I have just downloaded iso image of lubuntu 20.04 When I set boot sequence to boot into it instead of my internal hard-drive OS which is Ubuntu 20.04, (I decided to try lubuntu version because I have an older model Dell PC that needs a super light OS to function half way decently.. haha)

It's a Dell Latitude e6400 if that information helps at all.

I am semi aware of this exact issue I'm currently having with the ubuntu latest releases and I did fix my connection issues in my ubuntu OS somehow after atleast 2 days worth of troubleshooting and frustrations, but I can't find the answer that solves the problem now with my lubuntu version.

In system information on the BIOS menu I found under device information that the "WiFi Device=Dell Wireless" "Cellular Device=(none)" "Bluetooth Device=Installed" "Intergrated NIC MAC= 00-24-E8-A9-3B-CA" "Processor Type= Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz" "Core Count=2"

In BIOS Menu under "Wifi Catcher", I have it disabled... (But it originally was Enabled at the beginning of my problem.)

"Wireless Devices:" Enabled Internal Wireless WLAN, WWAN, and Bluetooth.

I know a few commands now that I'm going to switch over to lubuntu and run to edit my post here with their outputs for you guys.

I tried connecting to the internet via USB tethering with my Android phone also, and had no luck. It connected for 3 seconds and then shut off and wouldn't connect a second time. I tried bluetooth tethering as well to get internet so I could install the additional drivers that I think helped fix the issue for me last time, but it won't connect via bluetooth either.

I manually entered in what details I could figure out went in the spaces available if I choose to "edit connections" in the network manager tool and then "add" a wifi connection from there.

The broadcom driver I previously had to do install also shows as an additional driver that could be installed, but I can't get connected to an internet connection to see if that will solve my connection issues.

Sorry I know this post is all over the place, I am just trying to provide all the details I can think of to get the quickest solution hopefully here.

Going to log off here and reboot my lubuntu to run a few commands, will be back soon! Please help guys, I'm so lost on what I am supposed to do here lol.

Ubuntu and Lubuntu use the same wireless stack under the hood. Whatever you did before to make your wireless work, you must do *exactly the same* again. When you redicover what it is, write it down -- you will surely need it again someday. Alternately, you can install Lubuntu on your existing system without reinstalling. Or you can use a different wireless dongle that is compatible out-of-the-box with Linux.

You weren't specific as to which ISOs you used for install (now or prior install); all Ubuntu 20.04 Desktop ISOs default to the HWE stack where as Lubuntu 20.04 & 20.04.1 default to using the GA stack; however Lubuntu 20.04.2 & later default to using HWE like Ubuntu media does is the only difference that I'm aware of between them (beyond using different desktop, software stacks [GTK3 vs Qt5] on top of the same Ubuntu base). None of that should make any difference though as user535733 already stated; but can mean you have switched to a different kernel via re-install.

FYI: I QA-test Lubuntu installs (currently focus is on 20.04.3 media primarily, but also *impish*) and regularly install Lubuntu over prior Xubuntu/Ubuntu/Kubuntu QA-test installs (including no-formats where files remain) and issues would not be expected. Since your wifi required extra *steps* post-install to operate in Ubuntu, I'd expect those steps likely to be required in the re-install (of different *flavor*); depends on what is required (system directories are wiped; so configs on those directories will require re-doing; depends on what you needed to do to get wifi working)

Edit your question and show me: when booted to Ubuntu `dkms status` and `sudo lshw -C network`, when booted to Lubuntu `sudo lshw -C network`. Start comments to me with @heynnema or I'll miss them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
