Second one of the RB951G-2HnD seems to have upgraded fine, which makes me think it is the one unit that is faulty. Another 2 to test it on.

Having issues with 5.23 on a RB951G-2HnD. Upgraded from a new 5.22 with default config applied and rebooted. Could no longer access it. Used NetInstall to redo the upgrade, and that got it back up on its feet. Did a restore to Defaults and I was no longer able to access it. I have another 3 RB951G-2...
