Should these rtl USB devices ‘just work’ ™ or do we need to load a driver / kernel module / run a command?
I presume the intention is to make USB wifi plug and play friendly?
ilfelice: Could you please share the USB ID of your TL-WN725N? I have the same model so why is it working for you but not me? I know its not unknown for manufacturers to switch chipsets without changing the model number so that might’ve happened here?
Wouldn’t this just be equivalent to a “hardware RF switch”? I doubt it makes the device appear or disappear when pressing such a key…
As long as the device is attached to the USB controller at boot time, it should be detected (if it is a supported device.)
OK I’ve got it working. I think it didn’t work on my last attempt because I had it plugged into a USB 3.0 instead of a USB 2.0 port. I’m pretty sure this is the first time I’ve ever connected to wifi under Haiku. Exciting!
2022 YEAR OF THE HAIKU DESKTOP!!!
Just tested an Edimax EW-7811Un N150 Wireless USB Adapter Nano, Version 1 which reports as a RealTek 8188CUS.
It works well which is great news because the laptop’s built in Atheros QCA6174 wifi isn’t supported
After long time pause of using Haiku, i test latest hrev55910(gcc2),
I have TP Link Wifi USB adapter TL-WN723N, is represent as
~> listusb | grep Realtek
2357:0109 /dev/bus/usb/1/0/1 "TP-Link" "TL-WN823N v2/v3 [Realtek RTL8192EU]" ver. 0200
is not working, but its nice that find it,
in Network manager i see “no link”
OK, just bought a $9.99 Tplink TL-WN725N (as linked above), and can confirm that it works perfectly in Haiku. Great work Augustin.
Wow. Cool. My Edimax EW-7811UN Super Mini WLAN USB-Stick (150MBit) does work out of the box. Its a random USB WIFI Dongle that I bought like 9 years ago. Yes. I double checked. 9 years.
My USB dongle is labeled as “SURECOM EP-9001” it seems it has some Realtek chipset inside.
Booted with hrev55916, the green led is blinking but nothing happens, so the Network window reports “No link” (device appears as “rtl81xx/0”).
listusb reports:
0bda:b006 /dev/bus/usb/0/3 “Realtek Semiconductor Corp.” "Bluetooth Radio " ver. 0200
(this is my bluetooth adapter, no further realtek chipset detected, so I assume this dongle is totally unsupported ATM)
Under linux it appears as (sudo lsusb -v):

IIRC RT2573 is a Ralink chipset 
The company was bought by MediaTek so name changed.
Uh, so I was misleaded by the device identification “rtl” which is usually a short for realtek!
Sorry for the buzz!
Have start with the adapter inside or you plug in the adapter after system is started?
Anyone got an AC600 or better adapter to work? I am not sure what the support is like in FreeBSD, there is an RTL8812AU driver but it seems that it is not mainline https://github.com/s3erios/urtwm
Booted the OS with the dongle already plugged in, as waddlesplash suggested.
The driver does not support the “EU”-class devices (not sure what the differences are) unfortunately.
This is a Ralink device, those need a different driver. It’s on my TODO list to look into.
rtl81xx is a Realtek PCI ethernet device, not a WiFi device.
That driver is old. The mainline one in FreeBSD supports 8812AU/8821AU already. I tested with an 8812AU, works fine.
Hmm, actually I was mistaken; it does claim to support 8192EU. The ID for “WN823NV2” is already listed in the driver, so I guess if it is not working, there is some other problem.
My D-Link DWA-172 works. I’m told it has an RTL8811AU chip.
I have a RT2573 card in one of my x86 machines (32 bit) that is not detected. It reports as 0db0:6877 (Micro Star International RT2573). I think RT2573 is supported but perhaps this USB ID is not known?
In RT2573, RT stands for Ralink Technology. I will probably work with rum driver when ported.
Realtek chips names are starting by RTL.
@waddlesplash Thank you very much for all the work you are doing for Haiku and specifically for that one.
I bought a TP-Link with 10 euros and I have wireless for first time. A recent buy but looks like is working good enough. I have seen some disconnections-automatic reconnections sometimes but I have updated Haiku succesfully through it.
Please keep up the good work 
Is your adapter listed on our hardware list?
