We have an identical issue as this post 2 years ago, "Problem - Zyxel USG-100 PLUS - FTTH Fiber Limit to 100 mbit/s": //community.zyxel.com/en/discussion/3434/problem-zyxel-usg-100-plus-ftth-fiber-limit-to-100-mbit-s/p1
Just had a customer upgrade to a Fibre to the Premises (FttP) connection - 250Mbps download/25Mbps upload plan using PPPoE connection. If we connect the ethernet port notebook directly to the FttP, then we get full upload and download speeds.
However if we connect the Zyxel ZyWall USG100 Plus (latest firmware), we obtain full upload speeds but only 80Mbps on download. We have BWM, ADP, Content Filter, etc all currently disabled. WAN1 shows 1000M/Full connection as does LAN1 so can rule out auto-negotiating at 100 or lower - see screenshots below.
With this particular Zyxel model should we be able to reach closer to 250Mbps. And if so how do we troubleshoot? Older post quoted doesn't appear to have an definitive answer - although last post suggested only 30Mb/s throughput.
