Hello guys, Thank you very much for y'all reply.
As this is my first time messing around with Router settings, I am unsure if I just missed an option.
the Lan outputs for Router #1 (in db box) dont seem to work(?) BUT it is able to give Router #2 (in living room) internet.
Currently I am able to connect to both Router #1 and Router #2 for internet wirelessly.
My connection goes as:
Optic fibre line > 1st ONT port > Internet port on Router #1 > 1st Lan port on Router #1 > Ethernet panel in DB box (to living room) > Lan port on Router #2.
----------
I can confirm that the Ethernet port for bedroom #1 on the Ethernet panel in the DB Box works. As When I connect an Ethernet cable from Router #2's lan port > Ethernet panel port for bedroom #1, my computer receives internet.
However, other Lan outputs from Router #1 does not work. I tried plugging in my laptop to Router #1's lan port and received no signal. So I guess there is something wrong with the settings or Lan ports with Router #1?
