linux newbie problem:
/i've installed 14.04 on an acer aspire laptop and cannot get the wifi to work (no wifi symbol in taskbar even).
I've tried following the instructions here: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
lspci -vvnn | grep -A 9 Network 0a:05.0 Network controller : Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02) Subsystem: AMBIT Microsystem Corp. TravelMate 2410 [1468:0312] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 32 Interrupt: pin A routed to IRQ 20 Region 0: Memory at d0004000 (32-bit, non-prefetchable) [size=8K] Kernel driver in use: wl 0a:06.0 CardBus bridge : Texas Instruments PCIxx12 Cardbus Controller [104c:8039]
not sure that's pasted in right so I summarise: broadcom BCM4318 picid:[14e4:4318] kernel driver in use:wl
So I tried following the instructions down the page to install the B43 using the open-source firmware-B43-installer, and restarted, but that didn't solve the problem.
so I tried the next bit:
2.04 (Precise Pangolin) - 14.04 (Trusty Tahr) Open a Terminal and if you haven't already done so, update your package list:
sudo apt-get update
If you have a b43 card use the command
sudo apt-get install firmware-b43-installer
and restarted, again with no improvement, so to the next bit:
Switching between drivers
If you card is supported by more than one driver then use the modprobe command to test the drivers. First unload all conflicting drivers (this includes removing the driver you're trying to install):
sudo modprobe -r b43 bcma
sudo modprobe -r brcmsmac bcma
sudo modprobe -r wl
To load a specific driver use one of the following commands:
sudo modprobe b43
sudo modprobe brcmsmac
sudo modprobe wl
Allow several seconds for the network manager to scan for available networks before attempting a connection.
this is where I got stuck - the 1st two sudo modprobe -r commands were fine but when I try and remove the wl driver I get:
modprobe: FATAL: Module wl is in use.
I cannot see how to proceed from here so I would appreciate some direction.
rfkill list 0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no sudo iwconfig [sudo] password for a: lo no wireless extensions. eth0 no wireless extensions.
not sure what other info I need to supply (complete linux newbie sorry). ethernet (wired) internet is working OK. Thx
