Guys, the 5GHz wifi channel is there and available, but it's only single channel and so limited to (theoretical) 54Mb/s. The 2.4GHz is fine at 140Mb/s. I've been used to the TT Hub providing bonded(?) channels for 1400Mb/s on the 5GHz band, so maybe it's just that it's older and only uses single channel. If that's the case, so be it.....
p.s. Stuart, any comment on the fw version?
