Yes it is a DrayTek Vigor 130. It just works. No evidence of anything wrong with it.
That might be partly related to the limitations in what data it provides you.
This thread started out with:
What is the best way to health check your broadband line?
What tools can you use?
How can you tell a fault from a non-fault?
Can Broadband Boost or SFI2 improve things even if there is no clear fault?
The answers to the first three, without specialist test hardware, are generally:
- Use a modem that will give you complete statistical and synchronisation information, which describes the line state, and watch it for changes.
- Use a PC or Linux-based tool that interrogates the modem for that status data, and presents it in graphical form over a long, long period. Starting, preferably, when the line is healthy.
- By analysing the graphs of long-term behaviour, mixed with some skill from previous analysis ... distinct "on the job training" here. Key, though, is watching for changes over time.
When faced with a Draytek modem, I am reminded of the punchline to the old Irish joke: 'Well sir, if I were you, I wouldn't start from here'.
I assume that, when you presented the set of detailed stats earlier, you replaced the Vigor with something useful? They look more Broadcom-oriented.
