be warned: I'm a complete newbie to everything Linux, so please ELIF and I'll try to keep up :)
I'm trying to set up Lubuntu on a cheapo laptop that currently has Windows 10. I have my live USB and successfully booted Lubuntu, but while checking to ensure that everything works, I see that I can't connect to wifi. My wifi adapter (Realtek RTL8723DE 802.11b/g/n PCIe Adapter) doesn't appear on Lubuntu's Additional Drivers page, and when I run
lshw -C network, this adapter is listed as "network UNCLAIMED" and doesn't list a driver. This is similar to the problem described by this user: https://ubuntuforums.org/showthread.php?t=1314693.
So apparently this problem arises from a device with no drivers attached. The solution given in that thread seems to apply specifically to Ubuntu JauntyJackalope; so my questions are as follows:
- How do I determine which driver/backport/etc to install based on my distro and my network adapter, and can I just install them with
sudo apt-get install? (Ideally I'd like a general way to figure it out in case I want to, say, install Linux Mint instead.)
- Although I can access the Internet to install things with
apt, it's a pain; is there a way to load the driver onto a flash drive and install it from there?
EDIT: As requested, some more terminal output:
