been trying to get wireshark running on my laptop but having trouble getting it to capture on my wireless card. its a cisco aironet cb21ag-e-k9 card. it shows up ok in the interfaces but when you select it it does not capture packets. i have managed to get it working once so i know it does work but since then have not had any success. i have re-installed winPcap and wireshark the card does work ok so the driver are working, not sure what to try next?
