No Wifi Dell Inspiron 1545 (Solved)
« on: July 02, 2014, 12:55:21 pm »
Dell Inspiron 1545 laptop with Windows 7 installed & Peppermint 5 on usb stick.

From this forum & Google learned for linux wifi I needed Broadcast STA driver.  Unsuccessful installing via apt-get (because Broadcom retains proprietary rights?) but successful via Software & Updates/Additional drivers.  Temporarily had wifi but lost it on reboot.

Additional drivers shows CHECKED "Broadcom Corporation Wireless 1397 WLAN Mini-card" & "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)."  However, after reboot it shows CHECKED "Do not use the device," even tho each time I check "Continue using a manually installed driver."

Any suggestions how an old non-techie can rectify this indignity?

(Currently have Peppermint 5 as sole OS on Dell Inspiron Netbook, arriving via 3 & 4.)

Try this...

With your PC connected to your router with an ethernet cable...

Open a terminal and run these commands in sequence:
Code: [Select]
sudo purge bcmwl-kernel-source
(don't worry if that command fails .. just carry on below)
then
Code: [Select]
sudo apt update
then
Code: [Select]
sudo apt upgrade
then
Code: [Select]
sudo modprobe -r b43
then
Code: [Select]
sudo apt reinstall firmware-b43-installer linux-firmware-nonfree
then
Code: [Select]
sudo modprobe b43
now post the output from:
Code: [Select]
sudo iwlist scanning

The good news: the un/reinstall went smoothly & at the end I again had a wireless connection.

The bad news:  it didn't hold.  After rebooting, no wifi & the only network options offered are VPN Connections.
There was one difference:  under Additional Drivers "Using Non-free firmware for Linux Kernel drivers from
linux-nonfree (proprietary)" remained checked; "Do not use the device" remained unchecked.

Well, let me add that I really appreciate not only your help but the speed with which you responded; you guy are great.
If you come up with any other ideas, please let me know; I've been working with this for a while now & hate to give up.
Again many thanks.

does it come back to life if you run:
Code: [Select]
sudo modprobe -r b43
then
Code: [Select]
sudo modprobe b43

Wow.  Yes, in fact I am replying from the Dell laptop itself.  I was about to close the terminal & go to another computer to
reply when the connect prompt appeared.  Haven't rebooted yet but will give it a try after closing.

Again thanks; and more thanks for keeping at it.

Reboot, no wifi at restart, but on again after the two modprobe commands.  So at least now I have a working solution.  Embarassed to say that I have no idea what this implies, but suspect that you do.  At any rate you've made my morning.  Hope to hear from you again.  Many thanks; gee, you guys really are great.

can you REBOOT, then without running the above commands (so wifi is still not working) run:
Code: [Select]
lsmod
then copy the output to a text file.

now run the 2 commands to get wireless back .. then post that output back here.

OK, doesn't look like the b43 driver module is getting loaded at bootup, so let's add it to the "modules" file which should tell the system to load it.

Open a terminal and run:
Code: [Select]
sudo gedit /etc/modules
when the file opens, add a single new line at the bottom that reads:-

b43

SAVE the file and exit gedit.

Reboot to test.

Works like a charm; I've rebooted several times, shut down & restarted:  it works like it should.

I haven't done much posting in forums. I usually just lurk in them & learn. But I have posted where I got no response at all.  I have never before posted where I got such fast and such expert help as I have received from you. You come well labelled, if karma represents good feelings and good work, and veteran skill gained from experience. I'm not a Linux veteran, obviously, but as a navy veteran I could send you the signal Bravo Zulu.  How about just a simple thanks for a job well done.  It was a pleasure to watch you work.

I'll hold off to late afternoon or early evening in case you wanted to do anything else; then mark the post solve.
