【Good news】I successfully use five wireless dongles of 4 chips on VisionFive 2

HonestQiao · January 21, 2023, 3:15pm

I have five wireless dongles:

They are:

RTL8192CU：“EDUP” in the first picture
MT7601U：one is “Mi” in the first picture，second is “du” in the first picture
ECR6600U：the green dongle in the first picture, Officially provided.
RTL8832AU：“EDUP” in the second picture

In these wireless dongles, both ECR6600U and RTL8832AU support WiFi6.
ECR6600U supports 2.4GHz. RTL8832AU supports 2.4GHz and 5GHz.

I successfully use these five wireless dongles on VisionFive 2.
My system is Debian image69.

Because I am a Chinese user, I wrote a post in Chinese to explain how to use these USB wireless dongles.
The url is https://forum.rvspace.org/t/2-usb-rtl8832au-wifi6/1595.
Maybe you need to use Google Translate to help you to view.
I will arrange time to write an English document.

Today is Chinese New Year, My best wishes to everyone.

(Bad news)
Just tried your write up for the ECR6600U (again).
Still does not work.
Driver compiles, but is very unstable (repeated password prompts + stack traces galore).
Not useable.

When ecr6600u is connected to the board, two network devices will appear.
One is for normal mode, other is for WiFi-Direct.

You can try these steps

# unplug ECR6600U, then plug in ECR6600U
dmesg | grep -Ei 'wlan|p2p'

The device with “…p2p0…” is WiFi-Direct
The device with “…wlan…” is for WiFI-Normal.

If you want to connect to WiFi router, you need to use the device for WiFI-Normal.

Thanks for the information.
I am travelling at the moment. I will give your suggestion a try later in the week.

I can add in that the Atheros AR9271 works with the open source firmware-ath9k-htc package, a fitting match to the open nature of this project

After loading the ecr6600u driver, did you managed to connect to a 2.4GHz WiFi with WPA2?
Did you use wpa_supplicant?

HonestQiao · February 26, 2023, 1:38pm

I use nmcli command:

# config
sudo nmcli device wifi connect YOUR-SSID password YOUR-PWD ifname wlan0 &

# autostart
sudo nmcli connection modify YOUR-SSID connection.autoconnect yes

@HonestQiao is correct; while many of us are familiar with Pi-Based instructions about directly editing wpa-config, dhcpd.conf etc. It’s not the best way to do it anymore.

For recent systemd based distros the correct way to configure networking on the CLI is with nmicli, this will update the lower level config files correctly and restart services as needed.

You don’t have to like systemd! But if working with a distro based on it you really need to learn to use it properly, otherwise you lose time and sanity fighting it.
This is why non-systemd distros exits, for those who like to hand edit config files without having somebody else’s tooling messing it up. (I run a from-scratch-bootstrapped FreeBSD for my home server, which is perhaps taking this to extremes)

No folks, I don’t recommend buying any WiFi dongles with the RTL8832AU chip.

## USB WiFi adapters with Linux `out-of-kernel` drivers

The below listing of drivers and chipsets is ranked in order by quality of driver with best at the top.

The best overall Realtek out-of-kernel drivers currently are the the 8821cu (8811cu and 8821cu chipsets), the 88x2bu (8812bu and 8822bu chipsets), the 8812au, and the 8821au (8811au and 8821au chipsets).  These drivers perform well in all modes that I regularly test. I concentrate my testing on client (managed), master (AP) and monitor modes. The fastest of these drivers is the 88x2bu (with 8812bu chipset).

My advice, for Linux users needing to buy a new adapter, is to give preference to Mediatek chipset based adapters because the Mediatek drivers are based on Linux Wireless Standards (mac80211) and are maintained in the kernel. This makes the Mediatek based adapters much more troublefree in the long run.

If you are unable to find an adapter based on Mediatek chipsets, then I recommend adapters based on these chipsets (in order): 8811cu, 8812bu, 8812au,  and 8811au. I currently recommend you AVOID adapters based on the Realtek 8814au, 8832au, 8852au, 8832bu and 8852bu chipsets as the drivers are not good and I also recommend you AVOID adapters that are multi-state, and multi-function (wifi and bt).

Note: The below sections provide links to drivers and a lot of information. Ten total chipsets are supported with the listed five drivers.

-----

Recent changes:

- 2023-02-01 - moved 88x2bu higher in the list due to recent improvements
- 2023-01-31 - add new version of driver for the rtl8811cu, rtl8821cu, rtl8821cuh and rtl8731au chipsets (MU-MIMO support)
- 2023-01-30 - add MU-MIMO support for rtl88x2bu driver (new capability)
- 2022-12-01 - added rtl8832bu test results and recommendation

chipset - rtl8832au / rtl8852au - AX1800 - USB 3

No driver is posted for this chipset.

The rtl8852/32au chipset was the first AX class chipset that was available for use in USB WiFi adapters. Unfortunately, Realtek decided to support it with an out-of-kernel driver on Linux instead of doing the right thing and providing a mac80211 technology in-kernel driver. I tested the provided driver (v1.15.0.1). The results were terrible. As many of you know, I have a lot of USB WiFi adapters that I use and test. I cannot recall an experience as bad as this and I have been using USB WiFi adapters for many years. I experienced numerous system lockups that required me to pull the plug to get things going again. Additionally many features are simply not working. Power saving does not work. DFS channels do not work in AP mode. WPA3 did not work in any mode. I saw problems in basic client mode that I cannot explain. The driver is VERY BAD. Avoid adapters based on the 8852/32au chipset.

The Good:

Nothing.

The Bad:

A long list of bad.

The adapter I tested is multi-state and it appears that most adapters that use this chipset are multi-state. Not good.

Recommendation: AVOID adapters based on this chipset. You will be disappointed. The driver is an out-of-kernel driver that is not consistent with Linux Wireless standards and it is a terrible driver. Recommend Linux uders seek out usb wifi adapters that use the mt7921au chipset if seeking an adapter that is WiFi 6 capable.

Over the night, ECR6600U disconnects from the WiFi. To reconnect, I have to do ifconfig down and ifconfig up. The router (Tenda AC15, FreshTomato 2022.7) sees the WiFi signal, but packets are not received by ECR6600U (I have a serial cable connected, tcpdump on VisionFive2 does not see ping packets sent from the router).

Now I’m playing with a rtl8822bu (USB D-Link Corp. 802.11ac).
The folder /media/vision/VisionFive2/linux contains a kernel compiled for ECR6600U using @HonestQiao tutorial in chinese. This is a native compilation on the VisionFive 2 board.

I’m a beginner. Some of the steps above might be wrong. But the WiFi works.
