Another problem for me:
I have 932L and 2332L connected to my router over WLAN. I need to use My dlink application in my Nokia Lumia 920. Both works fine, ONLY IF my Lumia is connected to same WLAN. When I'm in 3G network, the 2332L will always timeout (with error code: 1_0_2_3_0_FFF) while 932 works fine in 3G. One difference is that 932is next to router and 2332L is outside, but not far away (~5 meters, only one door between (where is window).
I can connect to 2332L with my PC that is in the same WLAN as the camera.
Any idea what is wrong here? Should I change some WLAN settings in the camera, or how to check if F-secure or Firewall will disable it?
