For some reason I could use the wifi connection just fine yesterday and now (next) day I can't seem to connect to any wireless point. I'm not sure but it's possible I did an update yesterday of the kernel which might have resulted in this.

I've tried to fix the problem following the method described in Wireless Network not showing with iwlwifi card since I got the same error:

Error! The /var/lib/dkms/backport-iwlwifi/8324/5.13.0-39-generic/x86_64/dkms.conf for module backport-iwlwifi includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch. This indicates that it should not be built. Skipped.

when trying to reinstall 'backport-iwlwifi-dkms', it seems this hasn't solved it. Although trying the remove command before I tried to install the version '9340-0ubuntu4' resulted in the error

sudo dkms remove backport-iwlwifi/8324 -k 5.13.0-39-generic resulted in the error Error! There are no instances of module: backport-iwlwifi 8324 located in the DKMS tree.

I tried the proposed solution anyway since I've got no idea what else to do but it didn't seem to have solved the problem. My kernel version is 5.13.0-39-generic. Some info:

lspci -v:

Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)
    Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak]
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at b4518000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

In the dmesg | grep iwl command iwl is red, in the lsmod |grep iwlwifi command iwlwifi is red also. Not sure what to do now, could it be hardware related?

Sorry if the layout isn't all that great, first time making a thread.

EDIT:

  • The items in RED are the search strings that you used. Just info. Your problem has occurred because of the new 5.13 kernel. Edit your question and show me dkms status and lspci -nnk | grep 0280 -A5. Then, via the GRUB menu, boot back to a 5.11 kernel and see if it starts to work again. Start comments to me with @heynnema or I'll miss them.

  • We'd also like to see: sudo dmesg | grep wlp Welcome to Ask Ubuntu.

  • @heynnema I've put the output under "EDIT:". I'll try/check the 5.11 kernel in a bit.

  • I'm not sure that you need the backport driver. Do modinfo iwlwifi | grep -i alias | grep 0034 and you should get one hit, and then sudo dkms remove backport-iwlwifi/9340 -k 5.13.0-39-generic, reboot, then redo the modinfo command, and confirm that you still get one hit. Also, it looks like you've tried to connect to three different access points, correct? Are they on the same router? Have you rebooted the router yet?

  • @heynnema Doing the modinfo command gave one hit, removing the backport , rebooting and redoing the command still gave one hit. The 3 different acces points are wifi provided by the residence where I'm at (student) so rebooting the router won't be possible for me.
