Cause
Devices on TTUnet Wi-Fi and TTUguest Wi-Fi get 10.x.x.x IPÂ addresses. When using 10.x.x.x IP addresses, wireless clients cannot host services and be accessed remotely from the wired network or from certain portions of the Wi-Fi network. In other words, wireless clients can access services on other clients/servers but cannot host services themselves (for example, laptop on Wi-Fi can't share files with a desktop on the wired network).
Resolution
There is no known resolution at this time. The services are functioning as intended.
Workaround
It might be possible in some cases to connect to one wireless device from another wireless device (when services are purposely hosted, of course). However, this is not supported or guaranteed to function.
