NB604 Netcomm modem is constantly dropping out internet

Level 2

The internet from the NB604 modem keeps dropping in and out constantly.


The connection is a wired PC.


I have updated the firmware to the E5.CZ56T-B-NC from the support website.


Using diagnostics on the gateway it says xDSL sync FAIL and the tests to ISP are disabled or FAIL.


The WLAN light has also stopped flashing after I restarted the modem.


I have reset PC, power cycled the modem and reset the modem using a pin.
