1. I don't think you're reading the model number. I think 12vdc is the power supply (12 volt DC)

. Check the tag for the model number. You should be able to google the model number to prove its valid. Then post the model number
2. Odd in that (based on the IP address shown in your ipconfig) your wireless device connects directly to your ISP. So i don't know if you really have a router??? (As i would think your PS3 connects to it?) And if you do, maybe your wireless card doesn't use it but connects directly to ISP? So i'd like to find out what your modem/router equipment actually is /* edit */ to first understand how your wired and wireless network ports and your PS3 network and connect to the internet (and each other)
So would like the model numbers.. and does your moto modem connect to an incoming ISP cable?>
