I had this exact same experience with a brand new Dell XPS 15 I purchased around 2018 I believe. It came with a killer branded Wi-Fi card and I noticed shortly after purchasing that it would literally bring down my entire home network at the time. I don’t remember what router I was running or the rest of my home network set up at the time, but it was definitely a really bizarre thing to witness, I ended upreplacing the Wi-Fi card.
