Hello, While in monitor mode, the 8265 will periodically transmit gratuitous LLC packets. In this mode, I would expect the wifi chipset to not transmit any packets at all (unless packet injection is being used). This behavior can be observed by a second wifi device in monitor mode. A display filter on wireshark/tshark of 'llc' makes these easy to spot. It seems these packets only get produced in presence of a few APs and/or STAs but I'm not sure of the exact cause. I don't see the LLC packets on very quiet channels. Other Details ------------- wifi chipset: Intel(R) Dual Band Wireless AC 8265, REV=0x230 kernel: 4.9.11 kernel backports driver: iwlwifi-stack-public:release/core33:6653:327571a8 I can use other backports versions if needed, but this was the version called out in: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release Firmware: 36.952d9faa.0 Thank you, Marco Fonseca
