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:

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:
