AX2700/CAX30 DHCP stopped assigning IP addresses to devices
Device: CAX30 Cable Modem Router
Firmware Version(s): 18.104.22.168 and 22.214.171.124
Issue: DHCP stopped successfully assigning IP addresses to devices both wired and wireless unless the device has been setup to receive/request a static IP.
Expected: DHCP should assign an IP to any device that requests one if it is not already assigned to a devic and is available.
Attempted Solutions: Restart modem; Factory reset and reconfigure modem; Restart device(s); Reset devices network settings (forget network, reset netowrk settings)
Workaround: Set a static IP request from the device if possible (some IOT devices do not provide an interface for requesting a static address and so this does not work for them).
Other possible workaround I have not tried: Setup a new network SSID instead of using the original SSID for wireless devices. This was mentioned in another thread of a way to get wireless devices to be successfully assigned an IP, but I do not really want to do this because of the number of devices with setttings to reconfigure, and I think it was reported the problem eventually came back for the new SSID where devices could not successfully get a dynamic IP assigned from DHCP server.
