How to use AC600 (Realteak RTL8192CU) wireless adaptor?

[nfkhanh]

Hi all!
I installed F96-CE_4 on my Lenovo M93P desktop with AC600_free_driver wireless adaptor. F96-CE_4 maybe does not have driver for this wireless adaptor. On Windows, I follow the link inside this adaptor free folder and I downloaded its driver. The link is https://bit.ly/2tsbuS7. I don't know how to compile the necessary driver for F96-CE_4. Is there anyone who can show me the way to compile or help me to have an available driver (the best is post-complied driver)?
Because the driver I downloaded is big with above 120MiB, so I cannot attatch it with this post.
Thank you so much.

Most likely your adapter does NOT support Linux system.

@nfkhanh

Which brand is this adapter?

Also, what is provided in the file you linked to?

share a screenshot

When you plugin in the device, open up terminal and enter this:

lsusb

once again share the results.

AC600_free_driver

This is just something that the anonymous Chinese vendors stamp on their no-name adapters. It doesn't tell you anything specific about the driver.

However, many AC600 devices are now supported by the bleeding-edge kernels. Have you tried this device in newer Puppies?

[nfkhanh]

Thank you for your supports.
These are some informations of the adaptor:
1. Image of the adaptor.
2. Name of adaptor: Free-Driver-USB-Wifi-Adapter-PC-AC600M-Dongle-802-11ac-Wireless-Network-Dual-Band-2-4GHz-5Ghz.
3. Name of the dowloaded driver: RTL_Driver_V1.5.zip
4. Readme.txt.

@rcrsn51

My screenshot was for illustration purposes.

[rcrsn51]

My mistake. We are still waiting for the correct lsusb.

[nfkhanh]

This is the screenshot.
In Bus 003 I think this is anaother wireless adaptor which is supporting.
Under lsusb I cannot see AC600.

This looks to me like your AC-mode rtl8821cu adapter. It is one of these strange dual-mode devices that starts off in WIndows mode in order to install the driver. It needs usb-modeswitch to switch it to Linux. This doesn't appear to be working in F96-CE.

[nfkhanh]

Thank rcrsn51.
Here is screenshot.

[Jasper]

Try this command in terminal

lsusb -v | grep -E '\<(Bus|iProduct|bDeviceClass|bDeviceProtocol)' 2>/dev/null

this should give you more detailed information

@nfkhanh

What software application are you using to connect to the internet?

The 'network' icon on the right hand side of your tray shows you are connected.

3. Name of the dowloaded driver: RTL_Driver_V1.5.zip

It includes the file 'ReleaseNotes.pdf'

Thanks @FeodorF

The PDF states:

This looks to me like your AC-mode rtl 8811cu/8821cu adapter. It is one of these strange dual-mode devices that starts off in WIndows mode in order to install the driver. It needs usb-modeswitch to switch it to Linux. This doesn't appear to be working in F96-CE.

The rtl8192cu must be an n-mode adapter that you also have plugged in.

[rcrsn51]

According to my notes, you would need to run the command: usb_modeswitch -K -v 0bda -p 1a2b

This should switch the device into an rtl8821cu wifi adapter, which should now appear under lsusb.

You will now need the matching driver, which F96-CE probably doesn't have.

@Sofiya This issue has nothing to do with rtl8192cu.

[Sofiya]

Check the driver with the ls command:

Code: Select all

ls /lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtl8821cu

Always good IMO to write something about the reason why you edited a post as a moderator.
Rather than leave it empty as you did:

You can copy text from a terminal and paste it into a post.

Here is how:

Do this instead of making images of the screen.

So is anyone going to change it back to something that makes sense? We still don't know for sure what the correct driver is.
You could at least spell Realtek correctly.
Jeez.

It was me. As you can see from the second post in this thread, the original title was "Wireless adapter," which didn't give as much information as it could have. It wasn't even a question. Someone who was searching the forum for a driver for their wifi adepter would have to read down a ways to find out if this thread was about their adapter. Someone who knows a lot about wifi drivers would have to read down a ways to find out if the thread was about an adapter they know about. I thought it should be easier.

As I've said several times before, my main goal as a moderator is to make this forum as useful as possible. That means helping the people who answer questions, and the people who search the forum for answers. So when I see a post with a subject line that could indicate more than it does about the thread, I try to improve it so that it will attract the notice of people who might be interested in the thread. Sort of like the headline of a newspaper story, but stopping short of clickbait.

In this case, I read down this thread until I came to Jasper's post here. Assuming it was correct, I copied what I thought was relevant and added it to the subject line of the original post, intending to attract the notice of anyone who might know the driver for that particular wifi adapter, but also anyone with that adapter who was trying to make it work in Puppy Linux.

As regular users of this forum may have noticed, it's rare when someone thinks to add "Solved" to the subject line of the original post of a thread, so I do it when the question seems to have been answered. I don't always get it right.

I rarely edit the contents of a post, and only to correct obvious spelling and punctuation errors, never to change the meaning.

Hi all!
Calm down everybody.
Listen to Mark Knoffler.
Forget the adaptor.
"Brother in Arms"
"These mist covered mountains
Are home now for me".
Hence I love Puppy
An OS so pretty
For it, I shall forgive
It's not fault from me.
Cause that Puppy is still a Puppy.
...Todas ustedes son sympáticas.

So you never tried my usb_modeswitch suggestion? This could have been useful information to other community members.

I've tried with your recomment. I see there is a difference. But I've not understood yet. And AC600 has not been accepted by F96-AC_4. I'll try again when I'm free.
Thank you so much.
