Lucent WaveLAN Problems

We have some problems with our wireless network. We have Lucent WavePointII access points and the orginal 2 MB 802.11 PC cards. Most of the time every thing works fine but for some reason sometimes an access point will stop communicating with the clients. When we use the AP manaager utility to do a a link test, no stations show up. We have to reboot the access point to get communications back.

Has anyone seen this problem? And if so how did you fix it?

TIA,
