My deskside machine has wired ethernet to my router. It has
forever been the case that Windows latches onto the network at
boot every time with no problems until now. I cannot think of
anything I have changed. Perhaps this is the result of an
update, but now when I boot the machine the network connection
does not take place and I have to fiddle with disabling/enabling
the adapter a few times before it does connect. That's not a big
problem, but I'm curious what might cause it. ...and it is not
quite consistent - about one time in five it connects instantly
just like it used to. Hardware diagnostics don't show anything.
