Issue with Wifi on New Install

Postby MichaelBlucher » 2018-04-09 02:15

Hi

I've just downloaded and installed Debian (latest version) and found that the Wifi setup does not work.

I believe that this is a known problem.

Can someone please point me in the direction of a fix?

Please take into account that my Wifi connection does not work.
This email is being sent from my work and is many miles from the computer with the problem.

Regards
Michael B.

Hi

The reply that came back was:
02:00.0 Network Controller [0280]: Intel Centrino Advanced-N 6205 [Taylor Peak] [8086:0082] (rev 34)

I believe the correct driver to use is: iwlwifi

Assuming this is correct, how do I put the driver in place?

Regards

Connect TEMPORARILY by cable.

Issue the command to become Root:
Code: Select all
su

Issue the command :
Code: Select all
apt install firmware-iwlwifi

When it has finished remove the cable and reboot.

Is there a method that does not require an internet connection?

The wifi on the laptop is not working and I don't have a cable connection.

Download the firmware to your work pc then transfer to usb thumb drive. Bring the drive home and transfer the file to you home dir.
Open a terminal, su to root and issue the following command.
Code: Select all
dpkg -i irmware-iwlwifi_20161130-3_all.deb

Okay I've managed to get the iwlwifi drivers and they are now installed.
Note: It appeared they were already installed to start with.

I still have the same problem. No wifi networks are being found.

What do I try next?

Have you rebooted to let the firmware work?

Yes, I have rebooted

Is there a way to force the use of the driver?

I'm beginning to think its the network manager. The random mac address is not something I've seen on other systems.

P.S I'm currently booting between Debian and a Knoppix USB. So to use the web, I boot Knoppix. To apply the patch I boot Debian. Lots of re-booting.

It's okay the driver will be automatically loaded for the device, the firmware too if installed correctly. You can confirm the firmware load with
# dmesg | grep firm
and look for errors.

There's some info on NM here.
https://wiki.debian.org/WiFi/HowToUse
The most important thing is probably making sure you haven't tried ifupdown configuration at the same time, listing the same device in interfaces file conflicts with network-manager default setup.

You can use nmcli to get some info, there are a lot of options, probably start with
$ nmcli status
but read the man page, I don;t have it available right now.

The random mac feature usually doesn't prevent scan results, but I guess it's possible.

Another option to try: download the ISO that includes the non-free firmware and give it a shot. I don't think you'll need to go into a full install to see if the drivers are installed on that ISO, if it configs the network on setup, you would be good to go.

You can find the non-free firmware stable ISO here:
https://cdimage.debian.org/cdimage/unof ... 0+nonfree/

Yeah, 220, 221. Whatever it takes.

Hi

I'll try that (dmesg | grep firm) later when I get home from work.

The Knoppix USB I've setup to sort this issue out is using the same driver (iwlwifi). Works fine. Knoppix uses Gnome.

Under Debian (stretch) the scan does not find any wifi points at all. The detection should pick up around 10. This Debian is using KDE.

The main difference I see between the two systems is in the Network Manager.

Under Knoppix, it has a field for "device" which is set to my wifi cards mac address.
Under Debian Stretch, it has a Random mac address button. Even if I key my wifi cards mac address in manually it still fails to detect any wifi points.

Is it possible that the "Random mac address" function is a problem for some wifi cards?
