Title is self explanatory. For background, I am currently running Asahi Linux on my M1 MBP. Whenever I connected the hotspot without data being turned on, it somehow still worked like any regular wifi. I even ran several updates in the system and downloaded multiple apps in this wifi, which I find it amusing. But out of curiosity, I wanted to know from you guys that what could the reason be for this.
EDIT: So after following the advice of jet@hackertalks.com, I relized that the hotspot is using the network of my University’s Wi-Fi, which explains why the hotspot worked even with the data turned off.
It’s interesting on it’s own, since I do remember my android phone disconnecting from wifi when enabling the hotspot. If I understand it right, this type of wifi bridge requires two radios to work efficiently, but it may have changed in latest Wi-Fi standards. Curious nontheless.
I’m guessing it uses the 2.4ghz antenna to transmit and the 5ghz antenna to receive or vice-versa
Exactly, hence this post.
