CC not working. advice please
#1  patray 06-28-2013, 05:48 AM
I cannot get the CC app installed yesterday to my Nexus 7 to work. I have followed the instructions re the IP addresses. Before I spend any more time could someone please advise me if the following is the problem.

I downloaded Calibre to my laptop in the UK where I live. I downloaded Calibre Companion to my Nexus in Cyprus where I am on holiday. Is this causing the app to fail? Will my Calibre only work with the app in the UK? Sorry if this is a silly question to the more tech savvy people but I want to rule this out. If this is not the problem some help in getting the app to work would be appreciated, thanks, Pat

I shouldn't think is a problem. Check out the Sticky thread, Calibre Companion Android App: Information, Change Log, and FAQ, for more guidance.

You need to do more work at the HOST end.
CC (and almost everything else today) works on a LAN.
Your Router/firewall separates your LAN from the WAN for safety and security (and because your ISP only allows 1 IP on a connection)

You need to have done:
Assign/reserve a fixed (LAN) IP for the host

Set 'Port Forwarding' (allows a WANside port request to a preset host-server) to the designated IP

Setup a method for obtaining the current WAN IP of your router. (DynDNS type service, ISP provided Static IP, A neighbor with access to your router/WAN that can query it and tell you what it is right then

I assume you have your laptop with you while you are on holiday, and that you are attempting to use the hotel's Wi-Fi to make a "wireless device" connection. If this is is the case then it will almost certainly not work. Reason: the vast majority of hotels that offer Wi-Fi block connections between devices in the hotel. This is done for security. They do not want any possible responsibility for someone getting their computer hacked by the person in a nearby room.

To do what I think you want to do, you would have needed to set up a calibre content server on the internet before you left in the way theducks describes. It might be possible to do something with VPNs (virtual private networks) but the complexity is very high.

If you purchased CC to solve a specific problem while on holiday and find you can't then you might want a refund, which we will be glad to provide. Use CC's help dialog to make the request.

If you are using your Laptop in the same location as your Tablet, you might be able to bypass the hotels policy (but then, why not just side load).

You might be able to set (carefully) your Laptop to allow ad-hoc (the default is infrastructure) connections. Be sure to set your firewall to only allow incoming from your intended device(s)

Thank you for replying . I am not in a hotel. I am in my home here. I'm afraid the advice given is to advanced for me and I don't understand it. I will look at the sticky and see if that helps. Thanks again, Pat

Do you have your laptop running calibre with you in Cyprus, connected to the same home Wi-Fi as your tablet? If so, the "how to connect" FAQ answer should help. If not then there isn't much you can do until you return to the UK.

There is no reason to believe his laptop and Tablet aren't in the same room. I think your directions in post three may just be clouding the issue. Hopefully the OP will be able to clarify his position and work things out.

You make a good point. The OP confused things a bit by saying Loaded Calibre in the UK. I just assumed he left the rig running in the UK since Calibre (and CC) are not listed as having any regional limits
