Just upgraded to Kubuntu 21.10 from Win10, need help settipng up wifi

[unknowable]

Wow, thanks everyone for the help! I was waiting for an email on a response and never got one. I'll try these solutions and post back. Thanks again everyone.

I'll assume this is a USB dongle as opposed to an internal card, but at least we might get one of them working
Should, rather

Good catch clay:

Good eye, Claydoh!

If push comes to shove the OP can get a Linux compatible USB wifi adaptor from Amazon. The price ranges from $7 up. Here is a good one.

Because of a lightening incident about 10 years ago I had to use one. Worked great.

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

Bus 001 Device 003: ID 0846:9011 NetGear, Inc. WNDA3100v2 802.11abgn [Broadcom BCM4323]

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 installer for the b43 driver

firmware-b43legacy-installer/focal 1:019-4 all
firmware installer for the b43legacy driver

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.

Hi, and thanks for being available to help. First off, I'm upgrading from Windows 10 64x, and wifi worked fine there. I've been to the Kubuntu Common Tasks page, which first tells you to go to K-Menu - System Settings - Network Settings. I have a System Settings icon on the taskbar, but only System on the menu, and no System Settings under there. When I go to to the System Settings icon on the taskbar, there is a section for Network and it does have a Settings subfolder, but there is no hardware info there. There is a Connections subfolder, but it only lists my wired connection. So System Settings is of no help, not with this info.

If I google "kubuntu AND wifi" (without quotes) I get KDE Userbase Wiki, where I can then navigate to Networking - Wireless. This tells me to go to System Settings - Driver Manager. That tells me that I can use a third party driver and to reboot after installation to load the driver. I did that, but still no wifi. The paragraph ends with, for more troubleshooting, see Wireless Troubleshooting. That tells me to start by running nm-tool too see if it's connected. There is no nm-tool in my build. When I try to run it, I get:

unknowable@HP-Compaq-Elite-8300-SFF:~$ nm-tool
Command 'nm-tool' not found, did you mean:
command 'dm-tool' from deb lightdm (1.30.0-0ubuntu4)
Try: sudo apt install <deb name>
unknowable@HP-Compaq-Elite-8300-SFF:~$ sudo apt install nm-tool
[sudo] password for unknowable:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package nm-tool
unknowable@HP-Compaq-Elite-8300-SFF:~$

No known package. Ok, no big, just continue. That takes me down to Troubleshooting Steps. First step, check to make sure that it's working and recognized. Go to Device Recognition and Operation. That tells me to run "lshw -C network" (without the quotes). That returns the wired ethernet connection I'm using, but no wifi. If no wireless device is listed, the next step, since it's USB, is to identify the device. According to the instructions:

. USB Devices


Like PCI devices, USB devices are identified by their USB ID, a unique number assigned to each device type.

• For USB devices, use lsusb.

And that's all it says. When I run lsusb, it does show both adapters (I only need one), like this:

unknowable@HP-Compaq-Elite-8300-SFF:~$ lsusb
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 005: ID 0846:9052 NetGear, Inc. A6100 AC600 DB Wireless Adapter [Realtek RTL8811AU]
Bus 001 Device 004: ID 058f:6387 Alcor Micro Corp. Flash Drive
Bus 001 Device 003: ID 0846:9011 NetGear, Inc. WNDA3100v2 802.11abgn [Broadcom BCM4323]
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 413c:301a Dell Computer Corp. Dell MS116 Optical Mouse
Bus 003 Device 003: ID 413c:2113 Dell Computer Corp. KB216 Wired Keyboard
Bus 003 Device 002: ID 152d:2338 JMicron Technology Corp. / JMicron USA Technology Corp. JM20337 Hi-Speed USB to SATA & PATA
Combo Bridge
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So I can see the device I want to use, NetGear A6100, and I see it's memory address or whatever, but lshw tells me it's not using a driver.

All the information I've found is outdated or incomplete. What do I need to do to get my wifi working, and how do I make sure that it will continue working on reboot?

_______EDIT____________________________________

Whoops, forgot to add the output from lshw. Here's the relevant output from an lshw command (no parameters):




Hm, it's not showing the pic right. Here's the URL:

Thanks again for any help to a linux noob. I really want to switch away from windoze, but it's not easy sometimes.



______SECOND_EDIT______________________________

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!
