[vpn-help] failing with WLAN connection on Win7 x64 [Shrew 2.2.0]

[Thorsten Albrecht]

Hello,

Shrew VPN 2.2. does not work with WLAN 0 on my Windows 7 x64 notebook
Lenovo T510. With ethernet everything works fine.

WLAN uses the following device: Realtek 11b/g/n  Wireless LAN Mini-PCI
Express Adapter II.

The vpn profile is fine, it works on other systems, too (connection to
a VPN router Lancom 1823).

Is there something more I could try to get it work? I tried to
disable/enable the windows firewall but this has no effect.

Thank you for your help and best regards

Thorsten
