I get that T4 missing uplink channel even after the update as well but its only once in a while after a reboot. Another quick reboot corrects it.
What's strange for me is that I don't see the T4 errors. I do see a T3 error on the reboot before the correct time is established. That may be related. You would think missing one out of three channels would have an effect on the uplink speeds, but I'm getting 7+ mbps.
