09.09.2026 20:00	02.09.2026 21:00	Wi-Fi Update: Switching the “eduroam” SSID to WPA3-only	Detailsadd
Wi-Fi Update: Switching the “eduroam” SSID to WPA3-only On Wednesday, September 2, 2026, between 8:00 p.m. and 9:00 p.m., the Wi-Fi network with the SSID “eduroam” at ETH Zurich will be upgraded. For security reasons, the older WPA2 encryption will be deactivated. The Wi-Fi network will be upgraded to the current WPA3-only standard. Impact: During the maintenance window, there will be brief interruptions in the eduroam connection at all ETH locations (except for the OCT, which has already been upgraded), causing any ongoing data transfers to be temporarily disconnected. Affected network zones are: ALS, Cx, Etx, HG, LEE, LFx, NW, RZ, H1, H2, H3, HCI, Hix, Ox, BS, and LCA. What you need to know after the migration: Modern devices will generally reconnect automatically to eduroam via WPA3. Older devices that do not support WPA3 will no longer be able to connect to eduroam after the transition. In this case, please switch to the eth[-5] SSIDs. If your device is unable to connect despite supporting WPA3, delete the eduroam profile in your device’s Wi-Fi settings by selecting “Forget this network” and then reconfigure the connection.

Relocation of Core Network Components on Hönggerberg On the weekend of September 5 and 6, 2026, the core network components on Hönggerberg will be relocated to a new room. During this work, the core of the ETH data network will have no redundancies. This affects all services that rely on the data network. During this time, no changes to DNS entries will be possible. Provided there are no disruptions, this will have no impact on users. If everything goes according to plan, full redundancy will be restored by Sunday evening at the latest. Urgent incident reports can be made through the "Alarmzentrale" using the standard procedure. Last change: 21.08.2026 10:36
