Okay, I had the same problem (yay for you =), and yes, it is really really annoying. There are a few things you can do to fix it.
1. When connecting, stand directly in front of your router, hold the ds as still as you can, or try different places in your house for a "hotspot" where you can get good connection.
2. Register your computers DNS, helps improve chances of getting online
3. If all dont work, try a different router, ds, or go to McDonalds, they have perfect wifi there =)
BEST OF LUCK!!
