The Canon S110 comes with an optical disk containing a software bundle for Windows (and of course nothing for Linux), including an utility for connecting to the computer through WiFi.
Also I think worth noting is that in Windows the transfer process requires Media Streaming and Network Discovery to be turned on. I think this would be key points for enabling photo transfer on Ubuntu also, but I cannot find [the equivalent of] these options anywhere.
This link explains the process for Windows.
So the question is how can I transfer my photos from the camera to my Ubuntu PC over wireless?
I love the wireless option on the Canon S110 and have been using it intensely before switching over to Linux, I don't like to mess with cables. Anyway, I already lost the original cable. Also my PC has no card reader.
I am using both Xubuntu and Mint 16 XFCE.
