[SOLVED] How to install Realtek wifi driver on Debian

As for uploads, I'd agree. Except for downloads, with the usb dongle, it's easy to optimise your aerial position.

It's not to be sniffed at. One day here, I managed to speed up a download stream from ≅4Mbps to ≅25Mbps on a RazPi simply by adjusting position & orientation. I'm now on ≤60Mbps on the same device by swapping out the internal wifi for a usb dongle,(≤50Mbps) then a mains network adapter.

The problem here is the router is one floor below my room, I can get about 10% more signal with the dongle than the internal adapter, and I can move the dongle around with extension cable to get the best signal. Unfortunately the dongle with antenna does now work without the correct driver so can't compare, and I have no control of the router and range extender is out of the question.

My router is on the floor below, and it'd not a problem. What you need is a working driver. I'km sure you'll be cautious about chipsets and drivers if you have to buy again.

Less reputable names are: Realtek; Mediatek; Ralink; TP-link;Cypress(bought by Broadcom) at least provide firmware & drivers. My favourite is Qualcomm.

Thanks for the tip, I copied the firmware to the folder but nothing happened, there are still works to do I know... on the other hand I tried FreeBSD and it recognized the Realtek on first boot !

Look, joboy, the dictionary is the only place where "success" comes before "work."

In /boot, there should be a file config-<version>. grep that for your chip

Code:

grep -i 8812au /boot/config-*

You copied the firmware - great. Did you work? Did you build the driver? Did you read and follow the instructions. In debian, you will have to install build-essential(s) first.Download morrownr's driver, build it and let us know how it works.

You need to install the drivers not just copy them across, follow the instructions;

If it is this chip, 8812au or 8821au is the wrong driver.

See my post #5.

Also read the readme on the git Repo.

I posted in post #10 only, how the kernel is using the right driver for my TP-Link Adapter.......

Most of the drivers there are now in the rtw88 driver from wireless next, see:
https://github.com/lwfinger/rtw88

So with newer kernel Version, they are supported natively.

Thank guys, I follow that part and worked

Now I got the same reception as the onboard wifi, but at least I can move around the adapter to get better signal.
