Created Unassigned: Validate network connectivity [13489]

Hi , fix validated issue , if Device not connected to wifi internet it will be
System.InvalidOperationException
the validate issue here
Ip = _activeAdapter?.IpAddress.ToString();

_activeAdapter?.DownloadCurrent.Select(ConvertUnit).Subscribe(x =>
{
DownloadSpeed = x.Item1;
DownloadSpeedUnit = x.Item2;
});

_activeAdapter?.UploadCurrent.Select(ConvertUnit).Subscribe(x =>
{
UploadSpeed = x.Item1;
UploadSpeedUnit = x.Item2;
});

_activeAdapter?.DownloadTotal.Select(ConvertUnit).Subscribe(x =>
{
DownloadTotal = x.Item1;
DownloadTotalUnit = x.Item2;
});

_activeAdapter?.UploadTotal.Select(ConvertUnit).Subscribe(x =>
{
UploadTotal = x.Item1;
UploadTotalUnit = x.Item2;
});
it is because _networkAdapterList not valid
so change you code to
_networkAdapterList = AdapterFacade.GetNetworkAdapters();
bool isValid = _networkAdapterList.Any();
if (isValid) {
_activeAdapter = _networkAdapterList?.First();

Ip = _activeAdapter?.IpAddress.ToString();

_activeAdapter?.DownloadCurrent.Select(ConvertUnit).Subscribe(x =>
{
DownloadSpeed = x.Item1;
DownloadSpeedUnit = x.Item2;
});

_activeAdapter?.UploadCurrent.Select(ConvertUnit).Subscribe(x =>
{
UploadSpeed = x.Item1;
UploadSpeedUnit = x.Item2;
});

_activeAdapter?.DownloadTotal.Select(ConvertUnit).Subscribe(x =>
{
DownloadTotal = x.Item1;
DownloadTotalUnit = x.Item2;
});

_activeAdapter?.UploadTotal.Select(ConvertUnit).Subscribe(x =>
{
UploadTotal = x.Item1;
UploadTotalUnit = x.Item2;
});

}
