Hi everyone, I installed Zorin os 17 Core on two DELLs Latitude E6230 recently. I am having issues with WIFI. Every time I restart the computer, WIFI is not coming up at all. On the other hand, if I shutdown the computer & reboot, WIFI is working fine. Would it be possible that a 'restart' disables WIFI and the boot process (when you restart only) is not recognized at all ?
I am not having this issue on other computers running 17 ... like Lenovo's laptops and other DELLs.
First thing: On Zorin OS be sure to launch terminal and run
sudo apt update && sudo apt upgrade
This likely is a BIOS setting that needs to be adjusted.
The easy way to address this is to restore all BIOS settings to default. The more nuanced way is to examine all settings and identify the culprit.
Usually it would be a PCI enumeration value since Wifi cards often occupy a PCI slot.
One thing to double check though, both if you restore to defaults or if you Identify and change a setting is whether Secure Boot is enabled or disabled. Secure Boot is generally for Windows OS use and can interfere with GnuLinux applications and drivers.
If that is no good; then you would want to check your kernel version:
uname -r
and may need to test a different kernel. You can try an earlier one from Grub Menu > Advanced Options for Zorin.
For a later kernel, you can install a TuxInvader patched Mainline. Which depends on whether you are using Zorin OS 16 or Zorin OS 17. Also, please state if youare dual booting Windows OS.
Here are 2 printscreens I just generated.
The first one is when I clicked the RESTART button, the second one is when I power OFF the computer and turned it back on. You see the WIFI icon on the 2nd printscreen not on the 1st one ...
Both machines are having this issue. One has dual-boot WIN10 & Zorin, the other one Zorin only. Both computers work fine (WIFI is available) as long as I power them OFF and ON again. The 'RESTART' button if pressed seems to disable WIFI ???
Hi ... Suggested links did not help. All the proper drivers and configurations files are fine and up-to-date. Still, for whatever reason ... if I issue a shutdown -r from a terminal session (equivalent of RESTART button) the WIFI is not coming up. If I issue a shutdown -P (equivalent of POWER OFF button) and bring the computer back ... the WIFI is working like a charm ...
Hi everyone,
this is to let you know I found why I had those weird issues with my WI-FI. For now i'm only connecting to 2.4GHz networks. Not saying 5GHz networks don't work but if I am connected to 5GHz network and if I do a 'sudo reboot' or click the 'restart' button, WI-FI will not be coming up. WI-FI reconnects properly if I do a 'sudo shutdown' or click the 'Power OFF' button (no matter if I am connected to a 2.4 or 5GHz network).
Before finding this ... I used the last 3 available versions of the DELL BIOS and it did not fix anything. Also made sure I had the proper drivers. Tried to boot to different kernels (no luck) ... I have an IPTV app running and 4 computers (Windows 10 and/or/both Zorin) running properly with a 5GHZ default connection. For some reason, these DELL Latitude E6230 have WI-FI issues connecting/re-connecting to a 5GHz network (only when rebooting them).
i'll be digging a bit more on this, but so far it's working ...
freq[uency]/channel
Give the list of available frequencies in the device and the number of
defined channels. Please note that usually the driver returns the
total number of channels and only the frequencies available in the
present locale...
My router was configured to channel 149. I changed the channel to one of the listed 5GHz channel as per iwlist and it resolved my issue.
That is some impressive troubleshooting. I'll bookmark this thread to know what to look for in case I run into strange behaviors in the future. Thanks for the update!
