Network Manager Not Starting At Boot

Postby sudowhammy » Fri Oct 13, 2017 11:22 am

All,

I am noticing an issue with LM18.2 & network manager at boot where network manager does not always start after a user logs in. This issue happens on the base LM18.2 image and any update with network manager has not addressed it. I am thinking it is race condition at boot because the issue does not happen all the time.

In order to temporarily fix the issue, I have restarted the network manger service via sudo. A reboot of LM18.2 will sometimes also addresses the issue. However, it is not a permanent solution. I have also tried changing the power management setting on wifi without any success. The laptop in question is a new Dell XPS Developer Edition (9350). The laptop unfortunately is my parents laptop I got for them and is not my personal laptop. Consistently restarting network manager via sudo is not possible because they do not have sudo access.

Any thoughts on how to identify & resolve this?

Thanks!

Anyone have ideas? Re-installing the package also does not resolve the issue.

Yeah, I'm not a huge fan of that solution.

I would try disabling wifi power management as it can cause the wireless module to crash

Code: Select all

sudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

We should also check to see if the firmware is the latest

Code: Select all

sudo apt-get install linux-firmware

Reboot


Return to “Wireless”
