after High Sierra 10.13.2 Update with Fusion 10.0.1 I get Unidentified Network on Windows 10

Hi,

after the last update of OSX.

I start my Windows 10 virtual machine on Fusion 10, at the beginning it work correctly then, after a while, I get Unidentified Network error message in the windows network adapter.

The error persist to the a simple windows restart operation.

The only way to solve the problem is to completely quit of fusion program, at the next start the network works fine for a while.

I use wifi in my Mac machine and the network configuration on fusion is the default "Shared with my Mac".

before the update I used HighSierra 10.13.1 and everything worked fine.

any suggestion?

Thank you

Domenico

Did this work long term for you sergiorru​ or did the problem come back after uninstall / reinstall?

Hi elgwhoppo,

Yeap, but some times after sleep restart of my MacBook Pro (closing the lid and opening again) the network adapter appears with "no internet status" but when disable and enable the network adapter over vm settings this come back to work again.

Best Regards!

Greetings -- I too had the same issue -- and I have been able to solve it, without using the Terminal  / command line  [cli].

I agree its a VMware bug  that needs to be fixed.

Here is how to solve it, all within  the GUI.

   [as I am traveling and did not want to try and download and reinstall of of VMware Fusion, glad this worked.

  And yes, the Terminal CLI scripts listed later in this thread had same error for me -- they were not of use]

For the Index and Google to help others -- VMware Fusion 10 , Mac OSX High Sierra, Win 7 x64  VM  [Windows 7 x64 Guest]

Go to your VMware Main Prefences Page.

Inside this Prefs page, there is a network tab, go to it.

You will then want to authenticate to unlock the "Lock" Icon.

   [this is your Admin password to your Mac]

You will then be able to add a custom network profile -- it will create one, and you simply need the standard defaults.

Since I need the NAT to do my job effectively, I simply added a new NAT, with all the defaults checked [shown].

   No need to be a network guru.

This new profile--  you will then select in your individual VM's in their indvidual network settings,

THEN the DHCP will work for them without a problem.

Basically this procedure creates a new profile that works more reliably than the prior default, which became problematic

after the Fusion upgrade and OSX upgrade   [VM did not change; vanilla Win7 Sp1]

Looks like my solution is not fully viable -- I still keep getting disconnects, even after implementation, but mystified as to their cause---???

No change in ethernet, Mac network is 100% stable and viable -- but Win7 VM says "unidentified network"...

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --configure

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start

Worked for me

I have this bug too. I encountered it first when switching a VM from Bridged to Shared network. The guest would not be issued an IP, even after rebooting the guest. Only stopping and restarting VMWare Fusion fixed the issue.

An hour or so later, the network was lost again. I was able to suspend the VM, restart VMWare Fusion, and then resume the VM and it picked up an address.

Given that I've had this issue for a long time and no resolution seemed forthcoming, I contacted VMWare Support. The agent walked me through a process of a clean reinstall, and after running through this process, I can now say that where I was experiencing the issue before, I am no longer able to replicate it. Here's the clean reinstall steps:

1. Download and install AppCleaner from FreeMacSoft.

2. Run AppCleaner and run the cleaning operation on VMWare Fusion, taking care to check all options to remove.

3. Run Disk Utilities and run First Aid on the main volume (Macintosh HD by default). Note on some systems, this may make your system unresponsive for minutes to hours, so use with caution and never while multitasking.

4. Restart and reinstall the latest VMWare Fusion.

I hope that helps others that may have encountered this situation.

Hi,

I was having the exact same problem but i simply followed the below steps and its working perfectly

Problem Statement

===============

VMWare Fusion 10.0.1 installed on macOS 10.13.6 running a Windows 10 VM. Windows VM does not have internet connection, specifically the error "A valid IP address isnt assigned is shown" in the network troubleshooting guide (windows 10)

Fix: Consists of 2 steps. This assumes that your Windows VM is already running when you apply this fix. (If it isnt, then perhaps Step 2 isnt needed, i have not tested that scenario.)

STEP 1  - On MacOS - open terminal and type

==================================

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --configure

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start

STEP 2 - Inside your Guest VM (Windows 10)

==========================================

Reset your network adapter. In the Guest VM, go to Settings > Network & Internet > Status. Here, it should automatically detect that there is a problem in your network configuration and offer you to "Troubleshoot Problems". Either you can use this feature, which will essentially reset/restart the network adapter for you, or, alternatively, you can go into Control Panel > View By = Small icons > Network and Sharing Center > Change Adapter Settings > Here, find the Ethernetxx adapter which corresponds to the Gigabit Ethernet connection. Then simply select it, choose "Disable this network device", and once its done Re-enable the network device. Now, the DHCP (macOS side) should be able to assign your Guest VM a proper IP address and your problem should be solved.

My scenario is not exactly the same  but I'm posting this in case it helps someone else.

Fresh VMWare Fusion 10.1.3 install on High Sierra 10.13.6

Windows 10 guest, migrated from VirtualBox to VMWare

No internet in guest, not using NAT or Bridged, despite trying all the manual suggestions in this thread.

VMWare support removed my only network adapter:

Shut down guest, Settings > Network Adapter > Advanced options > Remove Network Adapter.

And added a new adapter, Settings > Add Device > Network Adapter. Changed from NAT to Bridged. Start guest and the new adapter worked flawlessly.

I'm embarrassed that I didn't try this before opening a support ticket. Shout out to Praveen at VMWare support.

Good luck.
