I recently had my modem installed and we have a static IP on it. If I plug a laptop directly into the modem, everything works fine. When I plug the modem into my switch (accessing VLAN ID 3) and connect my computer to a different switch (also on VLAN ID 3) I get an IP address on my laptop, and I can access the modem, but the modem does not route any traffic through to the internet. Is this a configuration issue on my modem? Please advise.
