RBR850 Unable to Obtain IP Address after rebooting Obri - unable to reconnect to SSID after restart

Issue Resolved (root cause still unknown)

Here are the steps that resolved the issue.

1. Changed the DHCP scopes starting address to 192.168.1.100 (was 192.168.1.2)

2. Changed the DHCP scopes starting address back to 192.168.1.2

3. Problem clients were all able to re-attach to the default SSID (Devices Online jumped from 65 to 79)

Furrye38, after reading your message I decided to try the DHCP change that you suggested.  After the initial configuration update to the DHCP scope there was no change.  Several clients, wired and wireless, were still receiving the "Unable to Obtain IP Address" or "Failed to Obtain IP Address" or no error at all, they just could not connect to the default SSID since the initial reboot of the router.  Since the update to the DHCP scope didn't work, I decided to revert the DHCP settings back to their original configuration.  After this change, all of the troubled clients suddenly re-connected.  The Devices Online jumped from 65 to 79.  I'm not sure what the problem was but reconfiguring the DHCP service a couple of times did the trick.  Maybe stopping and starting the service for the change did it, I'm just not sure.

Thanks for the suggestions and the help!
