I use my personal router with the ultra with no issues. You can go into their box and turn off the wifi router. Then just connect your home router to their box. Been running that way for 4 months. Much better experience.
As I stated in another thread, a simple $20 repeater allows me to use the Ultra gateway router as my DHCP server and still have whole house HD video streaming capabilities. This is just another easy alternative setup that you may consider.
