Estabilidad Wi‑Fi y aislamiento de clientes

Symptom: devices never see each other even though both show full Wi-Fi bars.

1. Confirm both endpoints joined the same SSID and frequency band. Mixed 2.4 GHz and 5 GHz SSIDs sometimes split clients unexpectedly.
2. Disable guest network features that block device to device traffic.
3. Check for AP isolation, client isolation, or Wi-Fi hotspot modes that hide peers.
4. Temporarily connect both devices to a known clean test router to prove the software path.
5. Update Wi-Fi drivers on the Windows host; old drivers break Miracast style sessions silently.

Remoto entre redes distintas

Symptom: local mirroring works, remote path fails immediately.

1. Verify both sides can reach the public internet without a captive portal intercepting TLS.
2. Check upload bandwidth on the sending side. Remote mirroring is sensitive to uplink congestion.
3. Close VPN clients that force all traffic through tunnels incompatible with UDP requirements.
4. Retry after power cycling the modem when bufferbloat spikes are suspected.

Buenas prácticas de streaming

Symptom: mirrored gameplay or camera feeds tear or drop frames.

• Lower source resolution before raising bitrate caps.
• Prefer wired Ethernet on the receiving PC when possible.
• Close background sync tools that saturate disk IO.
• Rehearse audio routing: some apps block mirrored audio for DRM reasons.

1. Arrive early to join the institutional SSID and accept any terms portals.
2. Disable personal hotspot fallback that moves the phone off school Wi-Fi.
3. Set do not disturb to silence notifications that should not appear on screen.
4. Prepare a PDF fallback on USB in case multicast is blocked entirely.

Toques al controlar un PC desde el teléfono

Symptom: taps land offset from the visible cursor.

• Match display scaling settings between mirrored resolution and native panel resolution.
• Rotate the phone only after the session stabilizes; some stacks relayout aggressively.
• Use full screen receiver mode to remove window chrome from hit testing math.

Orden para ajustar la calidad

Start with network, then resolution, then codec or bitrate knobs, then hardware upgrades.

Buenas prácticas

• Document baseline metrics before changing three variables at once.
• Keep firmware on access points current for Wi-Fi 6 scheduling benefits.
• Use shorter distances between devices when interference is high.
