My Mdoem's ethernet and usb lights are off

The PC link light is your indicator if there is a device connected to the modem through the ethernet port. If its off, then you may need to check the connection once again whether it be a PC connected hardwired to the modem or a router. Replacing the ethernet cable can also help because it might also be a defective ethernet cable. As long as the internet and cable activity lights are both solid, its ok because that means your modem is receiving the signal from your provider.

remove all the cable conencted to your D-link except for the power cable of course ^_^ if the lights stops from blinking then possbile one or more of the ethernet ports on your router is malfunctioning try connecting the modem to your router by trying all the ethernet ports on the router until you see the lights stop from blinking if the lights stop blinking then that port is still usable on the router but in any case it also may be the routers settings you might need to set your router to the modems settings depending on your internet if it is DSL and you are using PPPOE there must be a user name and password that you need to input in the router for a calbe modem no need but since your situation is as we speak I do not think you have a cable modem for your internet, you might need to call your Internet service provider as well for further info for the user name and password the mdoem has unless you know how to get the user name and password from the modem ^_^ as far as I can go that's all

unplug modem for 30 seconds and re-plug if that fails do a hard reset ( button).

power down cable modem, router, and computer. Connect ethernet cable from modem to router/ and connect ethernet cable from router to PC. Power up cable modem first, after modem shows connectivity, plug in router. After router shows internet connectivity, start computer. Be sure that you LAN card operable

if you dont have a router, you can either have the xbox or the pc conneted to the internet, not both. you have to have an eithernet cord or a usb 2.0 high speed usb chord that goes directly from the xbox to the modem. you cannot go from the modem to the computer then to the xbox.

1. USB modem is connecting a PC USB port with a DSL phone line: CANNOT be connected to a ROUTER LAN (ethernet NOT USB port).
2. Wireless ROUTER is NOT a modem and it CANNOT connect the Internet (or WAN) LAN port to any "phone line"
3. Connect the Router Internet (WAN) port to Modem (you need a LAN MODEM = a modem with a LAN/ETHERNET port)
4. Be sure your internet is running before strting ROUTER configuration with Router Company CD
   

Have you installed DSL filters on all your phones and make sure you don't have on on the line for your modem?

have you tried connecting it directly to the router/modem that you have?
