Read my post again, carefully this time.

And use code tags for terminal output or I'm out. The quote button will show you how I've edited your post to do that.

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

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

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.

Make sure you check the blacklist (b43 should not be blacklisted).

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

     wireless-essid Corniche5

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

192.168.1.14               
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?

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.

Re: No internet

#38 Post by 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...

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.
