powershell command to get network adapter connectivity status

Question

I am trying to find a Powershell command that will give me the Connectivity Status for all Network Adapters, for the ones where Connectivity equal "No network access" disable and re-enable the adapter.

First I need to get the correct status, I have tried the following command but it only shows the physically connection. Note the Status for all of them is Up even if the Connectivity status shows "No network access".

Get-NetAdapter -physical

However, what I am trying to target is the Connectivity status as shown in the Network section

Answer 1

Use WMI to do this.

get-wmiobject win32_networkadapter | select netconnectionid, name, InterfaceIndex, netconnectionstatus

Look at netconnectionstatus. You will find a value there. That is the connectivity status.

0

Disconnected

1

Connecting

2

Connected

3

Disconnecting

4

Hardware not present

5

Hardware disabled

6

Hardware malfunction

7

Media disconnected

8

Authenticating

9

Authentication succeeded

10

Authentication failed

11

Invalid address

12

Credentials required

Answer 2

expanding on @postanote answer, it is more efficient to call Get-NetConnectionProfile once and store the results. I also used -eq instead of -match to ensure predictable results. Also if it is more than a 1-to-1 relationship the results could be unpredictable. His answer did not work on windows 10.

#get profiles and adapters
$Profiles = Get-NetConnectionProfile
$Adapters = Get-NetAdapter -Physical

#loop on adapters
$Results = $Adapters | ForEach-Object {
    #get the current adapter
    $Adapter = $PSItem
    #find the associated profiles
    $AdapterProfiles = $Profiles | where {$Adapter.ifIndex -eq $_.InterfaceIndex}

    #output the merged results by looping on the profiles
    $AdapterProfiles | 
         Select-Object @{n='Name';e={$Adapter.Name}},
                       @{n='DeviceName';e={$Adapter.DeviceName}},
                       @{n='InterfaceDescription';e={$Adapter.InterfaceDescription}},
                       @{n='Status';e={$adapter.Status}},
                       IPv4Connectivity,
                       NetworkCategory
}

#view the output in a nice interactive table
$results | Out-GridView

alternative output as a table:

$results | Format-Table

output:
