I have just hooked up my new 1.5Gb internet connection and obviously the 1Gb ports will not fully utilize the speed that the connection will provide.

I want to have 2 lines to my modem/router that is currently in bridge mode (from my research the device supports multiple pppoe connections) and I haven't the slightest idea how to configure it...

any help would be great

have a look at the wiki: https://wiki.dd-wrt.com/wiki/index.php/Dual_WAN_with_failover

You will not get over 800 Mbit/s LAN-WAN with this router anyway. Not even the WRT3200ACM will cope.

Only capable router is Netgear R9000 which have a 4 core processor and a SPF port where you can put a 10 Gig interface.

What type is your modem? Is it connected to a fiber cable?

Looks like you got a rush of blood when you got a 1.5 Gb/s WAN connection, and realising that your modem only has 1 Gb/s LAN ports, thought it would be a neat trick to split the incoming WAN speed across two devices. What you failed to take onto account is that your WAN connection comes with one IP address, and you need a router using NAT to share that IP adress amongst all your LAN connected devices. So you need a router as your first device and to provide those speeds you would probably need a SFP (fibre) connection between your router and the modem.

There are no home routers with 10 Gb/s WAN ports or SFP WAN ports (the Netgear R9000 comes closest with one. SFP LAN port) so you would need to find a commercial grade edge router, with prices starting at over $2k (and no DD-WRT support).

Unless you have LOTS of megabit devices on your LAN you would be unlikely even notice any improvement

My ISP allows for multiple PPPOE connections with multiple IP addresses and my thought process is if i can get dual WAN running, if i am say downloading something at full speed of my NIC on one machine the load balancing will kick in and allow other devices to utilize the remaining .5Gb of bandwidth that i am allocated (my wifes Netflix will still work fine if i am downloading something at full speed)

I am fully aware that no one device will get 1.5Gb of bandwidth at any one time due to consumer hardware limitations
