I have a 2930n with the latest 3.6.3sb firmware.

Im am experimenting with two broadband connections for the first time, I have a BT connection running at Approx 3.5Mbps and a Demon connection running at approx 2.0Mbps.

I have made the assumption that with the correct configuration I can "pool" these connections and effectively get all my network devices to share 5.5Mbps downspeed? Have I assumed correctly becuase at the moment even though WAN2 (demon connection) says it is connected my downspeed seems to be still at 3.5Mbps according to speedtest.net.

WAN2 is connected via a Vigor 120.

Any suggestions greatefully recieved.

Your thinking of Bonding the two which you can't do, however you can load balance which in affect splits the load to the two connections for example if you have 4 computers running PC1 to PC4 and all request pages etc then PC1 will get wan1 and PC2 will get WAN2 and PC3 will get WAN1 and PC4 will get WAN2 and so fourth...

having two adsl / WAN's does help , in my previous setup ( 2830 ) i had two subnets ( LAN1 and LAN2 ) lan1 used WAN1 and Lan2 used WAN2

Thanks Ghostworks for the clarification at least there is nothing wrong with my config.
