Just a heads up; the recent firmware update, 1.0.04.28, causes multiple devices to be blocked if you have configured at least one device to be blocked.
The UI responds with an invalid password message at authentication.
Have you seen other reports of this? I haven't. Yet.
Did you reset the router to factory settings after the firmware flash?
New firmware sometimes introduces changes that are not compatible with the old configuration.
So while it isn't guaranteed to fix problems a factory reset is the first thing to try if you have issues with new firmware.
This is a nuisance because you then have to reconfigure the device all over again.
You can backup your settings before you reset and restore them later. But that may just bring back the fault. Then again, at least you will know if the reset fixed the problem.
