WiFi adapter (driver) tests

[ZerBea]

Manufacturers do change chipsets without changing model numbers. Sometimes they add (v)ersion or (rev)vision.
As long as a manufacturer or a company does not consider it necessary to supply drivers to the Linux kernel avoid to buy this products!

To reproduce this tests, all steps are explained below (inclusive command line and result).

Test environment.

targets:

target AP: 08:96:d7:98:e1:9e (does not support PMKID caching)
target CLIENT: 00:e6:2d:02:2a:87
operation frequency: 2457 MHz (channel 10 - 2.4Ghz band)

kernel version (unless otherwise specified):

$ uname -r
6.6.1-arch1-1

wireless regulatory domain:

$ iw reg get

https://www.kernel.org/doc/html/latest/networking/regulatory.html

test procedure:

 1 configure target AP with a PSK  (only done once)
 2 connect target CLIENT to AP
 3 generate WPA-PSK PMK: wlangenpmk (only done once)
 4 stop all services that take access to WiFi devices (only done once)
 5 plug the adapter (all USB devices connected to an USB2 port due to well known USB3 problems)
 6 create target BPF (only done once)
 7 attack target: $ time hcxdumptool
 8 convert the hash: $ hcxpcapngtool
 9 confirm the attack: $ hashcat (hashmode 22001)
10 remove test files

generate PMK:

wlangenpmk -e AP_7272 -p 12345678
essid (networkname)....: AP_7272
password...............: 12345678
plainmasterkey (SHA1)..: 5fe2200af1442a46b81f5b696cfc73783f7f77114f5e694a580c889ea9ee64c1

create target BPF:

$ hcxdumptool --bpfc="(not type ctl subtype ack and not type ctl subtype rts and not type ctl subtype cts) and (wlan addr3 08:96:d7:98:e1:9e or wlan addr2 08:96:d7:98:e1:9e or wlan addr1 08:96:d7:98:e1:9e or wlan addr2 00:e6:2d:02:2a:87 or wlan addr1 00:e6:2d:02:2a:87 or wlan addr3 ff:ff:ff:ff:ff:ff)" > target.bpfc

run attack:

$ time hcxdumptool -c 10a --exitoneapol=7 -w test.pcapng --bpf=target.bpfc

convert hash:

$ hcxpcapngtool -o test.22000 test.pcapng

confirm hash:

$ hashcat -m 22001 --potfile-disable test.22000 -a 3 5fe2200af1442a46b81f5b696cfc73783f7f77114f5e694a580c889ea9ee64c1

remove test files:

$ rm test.*

Important information:
Active monitor mode does not work as expected:
openwrt/mt76#839

This adapter is not working out of the box.
It is mandatory to prevent that the Bluetooth module (btusb) will be loaded:
echo "install btusb /bin/false" >> /etc/modprobe.d/local-dontload.conf

Only if that has been done the WiFi part of the device works as expected:

@ZerBea thank you so much mr mike for your help , i am thinking of getting this antenna from do you recommend something else the only antennas which avialable right now for me is

ALFA 9 dBi gain ARS-N19
ALFA Panel Indoor Antenna APA-M25
ALFA ARS-WiFi6E-M2 2.4 GHz + 5 GHz + 6E Tri-Band  this one is 5 dbi
ALFA Panel Indoor Antenna APA-M04
ALFA Panel Indoor Antenna APA-M25

[ZerBea]

The omnidirectional antennas, supplied with the ALFA adapters are good. There is no need to by an additional one.
There are similar products (panel with RP-SMA connector) from e.g. LogiLink and e.g. D-Link. All of them doing a good job.

If you go for range, take a look at "real" panel antennas (e.g. Delock 88806, TP LINK TL-ANT2414, ...), mounted on a tripod (e.g. photo tripod).

[wellitsmez]

@ZerBea mr mike you mean that i dont need to buy the 9 dpi one ALFA 9 dBi gain ARS-N19 to gain a better range because the one with the device i have is enough ?
i have included the options above due to some (restrictions) ....... it's the only thing that is here actually
if i am looking for a better range which choices do i have from the list a bove mr mike

[ZerBea]

The panel antennas are fine. Range will be better than using an omnidirectional antenna.

As of today, firmware is still missing on OpenWRT 24.10:
#478 (comment)

[strasharo]

Looks like the current status of the bug is "RESOLVED OBSOLETE", does this mean they won't merge it at all?

[ZerBea]

I closed the issue report because I opened a pull request:
openwrt/openwrt#17286
This one is still open and waiting to be merged.

[strasharo]

Tried with the PR above, doesn't appear to be stable for me. hcxdumptool freezes shortly after launch. TP-LINK Archer T2U v3, TP-Link TL-WN823N and ALFA AWUS036NEH work fine on the same setup.

Everything's fine here:

I don't think it's a firmware problem

Looks like this issue is still unfixed in kernel 6.6.xx:
https://bugzilla.kernel.org/show_bug.cgi?id=217205

The entire driver is still marked as unstable:
https://github.com/openwrt/openwrt/blob/openwrt-22.03/package/kernel/mac80211/realtek.mk#L156C1-L179C1

define KernelPackage/rtl8xxxu/description
  This is an alternative driver for various Realtek RTL8XXX
  parts written to utilize the Linux mac80211 stack.
  The driver is known to work with a number of RTL8723AU,
  RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices

  This driver is under development and has a limited feature
  set. In particular it does not yet support 40MHz channels
  and power management. However it should have a smaller
  memory footprint than the vendor drivers and benetifs
  from the in kernel mac80211 stack.

  It can coexist with drivers from drivers/staging/rtl8723au,
  drivers/staging/rtl8192u, and drivers/net/wireless/rtlwifi,
  but you will need to control which module you wish to load.

  RTL8XXXU_UNTESTED is enabled
  This option enables detection of Realtek 8723/8188/8191/8192 WiFi
  USB devices which have not been tested directly by the driver
  author or reported to be working by third parties.

  Please report your results!
