Hello! As you can probably see, not the biggest on networking. I have a DCP3825 Modem, I'm using it for wireless, but I'm wondering if I can use it for wired as well? It has 4 Ethernet ports, could I just use the modem itself? http://www.amazon.com/Cisco-DPC3825-Wireless-Residential-Gateway/dp/B008C4HDQA That's the Modem, I didn't exactly buy it, was installed by my ISP. Thanks in advance!
