If one device can connect but another cannot then it is almost certain that one of three things is true:
- The devices are not using the same WiFi band (2.4GHz vs 5GHz).
- One of the devices is connecting as a guest.
- The network security setup is "unusual"
Unless you have a very specific and unusual network configuration the computer running calibre cannot distinguish between 2 devices. Either both will fail or both will work.
One of the "unusual" configurations would be a firewall that filters by IP address, which could allow one device (one IP address) through but block another. Another is using MAC address filtering, either in the router or the machine running calibre.
