RBR10/RBK13 and 2 Satellites no performing as expected.

Thanks for the response! The material between the basement and 1st floor is just wood. There is probably some duct work between 1st and 2nd. Since my original post, I've tried moving the 1st floor satellite to a guest bedroom over the garage, so now it is configured like an upside down L, with the bottom of the upside down L being the router, the middle point being the 2nd floor loft, and the end point being the guest bedroom (also 2nd floor). The guest bedroom is is trying to connect via hub-spoke to the router, but it should definitely be connecting via daisy-chain, which I do have enabled. Do you know if there is a way to force it?

Edit: Since this reply, they have daisy-chained themselves. This is probably the best configuration for my home. I didn't actually measure the distance between points before and I was grossly over-estimating. Writing this post forced me to break out the measuring tape, so I bet this will work well now.
