atheros client connection problem

[Patrick Chia]

sometimes when i try to connect to my wireless network using the atheros utility for the nc4000, i will not able to connect to the internet or even ping my router, even though the atheros client shows excellent signal connection and ip address is received from dhcp. sometimes i need to restart my notebook for the wireless to work, but not always.

i've tried to use another connection utilty, odyssey client, from funk software to connect, and no such issues occured. however, as the odyssey client is only a demo, and the atheros is the native utility, is there a way to resolve this connectivity issue?
