2021/04/07 Today, many students received the message "No Internet Connection" when trying to connect to the wireless LAN.
This is a problem caused by the exhaustion of IP address allocation from the DHCP server.
Now that we have implemented countermeasures, connections are gradually becoming available.
We are very sorry for any inconvenience caused.
If you feel that the wireless LAN connection of the laptop computer you brought to the university is not working properly, please check the following 1 to 4.
０．If you can't connect after entering your account and password.
Re-register the SRAS wireless LAN password using the AMI password settings. (Please visit the Information Processing Section.)
１． Power Saving Settings for WiFi Devices
When power saving mode is enabled, the connection becomes unstable.
Especially Intel's WiFi is often in bad shape.
２． Setting up WiFi roaming
The connection will be more stable if the roaming aggressiveness is lowered.
The AP you are connecting to switches frequently.
３．Only one automatic connection.
If you have multiple SSIDs set up on campus, turn off all automatic connections. Or, set only one automatic connection.
If you have multiple SSIDs such as SRAS and eduroam, and automatic connection is enabled, the SSID of the connection destination will change on its own depending on the signal conditions.
４．Intel Drivers
If the driver is old, you can't connect to WiFi6's newer APs, etc.
Today, the SRAS VPN service is very busy.
If you can't connect well, or if you can connect but the speed is slow,
Please try again later.

The digital certificate used for SRAS VPN, SRAS wireless LAN, and authentication server will expire soon.
Therefore, we will switch to a new certificate on the following schedule.
There is no need to change the connection settings, but an authentication screen or confirmation message may appear.
If you see a confirmation message, make sure your fingerprint is correct before connecting.
The new fingerprints are:
54:4b:75:c4:b8:54:1e:0e:5d:0d:8c:94:bb:60:b8:30:3a:61:76:7a
Kakunin no messēji ga hyōji sa reta baai wa, boin (Fingerprint) ga chigatte inai ka o go kakunin no ue, setsuzoku shite kudasai. Kakunin gamen-tō ga hyōji sa rezu, setsuzoku ga dekinai baai wa, otesūdesuga settei o sakujo shi, saido settei o onegai itashimasu.
If a confirmation message is displayed, check that the fingerprint is correct before connecting.
If the confirmation screen is not displayed and connection is not possible, please delete the settings and try again.
