I am trying to use Linux instead of Windows for the first time. I tried 11 (Eleven) installations of Debian 9.6 and had no success connecting to WiFi. I used the Firmware that was not included due to open source issues. It said the driver was installed already but needed the firmware. I accomplished nothing except wiping out my hard drive trying to partition it using Debian. I purchased a DVD/CD from OSD for this.

Then I thought, let me try Ubuntu as it is supposed to include newest drivers - WRONG. lol

I installed (many times) Ubuntu 18.04.1 LTS. It still did not recognize my PCI card. Next, I purchased a USB wifi adapter known to work with LINUX. WRONG AGAIN. I have tried every "Ask Ubuntu" post as well as Google search. Either it doesn't work, or the post has NO IDEA what it's like to be a Noob. I have no idea what they are talking about.

Facts: Computer Desktop Lenovo ideacentre 300 - 20ish, 8GB Ram, 1 TB HD, was Windows 10, no longer. PCI Wireless Network Adapter - realtek RTL8821AE 802.11ac USB Wifi - tp-link AC1300 High Gain Archer T4U OS - Linux 18.04.1 LTS

Under Software & Updates shows Additional Drivers - Using dkms source for the r8821au network driver from rtl8812au-dkms (open source).

I entered lspci -nnk | grep 0280 -A3 and nothing happened. I then tried it as two separate commands and this happened after entering lspci -nnk:

michael@michael-ideacentre-300-20ISH:~$ lspci -nnk | grep 0280 -A3
michael@michael-ideacentre-300-20ISH:~$ lspci -nnk | grep 0280 -A3

I then entered just grep 0280 -A3 and got the new prompt above.

G'day Michael, and Welcome to Linux.org

If you have access to an Ethernet cable pop it in the machine then open terminal and type in: sudo apt-get install bcmwl-kernel-source
 
G'day Michael - I'm another Aussie, like Brian, above, welcome also :). I'm September 27 1957. We won't say how old Brian is, dog years or other.

My goodness you have been in the wars, haven't you?

Points for perseverance :), and thanks for all the output, we can always use it.

See how you go with Brian's suggestion, and if no go, we'll see what magic we can rustle up.

Friday here in Oz, so

Avagudweegend, all ;)

Aussie aussie aussie. Thanks.
 
Aussie ... oi ...Aussie .... oi .... Aussie ....oi .... Aussie Aussie Aussie oi oi oi oi :D:rolleyes:

Morning all, now what have I missed?

Michael - Mate either or both of those two (2) links @arochester has provided may well provide a working solution, they appear at face value to be right on the money, as I would expect of him :)

Peer said:
Install "Firmware-iwlwifi"
Click to expand...

... was not a bad call, @Peer :), given what Michael had told us, but does not apply here.

I am guessing Michael has found an article such as this , where that User has those circumstances.

In Michael's extensive output, he included

Code: 
lspci -nnk | grep 0280 -A3

... and that would provide an output, were he in need of iwlwifi.

In fact, better would have been

Code: 
lspci -nnk | grep 0280

... which in my case provides the following

Code: 
[chris@MJRO-Xfce ~]$ lspci -nnk | grep 0280
03:00.0 Network controller [0280]: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter [168c:0042] (rev 31)

As you can see from my prompt, I am in Manjaro at the moment, but I can swing over to an Ubuntu if need be.

So see how you go with arochester's offerings, and I'll be around during my day ;)

Cheers

I checked BIOS and wifi is enabled. I ran the following:

Thanks for all the help so far. Response is amazing.
 
G'day Michael.

1st up, can you give me the output of

Code: 
lspci -nnk | grep -iA2 net

Mine looks like this

Code: 
chris@Tara-Cinnamon-SSD:~$ lspci -nnk | grep -iA2 net

... Highlighting is mine.

If you don't have output on the Network Controller, don't be disappointed ... yet :(:eek::D

I may be onto something, not sure yet.

Ta (pron. "tar" Aussie for thanks) for your patience.

:oops: Oops, you are new to this :)

It's on my list to do up a Thread on Posting here.

On your Reply Pane toolbar 4th from right is an icon with a plus sign + in a square/oblong.

Clicking that reveals options including "Code".

With it, we can put the commands we suggest to you, and you, the output you give us back, in a neat format that is easy for us to cut and paste and respond.

If we put a #, it is a comment or remark, and not a command to be typed.

So with your above:

Code: 
michael@michael-ideacentre-300-20ISH:~$ Code:
Code:: command not found

# Not really a command to be typed, it is just the code field

michael@michael-ideacentre-300-20ISH:~$
michael@michael-ideacentre-300-20ISH:~$ lspci -nnk | grep -iA2 net
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)

Kernel driver in use: r8169
Kernel modules: r8169

You'll pick it up quickly, I am sure :p

When you give us the output, you can include in the copy and paste your prompt (user id ending in ~$) and the command too, just as I have in mine, above, then we can see that you got the syntax of the command correctly.

Thanks for that output.

So Ubuntu is definitely not getting your Network Controller info, just the Ethernet cable stuff, and I expect the same applied to Debian.

Sweet, we'll go from there.

I have to scoot for my Saturday evening and I'll be back on deck tomorrow. But I do not have a mortgage on knowledge at this site, so if someone else comes along with a good idea in the interim, don't wait for me :D

Cheers

Morning all :)

Michael when you get a chance, did you install the GNOME desktop version or the MATE?

If you are not sure

Code: 
echo $DESKTOP_SESSION

... will reveal "ubuntu" or "mate".

It says Ubuntu, which is what I installed - Gnome.
 
Thanks for your help.

I ran the lsusb command and got back:
0bda:0821 which says the chipset is for "Realtek Bluetooth 4.0 Adapter"
I checked that the bluetooth is disabled in case they shared the connection(?) and rebooted but still no wifi adaptor found. The rest of the article did not cover 8812ae.

Attempted all fixes with no change. It shows my chip set to be a Realtek 4.0 Bluetooth adaptor. I disabled bluetooth to see if they were both trying to connect(?). No luck. It did show a soft block but it made no difference.

michael@michael-ideacentre-300-20ISH:~$ iwconfig
lo no wireless extensions.

eno1 no wireless extensions.

Did you autoremove the old kernels, or leave them in place? If you didn't ... don't :)

I have a feeling that this is a combination of :

  • Linux kernel in use
  • Lenovo (we get many problems from them) and
  • Realtek
... as a combined issue.

Since your Windows got wiped, do you still have a Grub Menu at startup, or does it boot straight in to Ubuntu?

If the latter, I would like to make your Grub Menu visible at all startups.

When I am responding to this Thread, I am using your 'buntu GNOME, hence my asking before which DE. That way I can better direct you if we need to do something with the GUI side of things.

Cheers
