4 years ago This driver, which claims to be 5.8.5 does work at 469 Mb/s: https://github.com/coolshou/rtl8814au

# rmmod and make uninstall or ./dkms-remove.sh of whatever was there before
cd ~

aircrack-ng is broken somehow but did take code from this repo
Now, gentlemen, you have a working and a failing case, and we know it can be done!

Applying that patch removes the crash but does not increase throughput. Bug still there

4 years ago @haraldrudell Yeah, finally a more clean driver for that chipset also, rtl8812au and rtl8821au is quite similar, rtl8814au code never was..
@fariouche Here's some news for us 🥇
The import commit is found below, seems legit, checked history for rtw_version.h tampering, but it seems it's a vendor release, not pure Realtek but it looks good!

4 years ago Ok, this is a driver developed by Edimax actually. Vedpr based.
Here's the link to ZIP below; https://www.edimax.com/edimax/mw/cufiles/files/download/Driver_Utility/EW-7833UAC/EW-7833UAC_linux_5.8.5.1_kernel_2.6-5.1.zip
What I'll do, I'll compare it to the past release of 8814au and see what changed. Damn!

4 years ago Realtek rtl8814au from 2010 is Wi-Fi 5 802.11ac 4x4:3 AC1900: 1.3 Gb/s on 5 GHz 80 MHz and 600 Mb/s on 2.4 GHz 40 MHz
That makes it the fastest usb chip at present until 4x4:4 or Wi-Fi 6 802.11ax is available. And it is supported or at least working on Linux/macOS/Windows. The maximum speed calls for a usb3 port at 5 Gb/s or better
At least for Linux, Access Point and Wi-Fi Direct is supported, too. That means we have a dual band eap-tls or wpa3 with continuous security updates
NETGEAR A7000 seems to have put the best antennas on it but there are many like: D-Link DWA-192, Edimax EW7833UAC, TP-Link Archer T9UH

4 years ago Some additional differences:
Neither driver supports multiple ssids: iw list interface combinations are not supported
The coolshou driver does not have the radar detection channels 52…144 but has channels 144…177 disabled, 14 disabled
coolshou driver does not have: HT 2.4/5 GHz: RX Greenfield RX STBC 3-streams VHT 5 GHz: > [RX-STBC-1] ie. the coolshou driver does not: — offer non-backwards compatible, higher performing HT channel: 2.4 GHz 802.11n performance — receive multiple spatial streams
coolshou does not have command: set_wiphy_netns
The conclusion is, as of October 17th, 2020: use 88XXau for AP use 8814au for STA
haraldrudell
commented
4 years ago I am not sure if those software capability descriptions is what the hardware is actually doing
The coolshou driver could receive at 469 Mb/s on 5 GHz as verified by iperf3. That speed will only be attained when using all 3 spatial streams

4 years ago It seems that SAE WPA3-Personal does not work as STA or AP 8814 does not have protected management frames, but does have SAE iw list … MFP-capable # is missing Device supports SAE with AUTHENTICATE command
Because the driver has no combinations, multi-band AP or multi-ssid authentication like guest network is unavailable
haraldrudell
commented
4 years ago For reference, here is iw list output for the 88XXau aircrack-ng driver and rtl8814au. This data can be difficult to come by
— multiple ssids is not supported “interface combinations are not supported” so multi-band AP or guest network involves adding more adapters — protected management frames is not supported 802.11w, so it will not work with certified WPA3 hardware that will reject this device: iw list “MFP-capable” — SAE, ie. WPA3 authentication, is supported “Device supports SAE with AUTHENTICATE command” — — SAE is as of now the only safe password-based Wi-Fi of any kind — — SAE makes password attacks unfeasible for passwords that are difficult to guess — — SAE mutually authenticates STA and AP like eap-tls, they must both prove to have the secret — — Wi-Fi security that is not eap-tls prior to 2018 is garbage as is much embedded software out of China
There are no mfp usb adapters for Linux as of yet Recent built-in pci chipsets offer mfp, for example the Raspberry Pi 4’s Broadcom
The best use of this AC1900 hardware is 469 Mb/s browsing throughput on 1.3 Gb/s 5 GHz 80 MHz eap-tls. We’ll all enjoy very safe amazing performance. No known vulnerabilities whatsoever since 0 BC
