Title:
  After suspending and turing the PC back on, the wifi disappears
  possibly because of D3cold state !

Status in linux-oem-6.14 package in Ubuntu:
  New

Bug description:
  I have recently purchased this lenovo yoga 7 laptop and dualbooted it.
  When I boot into ubuntu, the wifi works fine, but then when I hit
  suspend and try to log back in the wifi just doesn't work.. It can't
  connect to the available network. As of now with trying a few fixes it
  doesn't even show up anymore. The problem is likely due to the D3Cold
  state and that the firmware is not able to handle the power states. I
  used gemini and Chatgpt to fix this but their methods are just not
  working. I need help !!

  After resuming from suspend, the Wi-Fi option disappears entirely. The
  hardware becomes inaccessible, and dmesg logs show errors like iwlwifi
  0000:01:00.0: Unable to change power state from D3cold to D0, device
  inaccessible and HW_REV=0xFFFFFFFF, PCI issues?. This happens on a
  Lenovo (83KF) with an Intel BE200 card. The only way to restore Wi-Fi
  is a complete, cold shutdown (not a simple reboot)
