802.11 no eapol visible
Hello all,
I wanted to check the eapol traffic when a device is reauthenticated but I can't find any eapol traffic at all. I use Kali and the TP-Link WLAN-Adapter TL-WN722N. After setting up the Wifi adapter I was able switch the adapter to monitor mode. Anyhow, while I was able to see the Monitor-Mode-Checkbox within wireshark by yesterday, I can't see it anymore, there is no checkbox at all. I fear that my recent updates were causing the internal card to interfere somehow? What are possible ways to see and set the checkbox again?
So generally I did the following steps before starting wireshark:
sudo ifconfig wlan0 down
sudo airmon-ng check kil l sudo iwconfig wlan0 mode monitor
sudo iwconfig wlan0 channel 11
sudo ifconfig wlan0 up
Once wireshark was running, I switched on the Smartphone so it will do the eapol. Anyhow the filter eapol did not trace anything within wireshark.
when I checked "iwlist wlan0 channel" I was able to see that channels are supported for 2,4 ghz and channel 11 should be the right one to choose? All outputs are shown at the end of the message. Now I'm a little bit confused, as I could see in my router settings that my smartphone seems to use 5 ghz but when checking wlan0 channels I can only see the frequencies for 2,4 ghz? Last but not least it would be interesting if I have to start wireshark out of the command line with some additional parameters or if it should work by simply opening and starting wireshark on wlan0?
Thanks a lot for every hint and advise in advance.
