    Hi there,
    I'm running a Win7 VM in Parallels 6 (6.0.12106) und MacOS X (10.6.8) an my MacBookPro.
    Recently I had to change my network settings in the VM to bridged networking (standard-adapter) in order to run a remote desktop connection over a VPN tunnel.
    And I had big issues to get it working, as it kept saying "No internet connection" in the VM.

    It turned out, that the VM doesn't automatically receive an IP address from my WLAN router (Fritz!Box 7270) to which the MacBook is connected. When I set up the Windows network adapter to use a fixed IP alternatively it finally worked (I can ping the router and internet access works).

    The strange thing is that DHCP works well when I'm connected to an AccessPoint spanned by my iPhone (connecting to internet over mobile data connection).

    I checked that the router allows new clients to connect to the WLAN, but I'm not sure if this is really relevant, since the VM doesn't use a WLAN-adapter to connect.
    Then I also made sure that the VM has its own MAC address (even with the host's MAC address it didn't work).
    I also tried some of the hints in the trouble shooter like removing+adding the VM's network adapter in Parallels and re-installing the Parallels Tools, but none of them helped.

    Is there anything else I need to consider?
    Do you have any ideas, what might be the reason of the problem?
    For help I'd be very grateful - Greetings!

    Reiner

    PS: I know that it mainly sounds like an issue with the router, but since everything works fine for the host, it seems to be related to the VM... ;)

    Hi, due to the nature of WiFi mode, VM need to use Mac OS's network address. Some routers either doesn't support this at all, or incorrectly implements some standards or just have this ability disabled.

    You could try to assign static IP address in VM (copy the settings from Mac OS). For example if Mac OS has IP 192.168.0.5, subnet 255.255.255.0, dns 208.67.222.222, try to set in Windows VM ip 192.168.0.15 (and copy the other parameters). It is not quaranteed to work, but it can bypass some of the problems/configuration issues on the WiFi router.

    If you wanna access wireless in your parallel VM windows you have to use another external network adapter for your Win7 VM because vm can share wireless network adapter in bridge mode. Also make sure that you external network adapter mount in Win7 VM. Enjoy internet in Win7 VM.
