Attached a wireshark capture screen:
- close all app on iPad, iPad IP is 192.168.1.11 (DHCP)
- start capture on PC, PC IP is 192.168.1.120 (static IP)
- start Kinksy on iPad, Kinsky found foobar2000 and Asset UPnP servers, couldn't see both PC and QNAP minimServer
- stop capture

As you can see, my PC receives SSDP fine, and I suppose foobar2000 and Asset UPnP responding fine.

Also attached a netstat -nab capture. There are only 4 programs bounded 1900. They are 3 foobar2000 (Yes, I have 3 foobar2000 instant on the PC!), and a Asset UPnP, but no java for minimServer.

Both PC and QNAP minimServer still work fine if I wait long enough for their 15mins apart "alive" message.

Thanks very much for producing this detailed information. I'll report this problem on the ohNet forum.

Is it always the case that both the PC MinimServer instance and the QNAP MinimServer instance stop listening to port 1900 at the same time? This could be important for discovering what is causing the problem.
