So, from the result of: # dmesg | grep firmware -> you know that kernel module "b43" is missing some firmware (ucode15.fw) After enabling contrib and non-free repository, you can search for related packages: $ apt search b43 This lists interesting packages: "firmware-b43-installer" and "firmware-b43legacy-installer". Next run: $ apt show firmware-b43-installer and $ apt show firmware-b43legacy-installer -> this show that these packages are useful for different chipsets, so you need to know which one is in you laptop. As pointed Henrique de Moraes, you can run "lspci" for that: … Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) … So, finally, if you see that this device is not working well, you can install "firmware-b43-installer" :-) Then reboot you computer to check that errors from dmesg have disappeared.
