Wireless Networking

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.

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.
