Olá pessoal...A algum tempo venho enfrentando problemas com as placa de rede Broadcom, tanto para "b43" seja legacy ou não, assim como "wl".
Já subi todos os módulos que podem imaginar com e sem DKMS para ver se resolvia o problema numa maquina com o seguinte HARDWARE.
Arquitetura: x86_64
Modo(s) operacional da CPU: 32-bit, 64-bit
Ordem dos bytes: Little Endian
Address sizes: 39 bits physical, 48 bits virtual
CPU(s): 8
ID de fornecedor: GenuineIntel
Nome do modelo: Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz
Os Sistemas operacionais que testei e que em todos houve problemas foram:
Pop!_OS 21.10, Ubuntu 21.10, Debian 11, CentOS 7, 8 e recentemente o 9, Fedora, OpenSuse e etc.
Agora o sistema instalado é o Pop!_OS 21.10 e a saída para "lscpi" é:
