Slightly unrelated but does the packet loss happen all the time or when close to maximum of the line.

Used to have similar problems with an ADSL line but found if I limited the line (Both up and down) I could find a magic number where the packet loss went away. (Well most of the time :))

Though it did need to be tuned for different times of they . ie high congestion times need it to be lower.

Though technically it shouldn't be your problem :(

This is normal if your router doesn’t prioritize control traffic. A rate limit allows all the ACKs to normally leave your network instead of getting queued up.

Or your router isn't responding correctly to traffic controls or the ISP isn't sending them correctly? I know with one provider I had in the deep past the allowable packet size was smaller than what most devices default to and they weren't correctly sending the maximum size their routers supported in the appropriate ICMP requests. Eventually I figured out that I could force my router to a smaller allowed packet size and that at least decreased packet loss substantially going upstream, even if whatever misconfiguration of the ISP was still confusing and eating downstream packets.

It happens nearly all the time. We use very little DSL bandwidth but are quite rural (miles from primary telephone infrastructure)

Dropped packets are often a symptom that the MTU value is set too high. That would be uncorrelated to congestion, though.
