SoGEA/FTTC drops was created by Richard
I've a Vigor 2865 - primarily using full fibre via WAN2 ethernet, but with a SoGEA back-up on WAN1 (which was the primary connection for many years).
WAN1 has been absolutely stable for years until a few months ago.
Then I started noticing frequent (1 - 2 times per day) reconnects.
This deteriorated to becoming complete connection drops.
Going into DSL status shows it in a loop of TRAINING > FAIL > READY
Doing adsl reboot command on the console brings it back to life, as does disconnecting and reconnecting the DSL lead.
ISP has tested the line and says it's all good. I've tried a new DSL lead - no change, and had a new Master Socket installed (nothing else connected to it, and for a while I had the faceplate removed and the DSL lead straight into the "test" socket.
Firmware is 4.4.6.1_BT, DSL version 8D1B17_A/B/C HW: A
I'd be minded to believe it's a line fault - albeit the ISP says not, and not sure why an adsl reboot would resolve that?

Hi Richard,

I encountered a similar issue with my Vigor 2862 router on a SoGEA FTTC line. Like you, I found that rebooting the ADSL connection or reconnecting the DSL lead temporarily restored the connection. However, the problem persisted, even after replacing the DSL lead and installing a new master socket.

Upon further investigation, I discovered that the firmware version 4.4.6.1_BT might have compatibility issues with certain SoGEA lines. After downgrading to firmware version 4.4.5.1, the stability improved significantly, and the connection drops became less frequent.

Additionally, I adjusted the DSL settings to use 'Fast Path' instead of 'Interleaved' mode, which reduced latency and improved overall performance.

If you're still experiencing issues, you might want to consider reaching out to DrayTek support for further assistance or explore alternative firmware versions that could offer better compatibility with your line.

Let me know if you need more details or assistance with the firmware downgrade process.

Best regards

Thanks - I'll experiment with different firmware versions.
I think the start of the issues may well have been consistent with the firmware update to 4.4.6.1
