 This page is a step by step guide to get Wi-Fi and Bluetooth working on T2 Macs. This guide is also applicable to **iMac19,1** and **iMac19,2**, which are T1 Intel Macs. This guide is NOT applicable for the rest of the T1 and older Intel Macs.
 
 !!! Bug "Unable to connect to Wi-Fi even after entering correct password"
-    Due to a [regression](https://lists.infradead.org/pipermail/hostap/2024-August/042893.html) since **wpa_supplicant 2.11**, Wi-Fi on broadcom chips is broken, thus affecting the T2 Macs as well. Please use [iwd](https://wiki.archlinux.org/title/NetworkManager#Using_iwd_as_the_Wi-Fi_backend) instead until the issue is resolved. Currently, only Arch Linux and EndeavourOS are affected.

Currently, only Arch Linux and EndeavourOS are affected.
 
 !!! Warning "Arch/EndeavourOS"
     If you're running Arch or EndeavourOS and have `apple-bcm-firmware` installed, you do not need to follow this guide further.
