I've been having a problem with the wireless access point (1240AG) randomly dropping and then picking back up clients. It is causing problems because we are in the middle of inputing orders and sometimes lose what we are doing because of this. The stations are not set to expire and as of right now I'm not using wireless security. The only other device in range that is a variable is that I'm using a Linksys range expander and a far point in the warehouse. Otherwise it's just the Cisco unit. Below is the message I'm getting in the logs. Thanks.
