    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.

    I get the same on my Aruba Instant On Devices and those of all customers.

    I don't think that this is a local issue at your site.

    I think that this is a global problem with the connection to the Aruba Instant On Portal.

    I think that you you may be right about the connection to the Aruba Instant On Portal.  When I relaxed the ACL rules in my router, this problem went away.

    I'm trying to get as close to zero trust as possible.  Do know which Aruba IP addresses need to be white listed?
