I'm currently running a desktop and multi monitors connected through an APC battery back up system but it occured to me that I also need a battery backup for my router so that's next on my "to purchase" list. I would also like to install a secondary internet connnection from a different ISP provider. I now have DSL and so would add cable. Is anyone familiar with the hardware / approximate costs required to accomplish such a feat? And could you suggest any specific manufacturer and models? Many thanks
