Public bug reported:
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)
