Yah i guess i was more wondering if i needed a patched firmware instead of the one i'm using out of the box in Kali.

I've attached a copy of the dmesg output. I dont see any entries of concern related to broadcom adapter. It seems to detect it properly and load the drivers without issue.

Looking like i'll just have to bite the bullet and buy a diff adapter. Any recommendations on a good wireless usb adapter? I was thinking maybe TP-Link TP-WN722N.

If the firmware is missing, it's unlikely you would have been able to use the card.

In any case, have you checked in dmesg?

One thing i'm unclear on is in relation to the installed firmware for my BCM4331. I just ran a typical install of the latest Kali image. During the install i did get a message telling me i'd need to download some files for b43 firmware, but based on what i'd read online, i decided to skip that and leave for when Kali was installed. Once Kali came up, the wireless just seemed to work out of the box so i assumed things were fine. When i say it worked, i mean i was able to see the APs in range.

There are posts online that talk about needing to download a patched copy of the proprietary drivers from Broadcom. I've also read that these are built into Kali linux. Can someone confirm if things should indeed work out of the box, or if i need to do some manual install of patched drivers?

Thanks :)

I've verified that there are definitely clients connected on 2.4 ghz to the AP that i'm monitoring. From what i understand, the BCM4331 wifi adapter supports both 2.4ghz and 5ghz anyway, so it seems like it should be picking up all of my clients.

No idea why that happens. As for any unusual behavior, check in dmesg for any error messages.

Broadcom in general is crappy (often nicknamed Broadcrap), so a different card is recommended.

Are you that all your clients aren't connecting to the 5GHz instead of the BSSID that you selected (check the BSSID the different devices are connected to)? 802.11ac is 5GHz only.

Hi folks,

Yesterday, i setup Kali for the first time, with the intention of using an older Mac Mini to try out fern wifi cracker. The install went well, and soon after booting up, i opened up fern wifi cracker. It detected my wifi interface (Broadcom BMC4331) and put it in monitor mode. Then i clicked to Initialize it, which found a number of WPA access points. I opened up the Attack Panel and it started waiting for a handshake on my own wifi network. After a while nothing happened, so i tried disconnecting/reconnecting some devices but still i didn't see any evidence of a handshake being captured.

I decided to run the underlying command line tools that fern uses manually. My plan was maybe i could get a list of clients and attempt to deauth one of them to force a handshake. I was able to get a list of the access points using `airodump-ng wlan0mon`. Then when i tried to run `airodump-ng --bssid <BSSID_OF_AP> -c <CHANNEL_OF_AP> <WIFI_INTERFACE` against my access point, i never saw any stations populate. I made sure to stop network services in the hopes that would get things working but no luck.

I know this seems to be a common thing that is asked. Some have suggested that the wifi interface being used may not support wireless n/ac, and so it wont capture any clients connected in that mode. Mine does at least support wifi-n though. It just seems strange that i wouldn't see any clients listed at all. Other posts have had no replies. I'm at a point where i'm not really sure what to try next. Can anyone give me any guidance? Should BCM 4331 be working fine? Should i look at buying a different wifi adapter?

Thanks very much. Appreciate the help. Really hope i can get this working. :)

because I had a lot of Qualcomm Atheros Wireless Cards and the firmware came in the kernel or in the firmware-linux metapackage with the non-free repo. Had you tried to apt update and install the firmware-linux?

Ce serait plutôt:

wpa2scan [PARAMETERS] | aircrack-ng capture-01.cap

-n est pour du WEP et il n'y a pas d'option -O. Aussi, sudo n'est pas nécessaire

-n est pour numeros et option -O c'est de longeur de characteres autre
