I found many similar questions and followed this one. As per the accepted answer, in case the status of wireless interface listed as *-network UNCLAIMED, I should follow the steps to install new drivers. On heading over here, under additional drivers section, I don't see any driver recommendation instead it shows this . Now how should I proceed? None of the answer in the last link solves this.

Machine is dual boot, but on windows side, wifi is working.

UPDATE: Lucky or Unlucky, can't decide. Maybe lucky if it is solved forever. And Today it happened again. Here are the result of sudo modprobe iwlwifi && sudo dmesg | grep iwl

WORKING: (recorded yesterday when it was working)

  • Let's have a look at the log. Please edit your question to add the result of the terminal command: sudo modprobe iwlwifi && sudo dmesg | grep iwl – chili555 May 26 '21 at 19:38
  • Today when I turned on the laptop, its wifi is working. I can connect to the wifi network and use it. This is not the first time I encountered this issue, it happens always. Yesterday when it wasn't working, I restarted the machine at least 10 times, and still, it reported the issue of not being able to find the wifi adapter. But today wifi is there. I'm worried I will be encountering this problem again. @chili555 Does the output log of the above command will help right now. I've to mitigate this issue forever. – y_159 May 27 '21 at 05:46
  • I don't know if the log readings taken when the wifi is working will show us any useful clues. I prefer those taken when it is not working. However, why not capture both? If the results are lengthy, post then here and give us the link: http://paste.ubuntu.com Please annotate each as WORKING and NOT WORKING. – chili555 May 27 '21 at 13:38
  • @chili555 added the results. – y_159 May 29 '21 at 14:42

    Is this a dual-boot with Windows? https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled – chili555 May 29 '21 at 15:00
  • yes, it is. I've already added this in question. – y_159 May 29 '21 at 15:03
  • Did you disable Fast Boot? – chili555 May 29 '21 at 15:43
  • @chili555 Yes, It's working now. Thanks. I don't know if it's gone forever or it will happen again . You write it as answer and take the credit. I've another ubuntu machine(dual boot) with same problem. but from last 6-7 months i've not been able to use the ubuntu OS on that bcoz of the wifi problem. ubuntu 19.10 or 19.04 is installed on that and I'm unable to run any update command on terminal to upgrade it to 20 LTS version. The only difference is as on this machine i was able to see wifi symbol on a few or several restarts but on that this was never the case. – y_159 May 29 '21 at 17:03

iwlwifi: probe of 0000:01:00.0 failed with error -110

Error -110 often suggests that, in a dual-boot system, Windows has not completely shut down the wireless device in order to allow it to boot quite quickly. Since Windows still has at least partial control of the wireless device, it is not fully available to Ubuntu. Please see: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

Please reboot into Windows and disable Fast Boot. Reboot into Ubuntu and I suspect that the Error -110 messages will be gone and that the wireless will now be working.
