      Subnet mask is likely set incorrectly.

      Are the IPs static, or distributed via DHCP?

      It sounds to me like the devices are configured with the wrong subnet mask – likely configured as a /24 rather than your desired /21.

      If you review the configuration on one of your devices (using the network configuration GUI or ipconfig / ifconfig depending on OS), you can confirm this suspicion.

      Also check to ensure your DHCP server is handing out the correct subnet mask.
