hcxdumptool poor injection ratio - slawson - 01-12-2023 I am using an Asus AWUS036AC adapter (Chipset RTL8812AU). I also upgraded the antennas to 10 dbi. The card gets excellent reception. Although, when using hcxdumptool, it is not performing very well (I don't think). I ran hcxdumptool -i wlan1 --do_rcascan and it only hits about 7-9% injection ratio. In comparison my cheaper TP-Link WN772N, which doesn't have near the range as my Asus, seems to perform much better on picking up PMKIDs. Is there anything I can do to improve the injection ratio? Thanks for any insight. RE: hcxdumptool poor injection ratio - ZerBea - 01-13-2023 Realtek chipsets are not recommended to be used in combination with hcxdumptool/hcxlabtool due to their NETLINK dependency (README.md). Code: Adapters Also it is not recommended to use high TX power devices, because it doesn't make sense if you transmit with 1000mW RF power and your target only transmit using 100mW TX power. It is much better to use a high gain antenna in combination with a low TX power device. Antenna gain is cheaper and more efficient than power gain. Power gain may increase range only in transmit direction, but in every case antenna gain increase range in both directions (transmit and receive). Antenna theory and transmitter theory and the practical use of both forms the core of the injection radio. There is a trade off between both: Increasing your TX power doesn’t raise the level of the received signal on the same unit. Increasing antenna gain whilst decreasing TX power of the adapter results in a greater range. RE: hcxdumptool poor injection ratio - ZerBea - 01-13-2023 This may help to understand the theory: https://www.rfwireless-world.com/calculators/Antenna-Range-Calculator.html BTW: There are some more competitors in the range game like frequency and speed: Increasing the frequency will decrease the range, because antenna gain is absolutely affected by frequency. Increasing the speed will decrease the range. RE: hcxdumptool poor injection ratio - slawson - 01-13-2023 That is very interesting and informative. Thank you for taking the time to explain it. I have tried many different adapters/antennas. Do you have an adapter and antenna that you recommend? Also, just curious, but does the same principle that you explained above also apply to methods like obtaining handshakes with airodump-ng? RE: hcxdumptool poor injection ratio - ZerBea - 01-13-2023 Yes I have: https://github.com/ZerBea/hcxdumptool/wiki/Penetration-testing-system-2 https://github.com/ZerBea/hcxdumptool/wiki/Penetration-testing-system-1 https://github.com/ZerBea/hcxdumptool/wiki/Penetration-testing-system-4 https://github.com/ZerBea/hcxdumptool/wiki/Penetration-testing-system-5 and some more adapter information here: https://github.com/ZerBea/hcxdumptool/wiki/WiFi-Adapters MediaTek (former Ralink) and Ralink chipsets are fine. Both drivers (rt2x00 and mt76) are part of the Linux stock kernel and well maintained. ALFA AWUS036ACM ID 0e8d:7612 MediaTek Inc.

RE: hcxdumptool poor injection ratio - ZerBea - 01-14-2023 Both devices mentioned above are high TX power devices, but they are powered down (20dBm instead of possible 30dBm) by wireless regulatory domain: Code: $ iw reg get hcxdumptool and hcylabtool respect this (crda) settings: Code: $ hcxdumptool -I TX power on ch 14 is set to 0, because using this channel is not allowed in the EU: 2484MHz 14 ( 0 dBm) Also you should know that the RTL8812AU driver is not(!) part of the Linux kernel: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/realtek?h=v6.1.5 It is a third party driver from here: https://github.com/aircrack-ng/rtl8812au You can follow the problems here: https://github.com/aircrack-ng/rtl8812au/issues I know the maintainer and he really is doing his best on this driver, but unfortunately he is too busy to work on it constantly. RE: hcxdumptool poor injection ratio - slawson - 01-14-2023 Thanks again. I have learned a lot. I would like to get a TENDA W311U+, but I don't see one available online. Do you have another suggestion with a current available model? RE: hcxdumptool poor injection ratio - ZerBea - 01-15-2023 These days it is not easy to buy something like that. Most vendors sell cheap devices running Realtek chipsets. Most manufacturers change chipset but do not change packaging and order number. You have to look twice, before purchasing such a device. Just search for: mt7610u mt7601u rt5370 https://duckduckgo.com/?q=mt7610u&t=ffab&ia=web https://duckduckgo.com/?q=mt7601u&t=ffab&ia=web https://duckduckgo.com/?t=ffab&q=rt5370&ia=web Do not buy this ultra cheap ones (neither mt76 nor rt5370 devices using this case): https://ricelee.s3.ap-northeast-1.amazonaws.com/wp-content/uploads/2018/05/11175345/Ralink-RT5370-150M-USB-Wifi-Dongle-1.jpg RE: hcxdumptool poor injection ratio - ZerBea - 01-16-2023 Just noticed this driver update and the first impression is quite good: https://github.com/kimocoder/realtek_rtwifi/issues/34 Let's see how the device (in my case a cheap TP-Link TL-WN722N v2/v3 - Realtek RTL8188EUS chipset) performs in further going tests. |
