3. Run `Get-DeliveryOptimizationPerfSnap` from an elevated PowerShell window on the second device. The **NumberOfPeers** field should be non-zero.
4. If the number of peers is zero and you have **DownloadMode** = 1, ensure that both devices are using the same public IP address to reach the internet. Open a browser Windows and search for “what is my IP”. You can **DownloadMode 2** (Group) and a custom GroupID (Guid) to fix this if the devices arent reporting the same public IP address.
