Wireless connection problem

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

Thanks for the quick response but I have installed these drivers as the page says to and my wireless is still not working.

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Thanks

dave@Godzilla:~$ sudo lshw -C network

Thanks again for the help.
The final command didn't give a readout.

ok and the output of:

dpkg -l | grep bcmwl

Thanks

dave@Godzilla:~$ dpkg -l | grep bcmwl
ii bcmwl-kernel-source 5.100.82.38+bdcom-0ubuntu4 Broadcom 802.11 Linux STA wireless driver source

Ok then run:

sudo modprobe -r b43-pci-bridge ssb wl; sleep 10; sudo modprobe wl

dave@Godzilla:~$ sudo modprobe -r b43-pci-bridge ssb wl
[sudo] password for dave:
WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
FATAL: Module b43_pci_bridge not found.
dave@Godzilla:~$ sleep 10
dave@Godzilla:~$ sudo modprobe wl

Not sure if this was what was supposed to be returned but after the sudo modprobe wl the network icon in the top right seemed to refresh but wireless still doesnt seem to be working.

then run:

sudo mv /etc/modprobe.d/blacklist /etc/modprobe.d/blacklist_dave.conf

Will clear up those warnings

OK so I ran sudo mv /etc/modprobe.d/blacklist /etc/modprobe.d/blacklist_dave.conf and then re-ran sudo modprobe -r b43-pci-bridge ssb wl; sleep 10; sudo modprobe wl

dave@Godzilla:~$ sudo mv /etc/modprobe.d/blacklist /etc/modprobe.d/blacklist_dave.conf

dave@Godzilla:~$ sleep 10
dave@Godzilla:~$ sudo modprobe wl

Sad to say that the wireless is still not working

Please copy-paste the following 3 commands into the Terminal.

sudo apt-get update

sudo apt-get remove bcmwl-kernel-source

sudo apt-get install firmware-b43-installer b43-fwcutter

Then REBOOT your PC and retest wireless.
