intel network controller

Postby vilbjorg » 2017-12-15 16:14

Hello
I have difficulties getting wifi to work on a fresh install of Jessie, xfce (need Jessie for a graphics environment which unfortunately is not updated for Stretch) Neither Wicd nor Connman can see any networks. I have a dual install on the computer, the other system is AVLinux Stretch, here wifi works fine.

any hints very welcome, thank you in advance

connmanctl> scan wifi

Is firmware-iwlwifi installed?

yes I installed firmware-iwlwifi, that it why I am not sure what to do next, the printout from 'lspci -v' shows that that the driver is there (as far as I understand)

What's the state of the RF killswitch (rfkill list)?

after
'rfkill unblock all'
then Connmanctl can see the networks. (Wicd still cannot see any networks) At this point I did not manage to connect to a network , I get some error from Connmanctl, but perhaps that is a matter of me reading the manual tomorrow.
Still could it be that there is some permission setting some where which prevents Wicd to see networks? .. will try to look at that. I have to run Connmanctl as root

In Wicd, did you enter the adapter name? eg wlan0 , wls1 and so on.

I really doubt that the 3.16 kernel has driver support for that recent hardware. A minimal websearch should confirm or deny this. The solution is to install and use the newer kernel and firmware from jessie-backports.

What desktop is forcing you to use Jessie, by the way?
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: GIMP 2.10.2, Pale Moon 27.9.3, wine-staging 3.10, QuiteRSS 0.18.11, Linux kernel 4.17, Krita 4.0.4

3.16 supports
Code: Select all
PCI: 8086:088E Intel Corporation Centrino Advanced-N 6235
PCI: 8086:088F Intel Corporation Centrino Advanced-N 6235

What is the output of
Code: Select all
lspci -nn | grep -i network

Hi , thanks a lot for all the replies, I managed to connect using connmanctl, which is fine enough for now. - The hardware is not that new, had both Wheezy and Jessie running with wifi before on this computer, so it must be some settings on this fresh install.... The reason for me at the moment to make this dual install of Jessie is to make some video work in a wrapper for OpenGL called 'OpenFrameWorks', they did not update this for Stretch, I believe the main problem is the version of POCO which they use.
