I need some help with an issue i'm having in a production environment. This wireless network consists of about 25 1242AG ap's, with a 4402 WLC . Currently there is anywhere from 10-40 clients on the wireless network. There is an ssid for mobile equipment (tow motors), the security on this ssid is security: WAP+WPA2, static 104 WEP Key, WPA Parameters: WPA encryption-tkip, WPA2 encryption-aes, psk format-ascii.
The problem we are having is these mobile clients are currently loosing their connection in very sporadic areas of the building, and its been hard to re-produce this and figure out the cause. I'm trying to go over the logs and see what could be the cause of these clients not keeping their connection (roaming, authentication, coverage problems?) but could use some guidance. Below are a few errors I picked out off the controllers logs.
Any guidance would be greatly
Decrypt errors occurred for client *.*.*.* using WPA key on 802.11b/g interface of AP *.*.*.*
Coverage Hole Detected for AP b02wst517 whose Base Radio MAC is *.*.*.*. Number of Failing Clients 1
