Connectivity went down. It has returned, but the red light is on with the
MISSING_OR_WRONG_PACKET(-9) error.It's in a simple home network of Aruba AP22 (PoE) ↔ Cisco C1000-16P-2G-L switch ↔ Cisco ISR 921-4P router ↔ Arris TM1602AP2/TW Cable Modem.
Additional wired end points connected to the switch. No other 802.11 WAPs or routers.
Switch
Router handles DHCP, DNS (via ntp.org), and NAT.
The only config changes this morning were on an ACL on the router's cable modem facing interface, which should not affect anything.
