how to use tp-link tl-wnb823n on slitaz 5

Hi everbody,

I just bough an USB-WiFi-Adapter, a TP-Link TL-WN823N.

After I inserted it lsusb shows me

Bus 001 Device 004: ID 2357:0109

I run the kernel 3.2.71-slitaz

Any idea how to make use of it?

Thanks in advance,

Michael Bischof

Re: how to use tp-link tl-wnb823n on slitaz 5

maybe the Ubuntu driver from here helps und you can convert it with tazpkg convert

Re: how to use tp-link tl-wnb823n on slitaz 5

Thank you, @kultex. But this driver must be compiled. With a tazpkg-installation it would not work. Plus: apparently with each kernel upgrade the compilation must be done anew. So if there is no „ready“ tazpkg-solution availabele it saves life time to just try another tool with a better chipset. - This rtl8192eu thing seems problematic: on Q4OS with a 3.16.0-4-686-pae it works. On an Ubuntu installation with the same kernel it is recongnized (with ifconfig -a I can seee a wlan1 device) but does not connect. - Before I spend 2 days of my life on it I will better use said alternative. It is not a slitaz problem anyway.

@ michaelbischof

Without any warranties... Convert and install rtl8192eu-dkms_4.4_all.deb

Ok, thank you, Ceel! I might try it then. But forgive me in case I end up with a lazy solution and just will use another stick then.;-)

@michaelbischof

[c]tazpkg install rtl8192eu-3.2.71.tazpkg[/c]

Open 2 terminals.

Terminal 1 will monitor kernel errors such as missing firmware:

[c]tail -f /var/log/messages[/c]

Terminal 2:

[c]modprobe 8192eu[/c]

List alias if the kernel registers the interface:

[c]ls /sys/class/net[/c]

<= But it is not used!

Whether firmware is missing I cannot check. Beyond my abilities! ;-)

May be it might help.

@michaelbischof

The driver either works or it doesn't.

The rest is up to you, I just compile and package the driver.

There are no firmware errors in the output you posted.

The driver source code came from https://github.com/Mange/rtl8192eu-linux-driver

If you purchase another wifi adapter and it has a realtek chipset, return it for a refund.

Realtek wifi has the absolute worst drivers on linux.

Ralink/mediatek wifi chipsets have the best linux drivers.

@mojo

thanks a big lot agaain!

„There are no firmware errors in the output you posted.“ - Then it seems to be just happenstance. As said before: it works on some partitions, on some it does not.

„Realtek wifi has the absolute worst drivers on linux.“ . Yes, a waste of time then. As a consumer who sees something in the supermarket it is unpleasant: what chipset is in the offered USB-stick you do not see and if you are in a hurry, like in my case, on travel in Vienna, 30' before the shop closed, ...

A driver that must be recompiled with each kernel update is inherently an ill „solution“.

Forgive me for having wasted your time!

Regards,

Michael Bischof

PS.as I see 3 people downloaded your driver: experiences? ;-)

@mojo

But thinking again it seems clear to me that

1. your solution technically works perfect

2. the issue I have is not with making the Stick work but with wpa_supplicant. - The card works but it does not connect. Therefore scanning works, but the connection does not come up.

Thanks for all your efforts!
