Hi all, I lost the access to my modem DX5401 so I want to reset it but nothing happen using the reset key in the back. I tried to keep it 3 minutes but the modem still don't reset. Can someone please teach me the right steps to reset it?

Thanks

I think this will surely help you. Unplug the router and modem. Wait at least 30 seconds. Plug in the modem and press the power button to turn it on, if needed. Wait at least 60 seconds and then plug in the router. Press the power button to turn it on, if needed. Wait at least 2 minutes before testing or using the devices.

Router DX5401 has been bought by you or was provided by the ISP?
