* AI Disclaimer
AI was not used for any part of this post. LLMs are a powerful tool that are rapidly changing the tech landscape. While I recognize their value, they have created an imbalance. In the past, each article/post took more effort to produce than it took to read. Today, an LLM can generate an infinite pile of posts before lunch. While low quality and high quality posts are possible both with and without LLMs, I have written every word of this post and every line of code without an LLM. Therefore this article took more effort to produce than it takes to read.
# TODO: Add support to natter for a specific AI disclaimer tag that could be rendered below the article title

I could not get T-DLS working between two machines both running an MT7927. I had to replace =iwd= with =wpa_supplicant= since =iwd= does not support =T-DLS=. I managed to get the two devices to establish a link, but once that link was established, all traffic between those two devices immediately stopped.
