To determine if the issue lies with your modem or router, first, check if you have internet access directly from the modem by connecting a device directly to it via an Ethernet cable. If the internet works, the router may be the problem. If not, the modem might be at fault. Additionally, observe the indicator lights on both devices; if the modem’s lights suggest no connection to the internet, start with modem troubleshooting. Conversely, if the router’s lights indicate no local network connectivity, focus on the router.
FAQs & Answers
- How can I test if my modem is working properly? Connect a device directly to your modem using an Ethernet cable and check if you have internet access. If there's no connection, the modem may be faulty.
- What do the indicator lights on my router and modem mean? Modem lights indicate internet connectivity status, while router lights show local network status. No internet light on the modem suggests a connection issue, and no local network lights on the router hint at router problems.
- Why is my internet working via modem but not through the router? If internet works when directly connected to the modem but not through the router, the router is likely causing the connectivity issue and may need troubleshooting or replacement.
