Hi, I am quite new to this forum and still learning the basics of networking.

I have reasonably new house which has a "network box" in the garage and my entire house is wired with LAN cables to a "CAT port" to a wall.

We are using SPARK as our ISP. 

Our current set up is that we have the fibre network to the ONT (huawei unit) that attaches to one of the LAN cable which is connected to CAT port in one of our room, which has a wireless router attached. 

Due to number of growing network devices that is clogging up the WIFI, we were hoping to have wired internet available to all of our "CAT port", so that we can have wired network to some of our big devices (TVs, 2 computers) 

I have tried attaching the LAN directly to the ONT and it didn't work.

Dear experts what do I need to do to achieve this.

Regards

John
