I have a laptop with a Broadcom Wireless Adapter (BCM43455) that I would like to dual-boot with Ubuntu and Windows, however, whilst it have no problems with Windows, regardless of whether I run a liveCD or install it Ubuntu refuses to recognise my Wifi Adapter.
I have tried lspci -vnn
, lshw
and lsusb
(just to be safe), all as root, but none of them show anything even network related.
Ubuntu doesn't show any additional (proprietary) drivers that it could install either, and while there is a question about Broadcom Adapters not working in general here, all of the answers assume that you can see the device listed in lshw
and lspci
but just can't use it.
What can I do about this?
EDIT: Here is the output of dmesg | grep -i sdio
, as requested:
