Hi all again, Update on my strange situation : immediately after installing Solus, I updated the system.
After rebooting as recommended, I did not have any network !
So, I decided to reinstall Solus from scratch.
The 2nd time was a redo of the 1st one.
Therefore, I gave up with Solus.
This is too bad because when I tried it, everything seemed promissing.
Therefore, unless somebody has the solution of this weird issue, I will not go further with Solus.
Disappointed !
Thank you for your kind assistance.
Cheers to the Community :.
