Intel BE200 Wi-Fi Resume Fix on Ubuntu 25.10

Intel BE200 Wi-Fi Resume Fix on Ubuntu 25.10

This guide documents the suspend/resume Wi-Fi failure observed on a Lenovo IdeaPad running Ubuntu 25.10 desktop and walks through the exact remediation steps that were validated on October 27, 2025. Use it after a fresh OS install or kernel update if the problem reappears.

1. Problem Overview

  • Hardware: Lenovo IdeaPad Pro 5-14IAH10 with Intel BE200 (Wi-Fi 7) controller at PCI address 0000:01:00.0 (device id 8086:272b).
  • Kernel Symptom: After resuming from suspend (s2idle), the wireless adapter stays in PCI power state D3cold and never returns, leaving wlp1s0f0 unavailable. Logs show:
    • Unable to change power state from D3cold to D0, device inaccessible
  • timeout waiting for FW reset ACK followed by repeated firmware crashes.
