Three wireless networks are available:

This network is the preferred choice for all JHU affiliates (Faculty, Students, Staff) and has the following advantages:

  • High speed data
  • Access to licensed resources

This network is for guests and visitors at any Hopkins Campus and is intended for casual use.


Eduroam is a service that allows students visiting participating universities to access their home library's databases.  JHU is a member of Eduroam.

Per their website: When a user tries to log on to the wireless network of a visited eduroam-enabled institution, the user's authentication request is sent to the user's home institution. This is done via a hierarchical system of RADIUS servers. The user's home institution verifies the user's credentials and sends to the visited institution (via the RADIUS servers) the result of such a verification.


  1. Ask the patron to be sure that all instructions were followed (i.e., laptop configuration, location, etc.)
  2. The patron has to make sure that their laptop is updated with the latest wireless drivers (they need to check their computer company's website for the latest drivers). This step will most likely resolve the problem with the wireless connection.
  3. IT Support Services or End User Support (down at A-Level, Ext. 6-0870) can assist. If no one is available,  contact IT@JH (Ext. 6-4357).


Ethernet cords are available at the Service Desk. Ethernet ports are located in group study rooms in MSEL. Other ports throughout the library are marked with a black icon. A cord costs $1.50 and can be rung up as a fine.

In most instances, the patron is not using a jack with a black label over it. These are the only jacks that are configured for wired access.

First-time users should simply follow configuration instructions for their desired network (see "Wireless" tab).
