FTTP: can I instal a switch between ONT & router(s)?

Go to solution

Hi,

we're having fibre installed to our house. We have a a couple of outbuildings that I'd like to extend the fibre to I want to know if I can install a switch between the ONT (which by my understanding is the fibre modem) and the router in each building. I could theoretically use the BT smart hub but then it's not in the best position in the house for wifi.

So ideally

ONT > gigabit switch

gigabit switch port 1 > (via Cat 6 cable)  > smarthub located centrally in the house

gigabit switch port 2> (via Cat 6 cable)  > a.n. other router in outbuilding 1

gigabit switch port 3 > (via Cat 6 cable)  >  a.n. other router in outbuilding 2

I have spare ducting that I can pull the cat6 cable through from the switch to each outbuilding.

Many thanks for any thoughts / advice.

David

Welcome to this user forum.

No, you can only have one router connected to the ONT.

You can however extend the Ethernet output from the home hub, to a switch, and connect a wireless access point on the end of each of the cables. That would work fine.

The TP Link WA801ND access point would be suitable.

Thanks for the very swift and clear response Keith.

 

Does it matter where in the system the router is?

Ie. could I have the switch between the ONT and the router and keep my proposed layout as long as I had wireless access points (instead of routers) in the outbuildings?

Yes, the switch must be in your LAN not WAN. The ONT must connect directly to the WAN port of the hub and nothing else.

Ok - thanks for confirming.

So 

ONT > WAN port of a hub / router

Then out from the LAN ports of that hub / router to wireless access points / switches as needed at the various locations including the house to get over the location of the ONT and the hub / router.

Many thanks

That is correct.

I know this is an old thread, but you actually can put a switch/hub between the ONT and the router's WAN port.

This is exactly what I do, running a VM as my router rather than the SmartHub.

You should put the link from the ONT and the link to the router in a separate VLAN from everything else.
