    The final digitalWrite() sets Ethernet's SS true but comment may be wrong. Seems like that line of code is supposed to be handled by the Ethernet lib

    I read that the Ethernet library's begin() function can leave the slave select pin low (true). Perhaps that's fixed in the version used for Teensyduino (5100/5200 chips), but this code won't hurt

    For the 5100 yes, but the other SPI device is present, and uses a different pin for slave select.

    If you use the Teensyduino SPI library, I believe that it assers/deasserts chip select. As I recall, you'd have two instances of the SPI library code, each initialized (.begin) with a unique CS pin...

    chip selects vs. SD card vs. WizNet board vs. the SPI library for Teensyduino (which has code to emulate the AVR's SPI)... is this sorted out OK?

    Try configuring the Wis820 to use an unoccupied LAN IP address and matching mask and gateway IP in your network, rather than DHCP. And static IP for DNS such as 4.2.2.2.
