is)
On top of that several software/protocol restrictions will reduce it:
Preamble: While helpfull in snchronizing and collision detection, this is no payload and reduce the netto bandwidth
Collision Detection if two stations send at the same time and see each other sending. Both will abort and leave the channel free for some small amount of time before they retry
Collision Detection if two stations do not see each other but the recipent does. It can advise all but one station to be silent for some time so that he can listen to one alone.
Acknowledgement, other management and control frames. There is no netto data in them that contributes to the effective bandwidth, but occupies some time.
The more sending stations the more "timeslots" will be thrown away, but each timeslot will still be able to be 2 mbit.
