Hello,
on an Apple MacBook Pro running debian testing (kernel package is
version 5.9.1-1), I have this card:
# lspci | fgrep Netw
02:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)
The card is recognized and managed by the broadcom-sta driver but it
does not displays the list of available networks:
# iw wlp2s0 info
Interface wlp2s0
ifindex 3
wdev 0x1
addr d8:a2:5e:94:71:2f
type managed
wiphy 0
txpower 200.00 dBm
# iw wlp2s0 scan
# iwlist wlp2s0 scanning
wlp2s0 No scan results
some errors are collected by dmesg:
