Same IP address range dished out from the modem that your Trendnet is using for its own LAN IPs? If so, it will get confused and not work.
Did you also verify that they are plugged them modem into the WAN port on the Trendnet and not one of the switch ports?
I sorted it out. Client had not gone into the trend net router and put in the new password and username from Primus. Still had the Bell password and username. All is well.
Thanks everyone.
Oh and good call about a static IP and the DMZ. I like that idea. For systems like Bell Fibe where I can’t bridge the router.
