Hey I got a new router and so far it seems to work for my ds but when my sister was using her laptop i didn't allow her to go to the internet but it usually does could this be because I changed the setting from the origanol?
Possibly, but I don't know what you could possibly have changed, I've been on the internet on my desktop and laptop and get a connection for my DS at the same time. I would suggest reverting back to the default or older settings.
