Had some problems being unable to resolve psgallery due to proxy, unregistered psgallery and trying to register it again:

PS C:\> Register-PSRepository -Default -Verbose
VERBOSE: Performing the operation "Register Module Repository." on target "Module Repository 'PSGallery' () in provider 'PowerShellGet'.".

that seems to have no effect:

PS C:\> Get-PSRepository
WARNING: Unable to find module repositories.

Registering internal repositories works fine:

PS C:\> Register-PSRepository -Name "test" -SourceLocation "http://artifactory.company.net/artifactory/api/nuget/psgallery" -Verbose
VERBOSE: Performing the operation "Register Module Repository." on target "Module Repository 'test' (http://artifactory.company.net/artifactory/api/nuget/psgallery) in provider 'PowerShellGet'.".
VERBOSE: The specified PackageManagement provider name 'NuGet'.
VERBOSE: Successfully registered the repository 'test' with source location 'http://artifactory.company.net/artifactory/api/nuget/psgallery'.
VERBOSE: Repository details, Name = 'test', Location = 'http://artifactory.company.net/artifactory/api/nuget/psgallery'; IsTrusted = 'False'; IsRegistered = 'True'.
PS C:\> Get-PSRepository

A bit of a search turned up this:

Looks like you just gotta define the default proxy settings for WebRequest. 🙂

Thanks that was what I was missing, I've also had to provide credentials:

[System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials

and the PSRepository registered successfully, still I think

Register-PSRepository -Default

could be more helpful and throw some kind of error when it is unable to register.
