I currently have my modem connected to my PC with a USB cable, but having evaluated my connection I've decided to change and use the ethernet port on my modem to connect to my PC. I've tried simply switching to the ethernet cable from the USB cable, but my computer won't connect to the internet. What configurations do I have to change for my modem and PC to connect using ethernet as opposed to the current USB?

Check to be sure your ethernet is not disabled shut down the computer and unplug the power supply from the modem. Power up the modem first then turn on your computer.

I suggest calling your ISP to tell them you're making the change. They may need to change something on the modem.

make sure you leave the modem off for at least 10 minutes. Same goes with a router if you have one.

The ISP doesn't have to change anything to change interfaces. The advice to power down the modem is the correct way to fix this.

I thought the two interfaces had separate MAC addresses that might need to be registered. But JohnWill has more experience with this than I. If he says no changes need to be made, he's likely right.

I've seen this several times on both cable and DSL. Since there is only one IP address available for most home accounts, the interface that is "initialized" and connected is the only one that works. When you power cycle, the modem configures the interface that is currently connected, hopefully the Ethernet in this case.

interesting.... I thought it's only one, even though there is two...

research time!

The ISP only see a single MAC address from a USB/Ethernet modem, however the customer side does present two MAC addresses.
