For what it is worth, I had a smoothieboard I was trying to connect directly to my computer, and no power on earth seemed to be able to make it work reliably with DHCP. I statically configured the IP, and it connects every time with a direct connection. Never did figure out that issue, just leaving it static now that it works.
(It would talk via DHCP about one in 10 times I powered it up).
This is also a "For what it is worth" addition...
Yup, this connection is static, so clearly not that issue.
On my post Pi reboot test I started by powering off my computer, then "draining it" by turning off the power supply switch then hitting the power button which gives a click from the speaker. Only then do I turn the power supply back on and again hitting the power button to power up. Interestingly this *did* then find the NIC to work fine. Problem solved?, nope. I then rebooted to see the problem still there. This did allow me to test my new desktop icon to run an ssh over to the Pi (once I see WiFi up). The script (ssh pi 'sudo mii-tool --reset eth0') works fine. So I am done with this, I will just watch to see if something mysteriously fixes it eventually. But I will be happy to test anything else people might want me to try.
Thanks all for the help.
