AX211 6E wireless card as Sniffer in Ubuntu 20.04 or 22.04

PavanSanghvi — Fri, 03 Nov 2023 09:02:49 GMT

Can some one please help me with the driver of AX211 6E WIfi card so that it can be put in monitor mode so that I can sniff the wireless packets in Ubuntu 20.04/ 22.04 OS version.

I am able to put it in monitor mode but it is not capturing any packets

Hello, @PavanSanghvi

Thank you for your reply.

Just to confirm:

Is the Intel® Wi-Fi 6E AX211 the pre-installed wi-fi card in your laptop or is it an integration (upgrade/ not the original card)?
Did you make sure that your Laptop supports this OS with your Laptop manufacturer?
Was it working fine before?

Hello Jocelyn,

I hope you are doing great.

I am experiencing the same issue as the previous user.

The monitor mode does not work for me neither.

I have an HP Elitebook with the Intel(R) Wi-Fi 6E AX211 160MHz, REV=0x370, running an Ubuntu 22.04, and I am not able to sniff ieee80211 packets.

First I verified the monitoring capability is available for this NIC:

>iw list

(output)

...

Supported interface modes:
* IBSS
* managed
* AP
* AP/VLAN
* monitor
* P2P-client
* P2P-GO
* P2P-device

...

Then I configure my NIC to Monitor mode:

> ip link set dev wlp0s20f3 down

> iwconfig wlp0s20f3 mode Monitor

Next verify it is correctly set:

> iwconfig wlp0s20f3
wlp0s20f3 IEEE 802.11 Mode:Monitor
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:o

Then,

> ip link set dev wlp0s20f3 up

I tried:

>iw dev

, but had the same result as the previous user:

I tried to use wireshark and couldn't see any ieee80211 packages or IP/TCP. Nothing. No packets at all.

Best Regards,

Adrian

Hello again Jocelyn,

In the end the monitor mode works. It was just a question of issuing the right commands.

Thanks,

Could you please share how you resolve the problem? if possible could you please provide the right commands for this.
