After I figured out he bought the wrong ones and before my son in-law returned the 5201 we did some outlet testing with a Mini. When we picked a circuit that was on the same pole as the Roamio, the XAVB5201 worked perfectly and as well as the 5101. So make sure you get the XAVB5101 with the GigE port. The link you cite is correct.
I believe i would need 3 (one at the router and two at each of the tv's with the mini). Do you know if they make a single add on rather than having to purchase the two pack twice if I decide to go this route?
I don't believe they sell them as singles. I've never seen other than a two pack and that is how I've bought them (I have 4). You can always use the extra one to connect your main computer network and thus extend your house Ethernet network around your house. That is what I do. I have an AV500 upstairs attached to the main network switch. This allows my Roamio to communicate with the TiVo server I set up for transferring programs back and forth for off-line storage. In my case the Internet router is upstairs also and plugged into the main switch so this PLA arrangement is also needed for the Roamio to access the Internet. At my media center, the AV500 connects to an 8-port GigE switch (GS108). The Roamio and all my other AV components that need a network connection are plugged into that switch (Roamio, WD Live-SMP, BD Player, Wii, HDHR2 Network tuner, plasma TV). I'm sure you will find a use for the 4th adapter.
If it makes you feel any better, when I bought my first pair of AV500's a couple years ago they were well north of $100, so they have come down quite a bit.
