When to Call a Professional
Contact your ISP if the error persists after trying all troubleshooting steps, as the issue may require account provisioning or service line repairs that only they can perform.Frequently Asked Questions
What does DHCP failed mean on my ARRIS router?
DHCP failed means your router cannot automatically obtain an IP address from your internet service provider. Without an IP address, your router cannot connect to the internet or provide network access to your devices.
Why does my ARRIS router keep losing its IP address?
Common causes include loose cable connections, ISP service issues, outdated router firmware, or your ISP changing DHCP lease settings. Power cycling equipment often resolves temporary connection issues.
How do I force my ARRIS router to get a new IP address?
Access your router admin panel, go to Status > Connection, and click 'Release' then 'Renew' to force a new DHCP request. You can also power cycle the router and modem to trigger a fresh IP assignment.
Should I call my ISP if my router can't get an IP address?
Yes, if troubleshooting steps don't work, contact your ISP. They may need to refresh your account, check for service outages in your area, or re-provision your modem on their network system.
Will factory resetting my ARRIS router fix DHCP issues?
Factory reset can resolve DHCP issues caused by corrupted settings, but it will erase all your custom configurations. Try other troubleshooting steps first, and use factory reset as a last resort.
