Hi


So some backstory/timeline:

We moved to Spark from Vodafone as they informed us our street would be fiber ready on the 15/10/2016 and gave us a good deal. Chorus then turned around and told Spark we cant get it so we are stuck with VDSL. Not happy but what can you do? Have been having constant VDSL disconnects ever since.

•     October 6: physically switched over to spark, on ADSL2+ using the HG659b modem.
•     October 6-17: no disconnects at all. both wifi frequencies worked great.
•     October 17: chorus tech comes and installs a master filter/configures VDSL.
•     October 17-present: constant disconnects every 5-15 minutes.
•     October 20: spark technical support says the 24 hour test logged 32 disconnects. they cant diagnose the problem other than that its not the modem and probably a line fault.

I have tried running the modem over LAN with the Wireless radio disabled with only 1 device connected. Used a Windows 7 desktop and a Windows 10 laptop. Replaced the RJ45 cable and used a new power socket. Still getting disconnects.

The error reported in the Modem Logs is WAN connection INTERNET_UMTS:IPv4 disconnected.(ERROR_NO_CARRIER). Attached is an image of the DSL information just as the line drops over a few seconds. The only variables that change during this time are the Maximum downstream rate and the Downstream noise safety coefficient.

Any ideas what the problem might be?
