We have a new office, and our Draytek 2710 modem/router that worked in the old office is struggling.

It will chug along at 5 errors/min (incoming data CRC) until the shop next door arrive for the day, then it constantly comes up with 50-100 errors/sec. When they go home for the day, the errors drop way down again.

We have isolated the power, running the thing from batteries with no change.

The Telstra tech tested the lines and gave them a clean bill of health.

The neighbouring shop is retail, so have nothing fancy plugged in, and use dialup for their internet. (In fact, they seem to be having problems with their dialup since we moved here)

Any suggestions? (systematically shutting down the neighbour's equipment until the problem goes away would be a good start, but they are not fussed on that idea)
