I have 6D and trying to pair it with my computer running Windows-8. It worked once, but after that pairing utility never finds the camera. The C:\Program Files (x86)\Canon\EOS Utility\WFTPairing\EOSUPNPSV.exe is taking around 40% of the CPU cycles, and stays there.
I reset the camera WiFi settings and now its in the last stage of pairing.
I see this on the camera:
EOS-C78751 pairing in progress. Start pairing software on computer.
On the computer WFTPairing is running, and as mentioned taking huge chunks of CPU. Firewall turned off on my computer. I checked with a UPnP spy utility, and can see 6D on the network, but the Pairing utility seems to not. I tried reinstalling EOS utility multiple times too.
I too am having a problem with EOS Utility 2 and WTF pairing for the 70D. It is working ok to android pad and smartphone however, if I even install EOS Utility 2 it causes my BT home hub 5 to repeatedly reset, Uninstall the software and stability is restored.
I have repeated this many times and it is absolutely linked to installing this version. The previous version of EOS utility supplied in the box with my 700D works fine, but of course will not recognise the 70D.
I have tried the solutions above, to no avail.
I get a lot of errors in the logs when it is happening that it can't resolve DNS server, and no internet until the utility is uninstalled. On a couple of occasions I have also had error messages appear indicating an IP address conflict.
I am currently running perfectly stable but without EOS utility 2 (2.14.0) and WTF and using SD cards to transfer the images.
I am using Windows 8.1 (64bit)
There is a definate bug in this version of the software that clearly causes issues with certain PC configurations/wireless hubs.
I have seen numerous other posts along the same lines on this and other forums, so this needs a quick fix please. It is one of the major selling points, and it clearly does not work as well as it should.
Unfortunately Canon is not responding, and the problem(s) still remains. I'm seriously looking at other brands now, since Canon tends to release products that are not suitable for delivery more and more.
