My son has a Nintendo DS and the USB dongle to allow wifi play, but we can't get it to work.
Our set up is 2 pcs cabled to a router, router to modem. There are no problems with the network between computers or the wide wide world. The DS can link to the USB dongle, but the dongle cannot link to the internet. I found this from

Apparently, the problem is that ntl's system won't allow more than one machine per broadband cable line. With a router in place, the modem and their network only "see" one computer, but with the DS's connection-sharing setup through the USB Connector, it looks to the ntl network that more than one machine is accessing the connection and the second one is prevented from accessing.
Any bright people here know of a way round this problem?
