I have the standard comcast business modem. I tried to use "Device Control Management > Managed Devices" to block one of my devices from connecting to WiFi from midnight to 6am. That worked, but during that time the device tried to reconnect >1000 times, which resulted in that device being blocked by the modem's firewall, and now the device can no longer connect to WiFi. This pesists is despite me removing that device from the list of blocked devices in "Device Control Management > Managed Devices" and restarting the modem. Trying to temporarily disable the the firewall with "Gateway > Firewall > IPv4 > Custom Security > Disable entire firewall" also had no effect.
"Troubleshooting > Logs > Firewall Logs" contains the line (MAC address hidden for privacy)
Device MAC:XX:XX:XX:XX:XX:XX, 1991 Attempts 2020/6/23 04:58:01 Device Blocked
I'd like to be able to connect my device to WiFi again. How can I do that?
Thanks!
