My current test setup has 3 machines in the same wifi network * The laptop with the intel 8265 which has network problems * A phone * A desktop running wireshark in monitor mode If I try to ping the phone from the laptop, the machine in monitor mode sees frames going from my laptop to phone and back. This is the case both when my laptop is seeing the pongs and when it isn't. The wifi network is encrypted, so I can't be sure the frames have the pings and pongs, but the data length is always 100 bytes. When the ping program is not getting the pongs, neither wireshark or a small xdp program on the laptop will see them either, so they are being dropped at a lower level. Wireshark on the laptop still reports broadcasts (like ARP) and multicasts (like mDNS). I have had similar issues with both a 6.1.32-0-lts and 6.3.4-0-edge alpine kernels, so I suspect a firmware issue, which is: firmware-version: 36.ca7b901d.0 8265-36.ucode Following https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging I have enabled CONFIG_IWLWIFI_DEBUG and CONFIG_IWLWIFI_DEVICE_TRACING and installed trace-cmd, but I don't know what to check next. I have also reported this at https://bugzilla.kernel.org/show_bug.cgi?id=217535 Thanks, Rafael
