Wifi not connected

[unisus21]

I have acer aspire 4715z on newly fresh installed p6..but I cannot connect to my wifi..my card is Broadcom BCM4312 802.11b/g LP-PHY..can someone help me?

Can you open a terminal and post the output from:

Code: [Select]

lspci -vnn | grep -i netplease.


There's a very good chance that connecting your PC to your router via an ethernet cable, then running:

Code: [Select]

sudo apt-get install b43-fwcutter firmware-b43-installerwill sort out wireless.

I cannot post the output because I'm at work right now but I already done sudo update upgrade and installed b43 yesterday..getting some error..sudo modprobe also not executed..should I do sudo update again or reinstall p6..

Dunno yet .. you'll have to post the exact modprobe error .. and the output from the 'lspci' command above

[unisus21]

sorry what I mean is I already done sudo modprobe but terminal cannot execute that command..so no input on that..but ill get to you when I'm done lspci command above

No command 'lscpi' found, did you mean:
 Command 'lscpu' from package 'util-linux' (main)
 Command 'lspci' from package 'pciutils' (main)
 Command 'lscp' from package 'nilfs-tools' (universe)
lscpi: command not found

Hi unisus21, how's it going?  Before you install anything else, complete your upgrade process.  With the ethernet cable attached, run the following command in a terminal window:

Code: [Select]

apt dist-upgradeWhen the dist-upgrade has completed, it's very important you reboot your computer.  When the reboot has finished, unplug your ethernet cable.  Has your WiFi now sprung into life  ?

For future reference, could you please remember to encapsulate terminal outputs with the Insert, Code # function.  For extra long outputs, please use the Spoiler, Sp function.  It preserves the original format of the output.  This makes it easier for future visitors to relate to their own issues.  These functions are found in the forum editor, above the,  Embarrassed and  the Cry emoticon respectively.  I've done this for you this time - many thanks  .
