You can use wireless network service all over the in-house area in JAIST include research buildings, lecture buildings, library, commons, and Tokyo Satellite. And you also can use Wi-Fi connectivity in "eduroam (education roaming)" partner campuses.
Supporting Wi-Fi standard
- 2.4GHz band : 802.11g / 802.11n
We don't support 802.11b because it's slow connection, but consume high bandwidth. If you need to connect 802.11b only device to Wi-Fi for your research, please contact us.
- 5 GHz band : 802.11a / 802.11n / 802.11ac
Settings for Wi-Fi connection in JAIST
You need a "digital certificate" first, to connect your PCs to JAIST Wi-Fi service.
1. (If you want,) Apply the request for changing E-mail address.
2. Get your digital certificate
3. And set-up your PCs to connect to Wi-Fi network
Followings are the basic setting information:
- SSID : JAIST or eduroam
- Security type : WPA2 - Enterprize
- Encryption type : AES
- Authentication Method : EAP-TLS
- User ID : [Your JAIST account]@jaist.ac.jp
- Ex. If you are student, use sXXXXXXX@jaist.ac.jp style instead of changed E-mail address.
Please check following links to get step-by-step instructions on each operating systems.
Notice for wi-fi network access
Notice that, the digital certificate become invalid if you change your E-mail address because the certificate contain E-mail address as a key. So you should apply request for changing E-mail address before downloading your digital certificate.
For some kinds of machines which can't connect to the above JAIST Wi-Fi Service via digital certificate, or for users who can't get their digital certificate (Guest Users etc..) , non - authenticated network is available.
What is Eduroam?
The eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community. Having started in Europe, the eduroam has gained momentum throughout the research and education community and is now available in 71 territories (As of Mar 2015).
JAIST is a eduroam partner. So you can get Wi-Fi connectivity in partner's campuses by using JAIST account.
The setting of your PC to connect to Wi-Fi is same as JAIST Wi-Fi. However, the SSID depends on each site/partner, "eduroam'' is widely used but not all. Please get information for each site from web page or Wi-Fi administrators in each site.
It is difficult to get your digital certificate which you need to set-up your PC to connect to Wi-Fi. Please set-up and verify the setting in JAIST prior to the departure.
And please note that some partner restrict services for eduroam users (ex. eduroam users can use only VPN access to parent organization).
Pocket Wi-Fi and wireless access points
Pocket Wi-Fi use and other on campus private access point causes deterioration of wireless environment due to interference, please refrain from using it as much as possible and use wireless LAN service provided by Information Infrastructure Research Center instead.
However, in cases where there is a necessity for research, or in case the electromagnetic wave condition in your room is extremely bad or difficult to receive the center provided service, you can install and use it. In that case, we strongly urge you to set the following settings in order to reduce interference to other users.
- Set the radio output as low as possible (minimum setting just enough for your dormitory etc).
※ It is not the case at all that the stronger the electric wave output is, the better the electric wave environment is. On the contrary, if the electric wave output is high, the interference increases and the quality worsens.
- When using of 802.11b / g / n (2.4 GHz band), choose channel 1.
Especially, at the student dormitory, though wireless LAN service is being implemented at the center, severe interference has occurred due to the influence of many access points placed in each room, and the situation is of very low quality. The deterioration of quality leads to the emergence of new access points with high radio wave output, and the interference is further increased, and everyone is in a vicious circle unsatisfied. Please cooperate for better management environment.
