Jacobs Hall Wi-Fi Issues and Maintenance 3/14/16 10PM

by

The wireless networks in Jacobs Hall are currently malfunctioning due to a defect in the new code which was applied on Friday night. This defect has disabled the wireless network by preventing the APs from powering on fully. Staff are currently implementing a hardware based workaround which will bring the APs online for the afternoon.

We have identified a newer version that closes this particular defect, and confirmed with campus IST that it does work as expected. This upgrade will be applied tonight at 10PM and will involve a brief (~2 minute) downtime for the wired and wireless networks in Jacobs Hall.

We will be performing Wi-Fi upgrades at BWRC on Thursday morning to address a critical security vulnerability and also to upgrade the access points. The wireless network will be unavailable during this time and should be fully operational by 8AM.

The new access points will support 802.11ac with 80MHz channels, and will also provide increased coverage and signal performance.

If you have any questions about either of these upgrades, please email networks@eecs.berkeley.edu.

Wireless Maintenance – All Locations, 1/13/16

by

We are recalibrating the system which determines wireless AP transmit power. The procedure requires us to reset the radios several times, which will cause any client machines to disconnect.

We will make the changes separately on each frequency band to attempt to reduce interruptions to the wireless service.
