Packet trace must be an option on your device, if not then its not possible since you got a DSL device from the look of it
I am not familiar with your device, but from the stats you have posted it seems your link is a either long or noisy.
There are a bunch of CRC errors, and your link has been retrained 11 times during the last 13 hours. Which can indicate that its noisy, or its just impuls noise.
Cant help you much more, since I am not familiar with the product nor the ISP.--
