Problem reports are being received regarding an inability to join wireless networks. At first review, this appears to be a separate problem from the recent network stability problems. The UCSB Wireless Web network may be more accessible than UCSB Secure or eduroam

The wireless network appears to have been stable since Monday evening, Sept. 20th, at approximately 6:00pm. The network equipment vendor's engineers have confirmed a new software defect and are conducting further investigation in an attempt to permanently fix the defect. It is possible the wireless network will trigger the bug again, however campus network staff should be able to restore service much more quickly.

"The wireless network is still experiencing problems, including the inability of clients to join wireless networks. The network equipment vendor has assigned two engineers who have successfully worked around these issues at another campus. Network staff are working closely these engineers to restore network stability."

Clients of campus wireless networks, including eduroam, have experienced random instances of service disruption. The root cause is a software defect in the wireless controller infrastructure which was triggered by the increased on-campus population. Similar problems are being experienced at other campuses. The vendor is aware of the issue and working on a solution, however there is no ETA for resolution. Campus network staff are implementing various technical changes in an attempt to restore stability on an interim basis.
