whats a "needs of a USB stick"?It depends off course, the store and the needs of your USB stick. Here it is around €50 for a nintendo WiFi-USB, which probably is enough for a little router. So I should go for the router.
Side note: don't your neighbours have a router? Most ones aren't secured...
and no, our neighbors dont have WiFi either, The NEAREST hotspot here is about 2 and 1/2 kilometers, an Internet cafe, and the owner is GREEDY about their WiFi, even though no one is using it. I brought my DS once out there when I first searched for access points, they didnt knew it at first, the next time I went there to trade, and when they saw me, they shut off their routers and I lost WiFi(they must have shut it off because I cant connect anymore), so, I nowhide when using their WiFI, I cant get inside the cafe anymore because they might shut off their routers again.. so I now just squat-hide at the side of the cafe so that they will not notice me, rather than going inside and realising that WIFi is gone.
they suck. and the next Hotspot is about 500 meters from that cafe, so its really tiring when I ask for trades, but if the pokes are good, Ill dont mind the running of about 2 1/2 Km in 5 minutes.. :D
