So I'm watching my TV and all of a sudden all goes blank. Look at router and all lights are off, then lights start flashing and picture comes back, for about 3 minutes, then the same thing happens. I go in to router settings and discover that you have "updated" firmware to 1.21t from 1.16t.
PLEASE could you roll me back to 1.16t as this is exactly what I had on 1.20t. Since the rollback to 1.16t then I have not had one dropout until this new upgrade.
