Coahoma ISD provides WiFi access to all members of Coahoma ISD and approved guests. All traffic is monitored and recorded. App usage is also tracked. Usage requires that a security certificate is installed on your device - the certificate is located at the bottom of this page. Please download and install both certificates on your device.

If you do not have this certificate installed, when using Coahoma ISD's WiFi, you may not be able to access certain websites.

If you are a student or staff and you are experiencing problems on your provided device, please contact your Technology Coordinator.
