Thanks for the suggestion. However, when I looked at the router at the
client's home, I could verify that the ISP cable was in the correct (WAN)
port. The only cable coming from one of the LAN ports went to his PC.

Then when I disconnected it and took it home, I connected it myself and
verified the cables again.

Thanks,
