Cannot get hyper-v network connectivity in guest over wifi RRS feed

  • Question

  • I'm running an Ubuntu VM under Hyper-V. Access via an ethernet hyper-v switch works great.

    The system is a laptop, and the host works fine with wifi.  OS is Win 10 pro insider/fast build 14942

    I've created a wifi virtual switch in hyper-v, and assigned this to the guest. I also have an ethernet, and host-only switch. I can see all 3 virtual network interfaces in Ubuntu. Only one (the local only) has an ip address (hardcoded)

    I now have
     - Wifi - Enabled, Bridged - Intel Centrino (R) Advanced..... [no properties visible]
     - vEthernet (wWifi) O2 Wifi Hyper-V Virtual Ethernet Adapter  [as usual most "uses" are selected except multiplexor, hyper-v]
     - Network Bridge - connected - Microsoft Network Adapter [only "Wifi" selected] and only Microsoft MAC Bridge, Microsoft LLDP, Hyper-V Extensible Virtual Switch ]

    In the guest "vWifi" is the third virtual adapter connected. "eth2" is showing as up, no ip, though there are some Rx packets

    Only MS firewall is installed

    I know I could consider alternative approaches - I have a private network running fine, so could do regular forwarding on the host. I could also try NAT support though this seemed a little flakey

  • Sorted.

    User Error of course. Hyper-V was working perfectly. For some reason I'd changed the config of NetworkManager in the Ubuntu guest -- so it wasn't even attempting to get an IP address.

    Duh. Hopefully this silly mistake of mine may help others. Check the obvious ;-)
