AC4000 Address Reservation Problem
I have a repeatable problem with Address Reservation on an AC4000 that I am upgrading to from a C5 router. Using the same fifteen IP+MAC addresses used in the C5, Address Reservation and DHCP work fine until I add descriptions to more than one entry. For example, I can add "Amcrest1" to 192.168.1.40, but if I add additional descriptions, DHCP fails completely. I'm not sure which number description causes the failure, but it's somewhere around the fifth. The symptom is no DHCP. My laptop can connect through security to the router but is not given an IP address, and same for my iPhone.
Erasing the descriptions from the IP Reservation entries and rebooting the router usually fixes the problem, but sometimes I'm forced to restore a router-configuration backup that did not have the description entries. If the router backup was made while the IP Reservation descriptions (like "Laptop", "iPhone", "Printer") were present, the router will not work and needs a hard-reset.
Could it be the Address Reservation descriptions, all five of them, take up too much RAM causing DHCP to fail? I just purchased this from Costco on Friday, 2 days ago. Perhaps it defective? I suspect defective firmware since a hard-reset or restored backup will fix it.

Edit: It's the second entry in the Address Reservation table. Doesn't matter which entry, the first is tolerated and the second description corrupts DHCP. Erasing all entries (or restoring a backup) restores DHCP operation.
