Wireshark will not work with wireless

[dpruane]

Capture interfaces show:
eth0 - with IP - shows packets sent and received
wmaster0 - unknown - no packets shown
wlan0 - unknown - no packets shown
bluetooth - unknown - shows packets sent and received
any - unknown - shows packets sent and received
io - with IP - no packets shown.

I can capture packets etc with the eth0 interface but the wireless interface does not appear. I have tried various cards but it does not recognise any of them or the inbuilt wireless adaptor.

How do I get Wireshark to recognise the wireless interface ?

Many thanks

Really? I used to have no problem capturing wireless activity with WireShark... providing I was already connected. I don't have a good working Linux laptop right now, so I can't really see what you're seeing, thus not much help. Sorry.

If you want to just "listen to the wind," kismet works better, then you can still use wireshark to analyse the cap file.

I have been working on ubuntu and wireshark works for me . it detects wireless automatically.

May be this is a reason, as eth0 is connected and packets are transferring through that. There was no active packets transfered via wireless. Try disconnecting eth0 and make connection to be established using wireless. This way you can check, whether wireshark is really not working.

Hi,

I've experienced this before. If you are not connected to a network via the wireless card it doesn't seem to capture packets. If you put the card into promiscuous or monitor mode then you can sniff the packets with wireshark.

depending what you intend to do with the capture, use the aircrack package and turn on monitoring mode using airmon, wireshark will show the interface mon0 and this will give you all packets flying around

Have fun.
