Canon WFT Paring tool - use with caution!

So every time I start up the WFT paring tool to pair my 70D, the result I get instead is a unstable wireless network. It looks like the Canon UPNP poller goes crazy and hits the network so hard with UPNP queries looking for a camera that it overwhelms the wireless network. Poor programming. Sadly I thought it was caused by a bad router and replaced my router, with the same results, until I found the thing still running in the background on my desktop.

I too have experienced a massive surge in ethernet traffic which all but crippled my router. I replaced it with a spare only to have the exact same thing happen. I traced the fault by unplugging everything and plugging things back in one by one.

I've not conclusively identified the WFT tool as being the fault, but reading this...

It is, once I had isolated it I did some testing, with it on, total wireless failure, with it off, no issues. Watching the process it is eating 10% of my CPU - an i7, apparently just generating broadcast traffic. I didn't fire up a sniffer to totally verify the traffic load but it is clear that with it running it hoses my network, with it off everything is fine. It should only query every second or so, whatever they are doing is insane.

Would changing the channel on your wireless help?

Nope. I am actually in the clear here on my channel, and this isn't an issue of channel congestion, it is an issue of excessive broadcast traffic saturating the network and the router's ability to handle it.

Not to bring up an old thread but not sure if anyone came up with more info on this. I to am having this issue now. I didn't have an issue b4 but now I do. But, It only does it when I'm connecting to my laptop that I just got. My other computers are win 7 but the laptop is 8.1. When I go to connect to the laptop the router D-Link seems to stop all activity.

I've never seen this issue, but then I've not used Windows 8 for this either. Only XP and Windows 7.

I found allot of other ppl with the issue. It is a windows 8 issue. The fix seems to run the program in administrator mode. It seems to work that way but if yo don't it will cause the router to crash.
