Wireless FAQ's

How do I reconfigure wireless on my Mac after a password change?


The Mac OS X keychain is a feature that is meant to simplify use of your computer by reducing the number of passwords you have to keep track of. Unfortunately, when you change or reset your Butler password the Butler keychains are not updated. Because of this, you may not be able to access the network or Apple Mail/Entourage accounts until they are updated. This can be fixed by changing the saved passwords in Keychains.

  1. In the top right of your screen, click the Magnifying Glass. Type Keychain into the search bar. Select Keychains or Keychain Access from the dropdown menu
  2. If you use the Butler wireless, select the BU Secure Wireless keychain from the list
  3. If you are changing your Apple Mail or Entourage password, (if using IMAP) select the internet password with your username in parentheses, (if using Exchange) select the Exchange password
  4. Under the "Attributes" tab, check the box next to Show password. You may be prompted for your local administrator password. Then, change the previous password to your new password. Click Save Changes and close Keychains

Can I use wireless on campus if I don't have a Butler username or password?

Guest/open wireless access is available in select areas. The guest/open wireless network is not encrypted and only permits connecting to the Internet. Certain Butler services are not available on guest wireless.  See our coverage areas for more information.

Can I install a wireless network or access point in my room or office?

No. Personal wireless access points and routers are not allowed anywhere on the Butler Network including residence halls, Greek houses or any other buildings connected to Butler's network. Personal wireless access points interfere with the operation of the network and are in direct violation of Butler's computer use policy. Individuals installing or using personal wireless access points are subject to losing part or all of their network privileges. Read more about IT's Wireless Access Standards.

Does the Butler wireless network support my iPhone/Windows Mobile device?

Yes. You must have the latest software installed to ensure your mobile device will work correctly. Visit Get Connected for connection instructions.

What kind of wireless card should I buy?

IT recommends the use of a/b/g/n wireless cards, which decrease interference, especially in residence halls, the Village, and Greek houses.

What can interfere with my wireless signal?

Wireless signal problems may result from other devices using the same radio frequency as the wireless network. Butler's wireless network uses both 2.4 GHz and 5.8 GHz bands for G and A radio signals. Other "wireless" devices exist in the marketplace that also use the 2.4 GHz frequency band and can cause interference to users of the wireless LAN service. These devices include, but are not limited to, other 802.11 wireless LAN devices, cordless telephones, cameras, audio speakers, wireless printers, and microwaves.

Does a wireless connection use a lot of power on my laptop?

YES! A laptop's batteries will deplete faster when using wireless since the battery must power the wireless card while connected.

Which operating systems are currently supported?

The only operating systems that are able to support this level of security are:

  • Windows 7
  • Windows 8
  • Windows 10
  • Mac OS 10.9 and higher
  • iOS
  • Android
