Hi there,

I have a problem with the Wireless-Network.

On my WLAN-Home-Network it works perfect (internet and network). But not at my parents WLAN-Network (always shows yellow exclamation mark showen on network symbol in windows guest taskbar).
Both use a "FritzBox" as DHCP-Server. The Network devices are also comparable.

When I launch Windows, it shows no yellow exclamation mark.After some seconds it appears.
I tried different things, but nothing worked. I can't get Networkaccess or Internet.

Host: MacOS Mojave (10.14.2), MBP 2018
Guest: Windows 7 Prof.
VB 5.2.22

Network Settings: "Netzwerkbrücke" -> "Networkbridge"
"erlauben für allen VMs und den Host" -> "allow for VMs and Host". Changing "Promiscuous-Mode" has no effect at all.

In NAT-setup it works perfect in both networks ... but unfortunately I need bridge-mode...

Hope you could help me.

Best regards!

Morris

Bridged over wireless don't always play nice. Bridged networking is outside the WLAN specification. Bridging to wireless is not really bridging. The guest shares the MAC of the host and the host does a sort of MAC-NAT translation based on IP addresses. Promiscuous mode doesn't exist in the official WLAN specifications. It may or may not work.

Some combinations of Routers/Access Points, WLAN cards and drivers work, some don't. See: Bridging & Wifi - Supported hardware and add your experience. For example, it works fine in my home, but not in my office. Same laptop, same VM.
