During discovery, Windows scans 2.4 GHz and 5 GHz channels; receivers within range appear in the **Connect** panel. After selection, a secure pairing (with on-screen PIN if enforced) occurs, and audio/video is streamed. ScreenBeam Miracast operates in **Autonomous Group Owner (AGO)** mode, allowing the receiver’s **Wi-Fi Direct channel** to be fixed away from production WLAN channels. Clients whose Wi-Fi adapters/drivers do not support **Different Channel Mode (DCM)** or **5 GHz** may fail to discover the receiver.  The default channel is 36. ### **Common root causes** - Wi-Fi disabled or Airplane mode enabled on the Windows device. - Client Wi-Fi adapter/driver lacks 5 GHz capability or DCM support. - Miracast discovery uses over-the-air Wi-Fi Direct. Place receivers within practical proximity of user devices (same room) to ensure reliable discovery. - RF interference or excessive AP density on/near the receiver’s P2P channel. - Driver defects/outdated drivers. ### Fast checks (do these first) - **Wi-Fi is ON; Airplane mode is OFF.** - **Stand close** to the receiver (same room). Miracast discovery is over-the-air Wi-Fi Direct. - The TV/projector shows the **ScreenBeam home screen** (receiver is ready). --- ### Verify the PC supports Miracast & 5 GHz - **Miracast status:** Press **Win + R →** `dxdiag` → **Enter** → **Save All Information…** → open the file → **Miracast = Available** (or *Available, with HDCP*). - **5 GHz radio present:** Open **Command Prompt**, run:  netsh wlan show drivers In **Radio types supported**, you should see **802.11a / ac / ax** (indicates 5 GHz capability). --- ### **Update Wi-Fi drivers** - **Device Manager → Network adapters →** right-click your Wi-Fi adapter → **Update driver**. - If no update is found, download the latest **Windows 10/11** driver from your PC/adapter manufacturer and reboot. --- ### **Nudge the adapter for Miracast** - **Prefer 5 GHz (if available):** Device Manager → your Wi-Fi adapter → **Properties → Advanced** → set **Preferred Band = 5 GHz**. - **Quick test for older radios:** Temporarily **disconnect** from your regular Wi-Fi, then press **Win + K** again. (Helps if the adapter can’t do Different Channel Mode.) --- ### Reduce interference - Move the PC and receiver closer; avoid metal enclosures behind displays. - Keep distance from dense AP clusters and other 5 GHz emitters. - If you manage Wi-Fi, avoid putting nearby APs on the **same channel** as the receiver’s P2P channel. ### Try again, or reset as a last resort - Press **Win + K**, select the receiver, enter the PIN if shown. - **Last resort:** *Settings → Network & Internet → Status → Network reset* (you’ll rejoin Wi-Fi afterward). --- ### Recommended Wi-Fi adapters (for reliable Miracast) - **Preferred (Wi-Fi 6/6E):** **Intel® AX-series** — e.g., **AX200 / AX201 / AX210 / AX211** or newer. - **Minimum (Wi-Fi 5):** **Intel® Dual Band Wireless-AC** — e.g., **8265 / 9260** (must support 5 GHz + Miracast). - Use the **OEM Intel driver** for Windows 10/11 whenever possible.
