Slow LAN speeds on VMG8825-T50 with 1000Mbps plan



I am hoping to get some help with an issue I am seeing with slow LAN speeds on my Zyxel VMG8825-T50 router.

My internet plan is for 1000Mbps (1Gbps) and my WAN connection shows full speeds. However, my wired and wireless devices on the LAN are only getting around 94Mbps speeds.

From my research, it seems the VMG8825-T50 supports gigabit LAN ports. However in the router admin interface, I cannot find any settings to change the LAN port speed to 1000Mbps.

Things I have tried:

  • Factory resetting the router
  • Checking all related settings like QoS, NAT, WiFi channels etc.

My questions:

  1. How can I enable gigabit (1000Mbps) speeds on the LAN ports? Is there a setting I am missing?
  2. Would a different Zyxel router model allow this configuration if the speed cannot be changed?
  3. What other suggestions do you have to get my LAN devices to connect at speeds closer to my 1000Mbps internet plan?

Btw. I'm using a CAT 8 cable. So should be fine.

Thank you!
