first, thanks for answering in advance. 2nd, i'm completly illiterate when it comes to computers so please answer in the simplest terms possible. 3rd, i know you guys are tired of these questions, but like i said i'm completly lost and could really use some help my router (?) (box for the internet, has all the wires connects to the computer and to the wall) is a motorola surf board cable modem sb5101. ( i didnt see this one listed in the other thread). i'm getting the error message50420, LAN adaptor not properly inserted. i have a few questions. first, my router has to inputs, 1 is for a flat wire, looks like a telephone cord connection (ethernet?) the other is a USB (i thought USB looked different, but its labled USB, it loks alot like a bigger version of the connection for the sensor bar) the ether net cord goes to the computer, and normally the USB port is empty. ( like i said, this looks more like bigger size of the sensor bar plug in on the back of the wii, but its labled USB which i thought was something else, anyway, its lables USB so thats what i'm calling it) here is what i have tried i have the LAN adaptor. the issue is it needs the ethernet port to connect to the router, which is going to the computer. i unplugged it from the computer so i could use the LAN adaptor. but i get the 50402 error i have an extra cable i found that is a flat plug (not sure what to call it, but is the same connector that you would use to plug an ipod into the computer, i thought this was a USB?) its that flat plug on one end and that bigge version of the sensor bar plug on the other. so i didnt need the LAN adaptor to try this, went straight from the wii to the router, and the ethernet cord from the router to the computer is still plugged in. still the same error. does my router not have enough ethernet ports? do i need the ethernet plugged into the computer to get online with the Wii? or am i just doing something wrong you guys can hlp me with?
