I’m trying to connect my MBP 14,1 A1708 (13" 2017, which uses a soldered Broadcom BCM4350) to my phone’s 5GHz hotspot. However, the phone’s SSID is not listed in the Wi-Fi menu.
After changing to 2.4GHz, the laptop can finally connect to phone’s hotspot but it is quite slow. Upon checking the kernel logs using sudo dmesg | grep brcm I found something interesting:

Using Fedora KDE 41, how can I solve the clm_blob and txcap_blob issue and get the Wi-Fi fully working?
