Realtek rtl8821au driver

[netfrog77]

Hi fellow Puppy users.

My wireless adapter for my Tahr Puppy powered machine just died.
Ordered a new USB adapter hoping the driver would already be in Tahr Puppy as the last USB adapter worked just fine out-of-box.

No such luck. Does anyone have information on a driver PET for the rtl8821au?

Thanks

It really does help everybody out now and in the future if you supplied
the exact model number and name of your device.

" new USB adapter >>> rtl8821au "

Didn't realize the name/model of the adapter would make a difference as far the the driver for the chipset driver was concerned, but here it is. Hope it helps.

Thanks for your response!

Run the command "lsusb". Identify the vendor:product ID codes for your device.

Guess this must be it:
Bus 001 Device 003: ID 0bda:0811 Realtek Semiconductor Corp.

[rcrsn51]

Your 0bda:0811 device is handled by the 8812au driver here.

If your Tahrpup has kernel version k3.14.56, you can use that PET directly. Otherwise, you will need to do a kernel-change procedure.

Thanks for the driver info.

Tahr ISO is 64-6.0.5

How do I determine the version you mention?

[rcrsn51]

You can find the kernel version with the command "uname -r".

But you must be clear on whether your Tahr is 32bit or 64bit.

[netfrog77]

Kernel is 3.14.64, x86.64

Thanks for command info.
I have looked at the post for the driver, but finding it a bit confusing so far as I have not attempted anything like this before, just simple pet loading.

[netfrog77]

Oops: 3.14.54 - clearly my keyboard skills are also limited.

Hi rcrsn51,

Expect the "8812au_tahr64_gnab-k3.14.54.pet" would work for me.

but can't find the download at the link your provided here:

[Updated 2017-04-09] This is the next-generation AC600 driver for devices like the Edimax EW-7811UTC. AC600 claims to be up to 3X faster than N-mode, assuming that you have an AC600 router. In an N-mode network, I have not found this device to be any better than standard drivers like 8192cu. YMMV.

The 8812au driver is not present in any current mainstream kernel. However, there is a modified vendor driver from here that compiles in many Puppies. I have built a selection of PETs and packaged them in a single tarball.
Code:
8812au_fatdog64_710_gnab-k4.4.35.pet
8812au_precise_571_gnab-k3.9.11.pet
8812au_slacko_630_gnab-k3.14.55.pet
8812au_slacko64_gnab-k4.1.11.pet
8812au_tahr_605_gnab-k3.14.56.pet
8812au_tahr64_gnab-k3.14.54.pet

Download it from here. Click the green DOWNLOAD box.

Extract the package and run the PET for your system.

Be aware that these drivers are kernel-specific. They will NOT run in alternate Puppies like no-PAE.

Can you provide an updated link to the file?

Thanks

I don't know where you are reading, but that's an old page.

The current page is at the link I posted above.

It's the thread directly underneath this one.

I have added a PET to the tarball specifically for tahr64-605. So you don't need to do a kernel-switch.

[netfrog77]

Thank you so much for your assistance!!
My tahr puppy machine is up and running!

[rcrsn51]

And thank you for working through this.

It wasn't clear to me whether the RTL8821AU chipset would be handled by the same driver as the RTL8812AU chipset.
