(Aren't you one of the people that were trying to convince me things were so much simpler and easier on Linux? And now it's taking a committee to slowly over weeks get your one xeon phi box operational?)
Long-cable is likely what I'm gonna need to do ... but router is hidden behind a large sofa, with end tables at sides and rug+coffeetable in front, so getting physical access to it will require moving some furniture.

Re. other-work, the hour-per-day-max I've budgeted for this is not eating into my worktime, been sacrificing other internet activities, mainly lightening up my daily newsreading. And what do you think I intend to use the KNL *for*? Lots of cores, not a lot of memory, just the 16GB fast onboard RAM ... how much RAM would a really deep p-1 stage 1 run of F33 need? Mersenne-mod p-1 for v20 of course has first priority, but the front and back ends are more or less the same, just for M(p) one supplements the stage 1 prime-powers product with 2*p, whereas for F(m) one uses 2^(m+2).

Re. your spoiier: been very happy with my Ubuntu installs on other systems. CentOS, alas, seems to have been packaged by sysadmins, for sysadmins - not packaging the GUI and all-the-packages-needed-to-use-wifi with the basic install image, as e.g. Ubuntu does, is unforgivable in user-friendliness terms. But being annoyed at the folks who put together the distro is not helpful from a practical standpoint.
