If laptop clients are doing the same then not 7920 specific. Sounds like you have a session timeout configured in the autonomous AP.

Hi ,

Try do enable long preamle, this can help you.

see this FAQ:

PS. If the PC are IBM (a bit older pcs) the wireles NIC have had som problems , the preamble will fix this too..
