Deco router will not connect to the Wi-fi
Deco router will not connect to the Wi-fi
I have no issue connecting my devices to the Deco router, but the router will not connect to the internet. I have an Arris modem from RCN. I called RCN and they can see it's not connecting but they said they did everything they could on their end. Please help. I'm at my wits end with this.
