Wireless Networking

We will be performing various network maintenance activities throughout the day on Wednesday, March 26th during the previously announced Soda Hall 2nd floor power shutdown. We expect that most of our work will not affect wired and wi-fi network service, however there will be some brief outages as described below.

Between 12PM and 1PM on the 26th, the areas listed below will experience at least one interruption to network connectivity. We expect most of these interruptions to be under one minute in length, but some wi-fi service may be unavailable for 5-10 minutes.

• BWRC (wired and wi-fi)
• BiD in HMMB (EECS wired)
• Soda Hall all floors (wi-fi)
• Soda Hall 4F north side, 5F-7F (wired and wi-fi)

Update 15:44: This work has been completed and all networks are online. Please contact us at help@eecs.berkeley.edu if you notice any issues.

Cory Hall networks were unstable today between approx. 9:25AM – 11:00AM due to an apparent misbehaving end-user device on the 4th floor. We have temporarily removed this device from the network and all networks are stable at this time.

Please contact us at help@eecs.berkeley.edu if you notice any issues or have any questions.

We have been experiencing campus-level network instability since sometime around midnight, which is affecting the EECS and BWRC networks. Network team is investigating and working with the vendor to restore full network connectivity.

Update 2/11 6:41AM: The campus network team resolved these issues late Friday evening and our monitoring indicates that the network has been stable since. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.

On Thursday, November 14th, between 6:30 and 9:45 AM, Cory Hall third floor wired and wireless networks will be offline due to electrical work being performed at the main service panel. Facilities is performing this work in order to restore electrical power to the Cory Hall Helpdesk.

Facilities is reporting that the west side of the third floor (which includes the network closet) will be without power from 6:30 – 9:30 AM. The network devices, particularly the wi-fi APs, will need some time to boot up after power is restored. We typically expect network connectivity to be restored within 10-20 minutes after power returns to the network closet.

Update 11/14 9:36AM: This work was apparently completed without any interruption to the network. Please contact help@eecs.berkeley.edu if you have any questions.

At 10PM on Thursday, July 18th, we will be performing firmware upgrades on various BWRC network devices in order to address a bug in the current version.

All wired and wireless networks at BWRC will be offline for approximately 5-15 minutes during the upgrade.

Update 7/18 22:12: The upgrades have been completed and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.

At 10PM on Wednesday, July 17th, we will be performing firmware upgrades on various Soda Hall network devices in order to address a bug in the current version.

All wired and wireless networks in Soda Hall, except for those on the first and second floors and in machine room 340, will be offline for approximately 5-15 minutes during the upgrade.

Update 7/17 22:12: This work is complete and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.

Due to planned electrical work, all Cory Hall third floor wired and wireless networks will be offline during the morning on Tuesday, June 25th. Per facilities, power (and therefore network) will be unavailable between 7:30am and 12:30pm. The network, particularly wi-fi, may take as long as 15 minutes to fully come online after power is restored.

Please contact us at help@eecs.berkeley.edu if you have any questions.
