2nd and 3rd downstream routers cause SLOW up/down speeds

If I connect directly to the lan port on the fios router I get good up/down speeds. 35M/25M for example ...even 102M/25M at one time.

However, if I connect a 2nd router to the fios router (via one of the 4 ports) which defaults to assigning a dhcp address to an attached device the 2nd router is assigned its WAN address (ie. 192.168.1.3) via the fios router.  Then I set up the 2nd router to either hand out IP to the LAN (via DHCP - ie 192.168.20.x) or set a range (ie 192.168.20.1 to 192.168.20.25).  All works and I'm able to connect to the internet just fine and with a 3rd router can split my LAN in two. (3rd router has WAN of 192.168.1.4 and LAN IPs of 192.168.30.x) and that works fine too..... 

HOWEVER, my up/down speed drops on the LAN for the 2nd or 3rd router.  5M/4M for example.

If you haven't figured it out, I'm trying to setup two sub-nets so one can not see the other's attached devices.  This was the best way I could think of making that happen. 

Does anyone know why my up/down speeds may be slow on the downstream router??

Does anyone have any other suggestions for creating two subnets (basically split my LAN)??

Thanks in advance for any help

Found the answer!!

Seems the fios router allows you to setup VLAN's for each of the 4 ports...thus creating a subnet as needed. 

ie.

port 1 assigned VLAN1 with an LAN IP of 192.168.10.x

port 2 assigned VLAN2 with an LAN IP of 192.168.20.x

port 3 etc...or just leave as is for the normal fios setup

port etc.

Depends on the brand and model of the two routers. What are they?
