How to solve connection issues

Hi,

I am using Cubase AI6 with my Motif ES6 and Rack XS over FW16. Since I have also iPad2 and Yamaha applications, I saw very interesting possibilities with Cubase iC Pro remote control.
I have bought it from AppStore and set up as it is said in manual. I have installed SKI remote (latest version) enable it as a device in Cubase AI and set both PC (Win7 32bit) and iPad to the same wireless network.
iC Pro recognizes both Cubase and my computer (I could see under connection Cubase AI @ MYLAPTOPMSI) but connecting last about one minute and stops.
I have read all instructions for Windows and check everything:

  1. Bonjour service is running
  2. Cubase AI is enabled in Windows Firewall.
  3. All other network adapters (LAN, virtual WiFi) are disabled except Wifi.

I have even tried to set ad-hoc network between PC and iPad. Network works fine, but iC Pro still not. Then I have read that maybe on some Win PC’s problem could be if WLAN security is other than WEP. Mine was WAP-Personal and I have changed to WEP. Still nothing, situation is completely the same.
Does anyone have similar problems?
P.S. Provided link for troubleshooting article don’t work!
