I'm not an expert as I'm fairly new to Tivo but I have the same device setup as you described ( a roamio base and a mini)......you say that you have the roamio on the 5ghz wireless? that very well could be your problem.....both your roamio and mini need to be connected via MoCA or via ethernet in other words hardwired and NOT Wireless..... here is how mine is set up: I purchased two action tech MoCA adapters from Tivo; I hooked one up to my cable modem/router(gateway) and the other to my Roamio Base......all I had to do with the mini is just hook the Coax into the MoCA port on the back of it...I'm going to assume that your cable modem/router isn't one that already has MoCA built into it such as a Verizon Fios? Here are some diagrams from Tivo's website that can help
Also on your mini after you have connected your Coax make sure that you go into network settings and do this:
Set yours up like those diagrams and it should work.....let us know if you're able to resolve your issue....
