I am relying on wifi. However, I don't think that's the issue, because I can access the Blink through the network even while it is doing the the reset.
I talked to a different Ecotality tech this morning, and he clearly had a much better understanding of the device. He said a few interesting things:
1) I have an older hardware version, manufactured 10 months ago (Rev XXX3, March 2011); and he could tell that it had not been installed before but that it may have been used as a test version by the engineers.
2) Anyone currently having issues with their Blink that may be software related, must wait until the 2.0 firmware is finalized in February before they will spend any service time on it. They will not push the 2.0b firmware to units on request; only if the engineers want to test it on that particular unit.
3) Frequent starting and stopping of the Leaf's charger won't cause any damage. I'm fairly sure he's not qualified to say that, and Ecotality certainly can't be held liable if he's wrong
4) My Blink didn't phone-home to Ecotality for 2 out of 4 days, even though it was connected to the LAN. I tested the LAN connection each day by connecting through it's intranet interface. Since it is phoning-home some and the network test is successful, it doesn't appear to be a firewall issue. I am currently running a port-scan to see if I can determine what port to open up in the firewall just in cast that is the problem.
5) The unit is evidently rebooting, the unit shows that it's only been "up" for the past 9 hours.
5) Usually these symptoms indicate a problem with the cable or J-plug connection, but in my case the hardware all appears pristine.
6) Barring #5, he suspects that the problem lies in the upstream electrical connection, possibly a leaky ground or fluctuating voltage. This is my vote, although I would hope that the electrician tested this all at installation.
