Yes, I tried it twice

All three have been known to prevent CC from talking to calibre.

None of those, no. And I've checked all the firewall settings as mentioned in the FAQ.

Belkin 4365e8

1) Start calibre's content server (Connect/share, Start content server) on port 8080 (the default). Using chrome (the browser software) on your device, attempt to connect to calibre's content server using the URL http://192.168.2.20:8080/ (ip of machine running calibre). If that works, then we know that the problem is somewhere in CC or is a port-related firewall issue. My guess is that it won't work, in which case we are left with both security software and guest mode.

Yep, didn't work.

Assuming that the computer running calibre is connected to the home network using a cable, if you can, also connect this second computer to the home network by cable and run the test. If it succeeds then we know the problem is guest mode.

The computer running Calibre is a laptop and is not connected to my home network using a cable. Does it need to be?

ping 192.168.2.13

where the 192 ... is the IP address of your device. If you get something like

Reply from 192.168.2.13: bytes=32 time=1ms TTL=64

then the problem cannot be guest mode, and almost certainly security SW on the computer running calibre is the problem. If you get something like

Reply from 192.168.2.20: Destination host unreachable.

then the problem is probably security SW but still might be guest mode.

The ping was successful.

I quite simply cannot get the laptop to start in Safe Mode with Networking!
