Soda Aggregation Router Upgrade, 5/2/17
We will be performing a software upgrade of the Soda Hall aggregation router at 6:30 AM on Tuesday, May 2nd. Wired and wireless networks in Soda Hall will be unavailable for 5-10 minutes while the router reboots. BWRC will also be cut off from the outside world during this time as its uplink is dependent on this router.
The Millennium research network will not be affected.
This upgrade is being performed to resolve certain bugs in the current software version so that we can move forward with our early-stage IPV6 deployment, which is currently targeted for this summer.

Wireless Controller Upgrade, Jan. 26 2017
We will be performing an emergency upgrade of our wireless controllers tonight beginning at 9:30PM to address a bug which has been causing periodic controller crashes that bring down the wireless network. The last outage generated by this bug was on Jan. 18, but we also experience more frequent crashes that do not affect production due to redundancy.
The controllers have the capability for a hitless upgrade (upgrade without affecting service), however we have had mixed experience with this feature in the past. We expect there may be an outage of 10-15 minutes while the controllers reload after the upgrade.
This maintenance will affect wireless networks in Soda, Cory, Sutardja Dai, Blum, and Jacobs Halls, as well as the Calvin Lab, BWRC, and BiD Lab in HMMB.
Please direct any questions about the upgrade to help@eecs.berkeley.edu.

Brief Wireless Network outage
The controllers recovered and APs automatically rejoined; all APs should be back online now.
We are investigating the cause of the crash and any possible steps we can take to prevent this from occurring again.

Changes to EECS-Secure, Thurs Jan. 12th
Overnight between Wed. 1/11 and Thurs. 1/12 we will be transitioning EECS-Secure to a new authentication backend. The old servers, etips1.eecs.berkeley.edu and nps-0.eecs.berkeley.edu will be retired and replaced with a new cluster which will identify itself as clearpass.eecs.berkeley.edu. There will be no interruption to wireless connectivity during the transition.
EECS-Secure will continue to function as it has, but your computer may notice the change in server certificates and prompt you about it. We are listing some steps below that may be helpful if you have trouble connecting on Thursday morning, and remember that you will be able to use other networks (e.g. AirBears2, CalVisitor) to visit this page and the EECS-Secure FAQ.
Windows 10:
* “Continue connecting? If you expect to find EECS-Secure in this location, go ahead and connect.”
* You can click “Connect”, but first we recommend clicking “Show certificate details” and verifying the thumbprint against the Server Certificate at the EECS-Secure FAQ link below.
Mac OS:
* “Before authenticating to the server ‘clearpass.eecs.berkeley.edu’, you should examine the server’s certificate to ensure that it is appropriate for this network.”
* Verify that the server name is “clearpass.eecs.berkeley.edu” and click “Show Certificate” to confirm that the certificate is valid; then click “Continue” to connect.
Linux:
* We have seen many different behaviors depending on distro and version. If you have trouble, we recommend deleting the saved network and reconnecting, making sure to check the authentication details in the EECS-Secure FAQ, which is linked below.
If the above aren’t helpful to you, you might try following the Linux advice by deleting your saved EECS-Secure and reconnecting from scratch. In any case, if you have trouble, please visit the helpdesk in 395 Cory Hall.
More information about EECS-Secure authentication, including configuration details, certificates, and certificate fingerprints can be found on the EECS-Secure FAQ:
https://iris.eecs.berkeley.edu/15-faq/21-network/eecs-secure.html
This change ONLY applies to EECS-Secure and will not affect any other networks, such as EECS-PSK, AirBears2, etc.
If you have been using EECS-RADtest to help us test the new servers, that network is no longer available and we strongly recommend you remove the saved network from your machine.
As a reminder, mobile devices are not fully supported on EECS-Secure. Depending on device and OS version, you may be able to connect, but we can provide only limited support. If you can’t connect to EECS-Secure, we recommend using CalVisitor, or EECS-PSK if you require EECS network access.
If you have any questions or problems, you may visit the helpdesk at 395 Cory Hall or help@eecs.berkeley.edu.
