WirelessNetwork

Wireless Network for employees: eduroam

The wireless network that we advise to use, is eduroam.

Note: the ru-wlan and the science wireless networks are deprecated.

Authentication is done in one of the following ways:

• U-number@ru.nl and RU password (for employees)
• S-number@ru.nl and RU password (for students)
• science-loginname@science.ru.nl and Science-password

How to connect to Eduroam?

Three ways:

1. In your operating system try to connect to the eduroam network. You should be asked for credentials. Use the credentials as written in previous section. Then you should be connected to eduroam.
2. If this fails you can connect to the “eduroam-config” network instead. You can connect to this network without credentials. When you then open a web browser you will be guided to a website where you can download an installation/configuration program. Using this program you are guided in the setup of your eduroam setup. After successful configuration you can connect to the eduroam network.
3. Finally when everything fails you can go to our [System Support department C&CZ] which are happy to help you setting up Eduroam.

Eduroam technical information

• Networkname/SSID: eduroam (be careful: no capital letters)
• Verification/Authentication: WPA2 in combination with IEEE 802.1X (this combination is sometimes also named: WPA2-Enterprise)
• encryption: AES
• Authentication method: PEAP
• Authentication protocol: MS-CHAP-v2
• Credentials; two possibilities, however we advice to use the science credentials :
  • Science credentials:
    • Identity: Science-login@science.ru.nl e.g janj@science.ru.nl (convenient for temporary guest account)
    • Password: Science-password
  • RU credentials:
    • Identity: RU-login@ru.nl (U-, S-, E- of Z-nummer@ru.nl) eg. u123456@ru.nl
    • Password: RU-password

Extra tips in case of problems

• always use the most recent driver for your wireless network card
• give eduroam the highest preference in the list of wireless networks
• in the properties of your wireless network card configure as prefered network
  • frequency: first 5 GHz, then 2,4 GHz
  • protocol: first 802.11a, then 802.11g
• when having a good connection minimalize roaming (switching between wireless access points)
  • prevent roaming by staying a the same place
  • in the properties of your wireless network card configure the agressivity of roaming on minimal
• if you have a bad connection try to move to other location with a better signal strength/quality. If you then find a better connection then often if you move back to your old location this better connection persists.
• in practice the following helps
  • reboot and reconnect
  • remove your edoroam settings and redo the configuration

Wireless Network for guests: ru-guest

First note that guest having access to eduroam on their own university can also that account to access the eduroam network on this university.

Besides eduroam, also the wireless network ru-guest is available for guests (also known as Wireless Guest Accounts or WGA). These guest accounts don't use the 'usual' authentication (802.1X, PEAP/TTLS, MS-CHAP-v2), but use a web page, like in hotels, and therefore it should be much easier to give wireless network to guests.

As employee you can ask C&CZ directly for temporary logins for the ru-guest network. Call 20000 or send an email to postmaster@science.ru.nl .
