5276 does appear to stay connected - it tries to update right away but just X'ing out clears that.
Prior tests on this new profile(s) would have been using whatever build is the one linked on the website.
Trying my damndest to do the weirdest possible unplug/plug-in, always goes back to connected.
Going to try re-joining domain, see if that "broken" profile works with that build, post-ASUS uninstall.
