Yep! The Gen 3 router is compatible with the Gen 2 system, but it's a little awkward because you have to keep the Gen 2 router in place. The Gen 2 router continues to provide power to the dish. Basically what you do is treat the Gen 3 router like a 3rd party router:

- You will need the Ethernet Adapter if you don't already have it.
- Connect the Gen 2 Ethernet Adapter to the Gen 3 router WAN port (left most dish port) with any Ethernet cable.
- In the Starlink app, turn on bypass mode for your Gen 2 router. It's in Settings > Router > Bypass mode.
- Plug in the Gen 3 router power supply and give it 5 minutes to boot up.
- Connect to the "STARLINK" WiFi network on your phone.
- Open the Starlink app and configure your WiFi network name and password.
