I have a very old Dell Vostro 1015 laptop, and just installed Ubuntu 18.04.3 LTS on it. The problem is that I cannot use wifi, in the wifi settings it says "no wifi adapter found" (the bluetooth has the same issue). The internet works with ethernet cable though.
I did extensive research here in the forum but none of the solution options worked, I suppose each case is specific:) Therefore I run the wireless-info script command, please see the result in the linked Ubuntu Pastebin sitewireless-info
What I've done? I've tried to update the system, nothing; to restart the network manager, nothing; and to install the most up-to-date driver for my wifi adapter according to this r8168/r8169 RealTek driver module troubles nothing. Please, help me! thanks a lot!!!!
