Tag: Wifi

On March 16, 2019 I ran the software update checker and told it to install all updates. (Up-to-date as of the previous week if not later.)

One update, for wifi, failed. I did not log its name because I assumed Ubuntu would roll back the changes. Wrong. On reboot WiFi wasn’t working.

The laptop has an Ethernet port so it is running online. Running the software update returns with no updates needed.

I’ve gone online and found many Ubuntu wifi trouble shooting guides but each one I’ve tried has run into problems after the first few steps.

The PCI WiFi is Intel Corporation Wireless 8265 / 8275 (rev 78). On the Intel site they have iwlwifi-8265-ucode-22.361476.0.tgz but its for kernel 4.6 not 4.4. (uname -r returns “Kernel: 4.4.0-143-generic”) Its latest update was March 5th which probably lead to the problem on the 16th.

Under Software & Updates Additional drivers Intel Corporation: Unknown This device is using an alternative driver (selected) using oem-wifi-intel-iwlwifi-lp1757035-4.4-dkms driver in DKMS format wrapped by dkms-helper, from oem-wifi-intel-iwlwifi-lp1757035-4.4-dkms-dkms (open source) Only other option is “Do not use”

I selected “Do not use” and the first time it took 5 minutes, the second over 20 minutes and wasn’t finished so I rebooted and it was selected. Selecting the oem driver took maybe 2 seconds but didn’t fix the problem.

lshw -C network shows the wireless and ethernet adapters wireless is recognized properly as Intel

lspci -v wireless is listed at intel 8265 / 8275 rev 78

lshw – C netowrk wireless configuration line only has latency=0 (no mention of driver)

I couldn’t tell if the correct module was loaded or not but nothing looked like a WiFi module to me.

I do have a full user data backup and the original factory image so I can restore the image if necessary but will lose all the programs installed except Ubuntu and all the tweaks to the interface.

From what I’ve read Ubuntu will detect the hardware and install the appropriate software except maybe not with these Dell / Intel / Ubuntu drivers. Except there was an updated driver coming though the software update channel.

I don’t know where to go form here. Can I get the driver through Ubuntu or do I have to restore the factory image?

I did submit a report about the error using the error reporting tool but couldn’t find a local copy. It it stored somewhere local?

Thank you for your help,

Luke
