I installed MacOS Sequoia 15.2 Beta 3 this morning. It worked fine till the afternoon but after that, I could no longer connect to the internet. I was able to join wifi networks and hotspots but it would just show no internet connection. Tried connecting via iPhone USB and LAN too but wasn't able to get it to work. Finally with no other option had to reinstall mac os. Gladly, the recovery tool installed the Beta 2. Learned my lesson, would never upgrade to developer beta ever again (at least not on my work laptop).
