The blocking of Flash content by Adobe means that certain management interfaces of Extreme Networks products have been used since 12. January 2021 are no longer available. Components with the so-called WiNG GUI are affected, for example wireless access points and wireless LAN controllers.

Initially, the manufacturer found a change in the client system time as a suggestion for a workaround, which, however, would have far-reaching side effects. This notice has since disappeared. Extreme Networks now refers to access via command line (SSH or console) for configuration and to the “Extreme Cloud IQ Free Connect level” for monitoring. A new release for the WiNG Manager is expected to be available in the coming days.

What will take a long time … – or not It is unclear why the manufacturer ignored the end of support for Flash. Already in November 2019 he announced that they were working on a solution for the time after the end of Flash. For its switches of the ExtremeXOS series, Extreme announced in July 2020 that from version 16. 12 + no more flash to Application coming.

On 31. December 2020 Adobe officially discontinued support for the Flash Player after years of notice. In addition, the manufacturer, headquartered in San Jose, USA, has been blocking since 12. January 2021 the execution of Flash-based content.

Extreme Networks has announced in its user forum for this Wednesday, 12 PM EST (16 PM CET), an update for the Windows-based application WiNG-Man 1.0.4 announced to enable management before an HTML5 GUI is available. The same forum shows that some users are currently experimenting with workarounds such as replacing dll files with ones from old versions (not recommended for security reasons) and changing the flash configuration file mms.cfg, which both seem to work.
