Everything you did, down to your final solution, strengthened your knowledge of Linux and make you independent of any gurus. As you've found out, 99.99% of the time someone else on the Internet has solved the problem or left clues that led to a solution. That's why DDG or Startpage is your friend.

Great! Also thanks for posting all your work. Always good to have documentation for the next soul looking for the solution.

Ok I don't see how to mark this post SOLVED, but it definitely is. Moved the computer back to the old room, 1 usb adapter, no wires, works great. Thanks again everyone, and please mark this SOLVED. Thanks.

[Snowhog]

Congratulations on getting to a satisfactory solution.

[unknowable]

Yes, it works!! I unplugged the ethernet cable and rebooted, and now I have a wireless network iconin the tray instead of the wired icon. It immediately connected to the WAP, and I disconnected the other NetGear usb dongle. Everything working great!

Thanks to everyone who made an attempt at helping, you all got me a long way. Even if your instructions didn't work for me personally, I learned a lot about commands in linux. Thank you all.

And mostly, thanks go to oshunluvr. Your page gave me the instructions I needed. I've bookmarked that page, as well as saving a local copy for future use. Thanks again!

Good catch clay:

https://askubuntu.com/questions/1243...worked-fine-in

I THINK THIS DID IT!!!! After reading a bit, I found this on that page:


This circa-2014 driver doesn't operate correctly as we see in your various pastes. Let's remove it and try a better driver:

sudo dkms remove rtl8812au/4.3.8.12175.20140902+dfsg --all
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install
sudo modprobe 88XXau

Your wireless should now be working.


HOLY CRAP!! I didn't do the first line, as I wanted to keep everything I've done (just in case). I did everything after (no reboot), and now wireless access points are showing in the Networks systray app. I connected to my local WAP and everything seems fine. I'm now going to disconnect the wired connection and test it out. If that works, I'll reboot and check. If that works, I'll post here in just a minute. Wow. Cool.

I see two adapters:

Bus 001 Device 005: ID 0846:9052 NetGear, Inc. A6100 AC600 DB Wireless Adapter [Realtek RTL8811AU]

This one might take some work, there are multiple possible drivers, but they do need to be compiled
(DONE)

https://help.ubuntu.com/community/Wi...Driver/bcm43xx

Ok, this one tells me to learn which chipset I'm using with the command usb-devices. That gives me the following:

T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=ff(vend.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

(and)

T: Bus=01 Lev=02 Prnt=02 Port=03 Cnt=03 Dev#= 5 Spd=480 MxCh= 0

I: If#=0x0 Alt= 0 #EPs= 6 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)

I don't see how to tell which chipset I'm using from that, but Ok. Next are a list of drivers based on Vendor ID and Device ID. The only info I have is Vendor, and both tell me 0846. That means nothing on the page you gave me. I have no idea which driver to install.

Ok, that one tells me to install dkms (done), then install the driver:


Installation of Driver
In order to install the driver open a terminal in the directory with the source code and execute the following command:

$ sudo make dkms_install


Open a terminal with the source code? How do I get the source code? Tried installing anyway, got this:

unknowable@HP-Compaq-Elite-8300-SFF:~$ sudo make dkms_install
make: *** No rule to make target 'dkms_install'. Stop.
unknowable@HP-Compaq-Elite-8300-SFF:~$


Ok, that's no help. I need step by step instructions, I'm a windoze user. Sorry, but thanks for trying anyway.

[unknowable]

I had this problem some years ago and the solution involved the first or second package mentioned below. I'm sorry I can't remember more!

b43-fwcutter/focal 1:019-4 amd64
utility for extracting Broadcom 43xx firmware

firmware-b43-installer/focal 1:019-4 all

firmware-b43legacy-installer/focal 1:019-4 all

Alright, Synaptic tells me all 3 are installed. I rebooted, no obvious changes. Nothing new in the tray, and lshw gives me nothing new under network:

unknowable@HP-Compaq-Elite-8300-SFF:~$ sudo lshw -C network

The packages are there, but I don't know what to do with them. On to the next.

Ok, I was unclear that those are just packages to be installed. I checked the first one with google, that's where I got those instructions. I used Synaptic to install them all 3, and am about to reboot. We'll see.

[unknowable]

I see two adapters:

Bus 001 Device 005: ID 0846:9052 NetGear, Inc. A6100 AC600 DB Wireless Adapter [Realtek RTL8811AU]

This one might take some work, there are multiple possible drivers, but they do need to be compiled
https://github.com/morrownr/8821cu

...

I'm trying that first one first. Eventually that one tells me to run an installation script on a downloaded driver:

sudo ./install-driver.sh [NoPrompt]

I tried it like that and it gave me an error on NoPrompt, so I tried it without the NoPrompt (sudo ./install-driver.sh) and it seemed to install. Then you reboot. First thing I noticed after rebooting is that my terminal icon is gone from the panel, and also from Latte, my dock. I found it under All Applications, and it runs fine.


Next it says:

"A file called 8821cu.conf will be installed in /etc/modeprobe.d by default.

Location: /etc/modprobe.d/8821cu.conf"

There is an 8821cu.conf but there are no usable options there, only options to turn on logging or the LED light. It then tells me:


This file will be read and applied to the driver on each system boot.

To edit the driver options file, run the edit-options.sh script.

$ sudo ./edit-options.sh


That doesn't work, looks like a typo in the command line. It gives me this:


unknowable@HP-Compaq-Elite-8300-SFF:/etc/modprobe.d$ sudo ./edit-options.sh
sudo: ./edit-options.sh: command not found
unknowable@HP-Compaq-Elite-8300-SFF:/etc/modprobe.d$


So I tried it with a space, but that didn't get me anywhere. The other instructions only telk about Removal of the driver. Full stop, no further use. I'll try the other two suggestions you listed and get back.

Here is a link for installing a driver for your rtl chip set. In fact, several possible solutions are offered there: https://askubuntu.com/questions/1056291/driver-rtl8811au-for-usb-wifi

[unknowable]

Wifi is often a challenge. Your wifi adapter Broadcom chipset is rather old (2014 from what I can tell) and seems may have never been directly supported using Linux : https://linux-hardware.org/?id=usb:0846-9011

There is or was a "wrap around" solution back in those days called "ndiswrapper" which effectly installed the Windows drivers : https://askubuntu.com/questions/5680.../568118#568118

Unfortunately, the manufacturers of those devices did not see a need to support Linux. You may never get it working.

Wrap around I've heard of, but haven't gotten working yet. The URL you pointed to tells me to update, then run this command:

sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9

That returns:
E: Unable to locate package ndiswrapper-common
E: Unable to locate package ndiswrapper-utils-1.9
E: Couldn't find any package by glob 'ndiswrapper-utils-1.9'
E: Couldn't find any package by regex 'ndiswrapper-utils-1.9'


I tried searching Synaptic for ndiswrapper but got no results. So your instructions need to be updated to be useful to me. Thanks for trying anyway.
