Wifi suddenly stopped working on Pop OS

I'm using Pop Os since a couple of months with a wifi PCI card and two weeks ago, the wifi stopped working. It disapeared from the system settings. I've tried a lot of things since then but nothing could revive my wifi. When I run rfkill nothing is returned. Also, if I run lspci | grep Network I have this result 05:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter (rev 03) I also followed this : https://forums.linuxmint.com/viewtopic.php?t=383673 , but when I run sudo modprobe -rv bcma wl I get this answer : modprobe: FATAL: Module wl not found. Now I'm a bit stuck and I don't know what to do. If anybody has an idea on how I can get my wifi back, it would be great !
