Check DSL Status over Ethernet with Vigor 130 Modem
VII. Router Diagnostics
DrayTek Vigor routers when used in conjunction with a Vigor 130 (VDSL2), Vigor 166 (G.fast) or Vigor 120v2 (ADSL2+) modem, can display DSL line information over an Ethernet WAN port, with no setup required.
This allows you to view the modem's DSL line speed, SNR (Signal to Noise Ratio) and line status from the router's web interface without needing to change cabling or configuration. This information can then be used to determine actual line speeds or for remote diagnostics.
When connecting a DSL modem to a router's Ethernet WAN port, it would typically not be possible to access the modem's web interface. This is because the router's WAN connection is with the ISP, not the modem. The modem is simply a transparent link for the router to access the ISP - a DSL to Ethernet bridge.
With PPPoE connections, this is because the WAN interface on the router would only be passing PPP packets through the interface, instead of IP packets, which would typically make it impossible to access the modem's web interface to view DSL Status information.
With Static or Dynamic IP based connections, packets route directly to the Internet gateway of the WAN interface and cannot access the modem without losing access to the Internet through that connection.
When a DrayTek Vigor modem is connected to the Ethernet WAN port of a DrayTek Vigor router and the router's firmware supports the facility, the DSL information will be shown on the [Online Status] > [Physical Connection] page.
This information is sent by the modem periodically so there may be a slight delay in reporting:
The state of "TRAINING" indicates that it is searching for a VDSL signal to sync with.
When the line is connected, it will display "SHOWTIME".
When the line State is "FULL INITIAL", that indicates that the connection is currently syncing with the ISP.
The DrayTek Vigor 130 and Vigor 120v2 modems send DSL Information to the router by default.
The DSL information is sent as a UDP broadcast packet on port 4944. If this isn't required, it can be disabled from the [System Maintenance] > [Management] page of the modem's web interrface, by disabling the Broadcast DSL status to router option:
The DrayTek Vigor 3900 and Vigor 2960 routers with firmware version 1.2.1 and later support displaying remote DSL information for each DrayTek Vigor modem that is connected to the router's WAN ports.
This information is displayed from the [Online Status] page of the router's web interface. This can be accessed from the Operation column for the WAN interface with the modem connected by clicking the list icon highlighted in the image below.
This option can take a couple of minutes to display upon initial connection:
That will pop up the Remote DSL Detail window to display ADSL and VDSL information for the line connected to the port:
It can also display the Line State when the ADSL or VDSL connection is down, such as this example, where the PPPoE connection of WAN1 is down because the VDSL2 line has been disconnected:
The state of "TRAINING" indicates that it is searching for a VDSL signal to sync with.
When the line is connected, it will display "SHOWTIME".
When the line State is "FULL INITIAL", that indicates that the connection is currently syncing with the ISP.
