Upon the request of our client in Salt Lake City, UT, USA, a post-wireless site survey was conducted to address reported intermittent connect/disconnect and wireless coverage issues. The site was equipped with Cisco/2802i APs with internal antennas. During the survey, the RF Engineer identified wireless signal gaps and numerous Rogue Devices outside of the client's control. Detailed reports on individual AP issues were provided, including a remediation strategy. Power level issues with certain APs were also pinpointed, leading to a recommendation for RF profile optimization through the Meraki Dashboard.
