hi firenice03,

sorry for my delay , i had problem with my home connection,
Do you think these information are enough go get mi WIFI get ready ...

thank a lot

[firenice03]

Couple of things might be worth a try..


1st may a restore point with TimeShift - should something go south you'll have a fall back.. Then another after you find resolution.
The following shouldn't bother the system but never hurts..


Try disabling Bluetooth - sometime BT has been known to cause WiFi issues. Verify..


Since it worked in LL3.8, may be kernel related - LL3.8 ships with Kernel: 4.4.0-112 whereas LL4.0 ships with Kernel: 4.15.0-22
You can use Lite Tweaks - Kernel Installer;  choose 4.4 at least to start with..

• Click the radio button next to the version, click install then reboot
  
• At GRUB make sure you select the 4.4 version, verify if WiFi is working
  
• Can use Lite Tweaks > Kernel Removal to remove 4.15 or any other kernels not logged into
  

The above are easily remedied to go back to the original system. Reboot select kernel 4.15 from GRUB, use kernel remover from Lite Tweaks to remove 4.4 (Cannot be logged into the kernel you wish to remove)


The following I wouldn't attempt without having a restore - it'll be easier to restore versus removing..
Depending on WiFi encryption: https://ubuntuforums.org/showthread.php?t=2347479

Hi firenice03,

I tried the "lite Tweaks - Kernel Installer" but  it doesn't take place , that is, I get an error saying " Your computer is not connected to the internet".

so it si impossibile to try the things you suggested. So it appear we are at the starting  point.

thanks for the help and your time!
Do you have any other suggestion ??

[firenice03]

Can you connect to the internet by other means? Ethernet cable?

Having access to the internet will also allow drivers/system update..
Menu > type Software > from Software and Updates > there is an "Additional Drivers" tab or from Menu > type "Install Drivers"

Hi Joss

I’m no expert on these things, and what I’m about to suggest might seem a little simplistic and obvious, but you could start with the basics to try to eliminate any install errors that may have occurred and could be causing the problem.

To start with, did you download the ISO correctly and verify the MD5sum and the media for integrity before installing?

Next, if you have a mind to re-install your system, run LL 4.0 live and connect to your network before clicking to install your system? If your wifi isn’t recognized in the live system, you could try connecting to your router via an Ethernet cable anyway and then click to install.

The logic of the above is that as your system installs it will detect your hardware, including your Atheros AR9287 chipset, and then upon re-booting your newly installed system may connect to your wifi correctly as a result.

Apologies if you’ve tried all of the above, and for stating the obvious.

Good Luck!

Mart

Hi firenice03,

At this point , I think would be better to wait for a kernel update. if one will be available in a resonable time.
I lost a lot of time because of this.
sooner or later it had to happen. I give it up.

thank for your time and suggestions...

A kernel update nor a newer kernel (same process to add) may not alleviate the issue, if the driver was removed it may not be put back in..

If you have the Atheros AR3012 (shipped in some lenovo laptops like the z50 that i have) and linux lite 4.0 or ubuntu 18.04, you might have a problem with the adapter, and if you use the command dmesg you are going to get this error:
[sup]bluetooth: hci0: don't support firmware rome 0x31010000[/sup]

I found this solution that solve that issue...

1. Add the ukuu repo to your system:
[sup]sudo add-apt-repository ppa:teejee2008/ppa && sudo apt update[/sup]

2. Install ukuu:
[sup]sudo apt install ukuu[/sup]

3. Install the kernel 4.16.9 with ukuu:
[sup]sudo ukuu --install v4.16.9 [/sup]

4. And finally reboot

The problem with the AR3012 is caused by the kernel 4.15.0 shipped with Ubuntu 18.04 and linux lite 4.0 and the unique kernel i found  that solve that issue is the 4.16.9

pd: i'm not an english speaker so maybe the instrutions or the grammar is bad, sorry for that

Posted elsewhere. Might this help here also?
