distro: Ubuntu 6.06.1 LTS
kernel: 2.6.15-26-386
card chipset: Hermes1
firmware: 8.72
driver: 0.15rc4 (0.15 will NOT compile)
aircrack-ng: 0.9 (1.0 will NOT compile)

the problem: airodump-ng stops capturing after about 18 to 20 beacons.... driving me nuts trying to figure out why
have done everything: removed Network Manager, removed wpasupplicant, ect

if anyone can point me in a direction to the solution, i will be very grateful ...
thx
