ok guys,
i had the same problems. after many many hours of trying i solve this problem. here is what i did:
1. i disabled the windows-firewall for my WLan-connection on my notebook and suddently everything worked fine .
2. enabled the firewall again and opened the system for ports 990,999,5678 and 5679 (AS ports). BUT: DIDN'T WORK
3. disabled the firewall again : WLAN ASYNC WORKED AGAIN
4. tried to open the ports under firewall -> extended --> "Allowed services" : DIDN'T WORK
5. disabled the firewall again : WLAN ASYNC WORKED AGAIN
6. enabled the firewall and opened "file- and printer-sharing" at the firewall settings ---> WORKED!! YEEHAA
deleted all the new port entries i made before --> only enabled "File- and printer-sharing"!
the solution : "File- and printer-sharing" opens NetBios and UDP port 137! Both is needed for a sucessfull sync over Lan or WLan! NetBios --> makes sense !!!
