Thank you for your help.
In response to Steve I have used tcpdump -i en1 and it worked fine. The connection did not drop.
As for wireshark as soon as I hit capture options the connection drops even if I just type in en1.
After further testing I have found that the connection drops but if I start the capture and leaving it running I can then reconnect to the wireless network and it will start capturing the packets.
Thanks again for the help

Try not using "List available capture interfaces" - capture on en0 for
wired captures and en1 for wireless captures. Also, don't use the
drop-down list to select an interface in the capture options window -
just type en0 or en1. That might help.
This is a known problem - or, rather, a consequence of several known
problems. Some can be fixed in libpcap (I'll look at that), some in
Wireshark (I'll look at that - but those would also need the libpcap
fix, meaning Apple would have to pick that fix up for the system libpcap
or you'd have to somehow get a version of Wireshark built with a fixed
version), and some in the driver for the wireless adapter (somebody in
the group at Apple that does AirPort adapter software would have to look
at that).
