Wireless Access Points / Routers

  1. Turn off any personal routers. The use of personal wireless Access Points or routers is prohibited in residence.

These devices cause interference and prevent others from using Acadia's wireless network correctly.

Cellphone Hotspots

Turn off any personal cell phone hotspots and the experience on Acadia's wireless will improve for everyone, and you will save on your data plan. These device cause interference and prevent other users from using Acadia's wireless network correctly. 

Apple Time Capsule

  1. Please turn off wireless on these devices
  2. Connect your Apple Time Capsule on the wired network to back up your devices.

Apple Time Capsules can fill the entire wireless bandwidth in their area and make other use of Acadia's wireless difficult.

Gaming systems 

All systems:

  1. Connect your gaming system on the wired network.

All modern gaming system have the ability to connect on the wireless, however wireless increases congestion and decreases speed and performance. 

Playstation 4 (PS4)

  1. The PS4 sets itself up as an ad-hoc wireless access point with its own network if you have Remote Play turned on and the option to connect directly to a PS Vita. If both the PS4 and Vita are one the same WiFi network, you can turn off the direct-connect option and the ad-hoc wireless broadcast disappears.

Streaming devices (Chromecast / Roku)

The Chromecast only broadcasts its wireless network for initial setup. Should the Chromecast fail to connect to Acadia's wireless network it will automatically go back into its setup state and you will see the ad-hoc wireless network become available. A blinking white light means the Chromecast is not connected to a wireless network. A solid white light means that the device is connected to a wireless network and ready to accept 'casts'. A blinking Chromecast should either be setup or disconnected from your TV or display device.

Some models of Roku streaming devices are known to setup an adhoc wireless network to allow their remote control to communicate with the device.  This wireless remote network causes interference with other wireless networks that may be running on the same channel, and can degrade performance on the Acadia Wifi network.
