Hi,
Please find below the lspci log. Actually this old 32-bits laptop has an Ralink corp. RT3090 Wireless whose driver is complicated to find (forums post led to resource server that do not exist anymore), tried a process that seemed to work for people (https://ubuntuforums.org/showthread.php?t=2372045) but no Network Manager showed up (pasted as well below the result of the lspci -nnk | grep -A2 0280 command).
So I did another test plugging a WiFi Realtek USB device that works perfectly well (once followed this install process:
github.com/kelebek333/rtl8188fu) for the old 32-bits desktop PC on which I also installed Bodhi. But the Network Manager did not show up either.
