I have had so much trouble with comcast high speed internet that I ordered DSL as a backup a few weeks ago... it has already paid for itself for the next ten years. I would like to acheive 100% uptime. I have an abit IP 35 pro motherboard with two gigabit ethernet connections. The problem is I believe Windows XP only receives data from one connection at a time and will only switch over after one of the connections goes down. The problem is that even during this automatic "failover" there is a few seconds of downtime. Not really a big deal but it screws up my Ninja Trader to IB connection and causes me to have to restart Ninja Trader and IB!!! This is what I want to avoid. Anyone have something set up to acheive this level of redundancy. It looks like I could get a dual WAN router but are there any other solutions anyone can think of?
