Hi!

I can get cheap old Alfa AWUS036H 802.11b/g for learning purpuses. As I understand things modern wireless routers use at least n standard which that old usb modem does not support. Will that alfa be able to monitor newer routers or not? Package injection on n network probably wouldnt work?

Thx

Working fine on Linux operating system (mandatory) and hcxdumptool/hcxlabtool series.

Chipset Realtek RTL8187
Code:
$ lsusb
ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Please notice that two different chipsets are manufactored:
https://wikidevi.wi-cat.ru/ALFA_Network_AWUS036H
Make sure it will get the RTL8187 one!

Full support on all 2.4GHz channels:
Code:
$ sudo hcxdumptool -i wlp5s0f4u2 -C
initialization of hcxdumptool 6.2.5-29-gf5b28d0...
wlp5s0f4u2 available frequencies, channels and tx power reported by driver:
2412MHz   1 (20 dBm)
2417MHz   2 (20 dBm)
2422MHz   3 (20 dBm)
2427MHz   4 (20 dBm)
2432MHz   5 (20 dBm)
2437MHz   6 (20 dBm)
2442MHz   7 (20 dBm)
2447MHz   8 (20 dBm)
2452MHz   9 (20 dBm)
2457MHz  10 (20 dBm)
2462MHz  11 (20 dBm)
2467MHz  12 (20 dBm)
2472MHz  13 (20 dBm)
2484MHz  14 (20 dBm)

terminating...
depending on your wireless regulatory domain settings, e.g:
Code:
$ iw reg get
global
country IN: DFS-UNSET
    (2402 - 2482 @ 40), (N/A, 20), (N/A)
    (5150 - 5250 @ 80), (N/A, 30), (N/A)
    (5250 - 5350 @ 80), (N/A, 24), (N/A)
    (5470 - 5725 @ 160), (N/A, 24), (N/A)
    (5725 - 5875 @ 80), (N/A, 30), (N/A)

by driver supplied with Linux stock Kernel:
Code:
$ sudo hcxdumptool -i wlp5s0f4u2 --check_driver
initialization of hcxdumptool 6.2.5-29-gf5b28d0...
starting driver test...
driver tests passed...
all required ioctl() system calls are supported by driver

terminating...

Full packet injection and support for all(!) attack modes of hcxdumptool/hcxlabtool series:
Code:
$ sudo hcxdumptool -i wlp5s0f4u2 --check_injection
initialization of hcxdumptool 6.2.5-29-gf5b28d0...
starting antenna test and packet injection test (that can take up to two minutes)...
stage 2 of 2 probing frequency 2484/14 proberesponse 223  
packet injection is working on 2.4GHz!
injection ratio: 17% (BEACON: 1250 PROBERESPONSE: 223)
your injection ratio is poor - improve your equipment and/or get closer to the target
antenna ratio: 82% (NETWORK: 68 PROBERESPONSE: 56)
your antenna ratio is excellent, let's ride!

terminating...

Please notice:
Injection test result is poor, because it was tested using a dummy load (laboratory environment) instead of an antenna. I don't want to jam the entire frequency spectrum for this test.

A good antenna is mandatory:
