I now have both the Nano and Tetra (yay me), and I went to do the firmware update on both. I connected my tetra to the system that I normally use it with and it connected fine to the internet (via internet shareing on my LAN NIC). Then I tried to the same with my nano, this did require me to go through the basic internet sharing step again. This time it did not work and i cannot get the tetra working again either. I tried on another system with the same results. Any thought on where I messed up? and what is need to run both devices on the same laptop?
