Quick answers by symptom
| Symptom | Most likely fix |
|---|---|
| Software can't see adapter | Driver reinstall with admin rights; avoid USB hubs; check RP1210 device selection in the app |
| Connects, then drops | Disable USB selective suspend; use wired (not wireless) for long sessions |
| Activation rejected | Windows Pro required on most OEM tools; portal email must match purchase exactly |
| Slow performance | SSD + 16GB RAM is the real baseline for PTT/INSITE |
| Truck won't communicate | Ignition on; verify green vs black 9-pin; bypass telematics splitters |
