Wireless Access Tools

  1. Guest Reg: Create a temporary guest user (similar to the old conference system).
  2. My Devices: See the devices you have registered on the wireless network and be able to extend the expiration date or manually retire them.


Web mail is fully supported. Non BNL email clients that talk directly to mail servers will only be able to receive email and not be able to send email via the SMTP port (25). Currently there are no SMTP relay servers provisioned for the visitor network at this time.

Please ask your home institution about web email access or authenticated SMTP to port 587.

Wireless Printing

Printing is available using a mechanism called CUPS (Common Unix Printing System). CUPS will allow wireless users the ability to print directly to network printers. CUPS provides backward compatible lp/lpr programs.

Laptops or other computers connected to the Visitor Networks at Brookhaven National Laboratory do not have access to the same printers as those connected to the internal network. The procedures for adding a printer while connected to the Visitor Network are the same as for the internal network. The host names are all the same as well. The difference is that on the Visitor Network does not have the same selection of printers as on the internal network.

Please contact the Help Desk for help for setting up your printer on the visitor network.
