Hello. I just noticed something. My router cannot identify the hostnames of devices connected to the 2.4 GHz band. I discovered this while testing with my phone (I usually connect to the 5 GHz band), and I noticed the issue when I switched to the 2.4 GHz band. I had previously noticed the same issue with my mom's phone, but I assumed it was because it's an older device. Additionally, the MAC addresses appear differently on each band. What do you think might be causing this, and what are the potential solutions?
