Using 2 ISPs to ensure 100% uptime, possible?? Is it possible to use 2 ISPs to ensure 100% uptime? If so, how? 1) Do I need to buy a dual-WAN router to use 2 connections (1 as main; the other as backup)? What dual-WAN router should I buy? How much? Is there any wireless dual-WAN router available (I would like to have wireless connection for non-trading purposes)? My budget is about US$100. I'm not sure if it's enough. I want my router to support ASDL/VDSL/optical fiber connection. 2) If I don't go for dual-WAN router method, what else can I do to use 2 ISPs to ensure my computer 100% uptime? Letting 1 computer to have both connections all the time would be fine. But I would like all my computer have such protection, if possible and is not costly to implement? 3) Let's say I have 2 ISPs connection and one fail. Will my broker software like IB TWS disconnect? Is the computer fast enough to switch so I can still keep logged in? If not, how long do I need to reconnect to IB TWS? Do I need to do anything manually to switch connection? Thanks a lot.
