That looks strange but I don't use NetworkManager so I don't know what's normal for that.

Yes, it's strange, but apparently due to NetworkManager, per packetlife.net/blog/2008/sep/24/169-254-0-0-addresses-explained.

I would disable NM completely and try connecting manually to narrow down the source of the problem.

I spent most of the afternoon figuring out how to disable NM and configure /etc/network/interfaces using https://wiki.debian.org/NetworkConfigur ... _Interface and https://wiki.debian.org/WiFi/HowToUse. So now I have the below and it does bring up ethernet, but wireless is still not working. In addition, reboot stalls with the message "A start job is running for Raise network interfaces." for a bit more than 6 minutes, though it finally reboots. My revised interfaces file:

Code: Select all

cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# my ethernet

auto eth0

allow-hotplug eth0

iface eth0 inet dhcp

iface eth0 inet6 dhcp

# my wifi device 

allow-hotplug wlp12s0.

iface wlp12s0. inet dhcp

Chrisdb:

It could be an issue with the driver.
Something else you can try as root:

Code: Select all
apt-get purge broadcom-sta-dkms
apt install firmware-b43-installer


Now reboot and try again.

Purge works fine, but

Chrisdb:

The link for firmware-b43-installer_019-4_all.deb came from following the directories at https://packages.debian.org/jessie/all/ ... r/download

[Winston]

Chrisdb - Update

Found some more links to put in /etc/apt/sources.link, and sudo apt install firmware-b43-installer worked.

BUT now reboot stalls on a line "A stop job is running for Raise network interfaces" for a bit more than 6 minutes before reboot completes.

Now on ping 8.8.8.8 without the ethernet connection, I get

Code: Select all

From 192.168.1.14 icmp seq=10 Destination Host Unreachable

which means the default gateway is misconfigured
The hostname command gives 2 different answers, but resolv.conf is still correct

Code: Select all

mike@Debian:~$ cat /etc/resolv.conf
nameserver 192.168.1.1

192.168.1.14 is the address of the laptop itself.

arp now has 3 addresses, the gateway and two of my network printers with fixed addresses

So I'm thinking I should re-install broadcom-sta-dkms and reset things as they were before it was removed. Do you agree?

[Chrisdb]

sudo apt install firmware-b43-installer_019-4_all.deb

This is not the way to install packages on Debian
see: https://wiki.debian.org/DebianPackageManagement

you're missing the non-free repo in your sources. Take a look at the second example from the following link:
https://wiki.debian.org/SourcesList#Exa ... urces.list
To add backports, use the third example

BUT now reboot stalls on a line "A stop job is running for Raise network interfaces"

Did you deactivate NetworkManager?

Code: Select all

systemctl disable NetworkManager

Also, what does your final 'interface' file look like?

Did you configure wpa_supplicant?
https://wiki.debian.org/WiFi/HowToUse#wpa_supplicant

[Head_on_a_Stick]

Code: Select all

allow-hotplug wlp12s0.

iface wlp12s0. inet dhcp

     wireless-essid Corniche5

     wireless-mode Master

Why have you followed the "wi-fi hotspot" instructions?

Try https://wiki.debian.org/WiFi/HowToUse#W ... d_WPA2-PSK instead, the first bit should provide some diagnostic information if it doesn't work.

EDIT: and there shouldn't be a full-stop after the interface name, not sure why you've added that. It certainly doesn't appear in the guide.

[Chrisdb]

After installing the new driver, your interface was renamed to 'wlan0'.

You should change your configs accordingly

Also for wpa_supplicant you should not have to define a service yourself.
Take a look at the link HoaS provided. You probably use WPA-PSK...

[Head_on_a_Stick]

Did you configure wpa_supplicant?
https://wiki.debian.org/WiFi/HowToUse#wpa_supplicant

Yes, created (it didn't exist) and configured as below and rebooted

There is already /lib/systemd/system/wpa_supplicant.service (and several others) so delete your file and disable it.

This thread is getting really silly now so let's start from scratch and I'll spoon-feed you commands to try. You obviously can't follow the linked guides for whatever reason.

So first please provide a list of enabled services:

Code: Select all

systemctl list-unit-files --state=enabled

And we'll take it from there.

Please don't try anything else unless we specifically tell you to or this will just go on forever.

Okay so let's stop networking.service (which runs ifupdown and is controlled via /etc/network/interfaces):

Code: Select all

# systemctl stop networking

Then create a configuration file for wpa_supplicant:

Code: Select all

# wpa_passphrase 'ssid' 'password' > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

^ Replace ssid with the name of your access point and replace password with the actual password.

Now try associating with the access point:

Code: Select all

# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

And then assign some addresses:

Code: Select all

# dhclient wlan0

You should now be connected via wireless. If any steps fail then please post the error messages in full (along with the command that preceded them).

[Winston]

My laptop can't find this command

Code: Select all

root@Debian:/home/mike# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
bash: wpa_supplicant: command not found

Also, my wireless name has been wlp12s0 and not wlan0. Currently it's not running

Code: Select all

/sbin/iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

[Chrisdb]

First install 'wpa_supplicant':

Code: Select all

# apt install wpasupplicant

Next what is the name of your wireless interface now:

Code: Select all

ip addr

So what happened to your wireless interface? You had a wlan0 last time we checked and a wlp12s0 earlier on in the thread. Your wireless card no longer has the wl driver, did you remove that or something?

I'm getting bored of this thread tbh, Broadcom is always a bastard under GNU/Linux.

I'm getting bored of this thread tbh, Broadcom is always a bastard under GNU/Linux.

I told him to remove the broadcom-sta driver since it (wl) blacklisted his ethernet 'b44'. Either he would have to use his ethernet or wifi, but both would be a problem. According to the wiki his BCM4321 also is covered by the "firmware-b43-installer" package. And indeed this listed the 'wlan0' interface earlier. But for some reason now he's got no wireless interface anymore...
