I cannot see the release notes for version 20.1.3.2, there's just the old information from ExtremeCloud IQ Virtual Appliance 19.5.1.6.Can you see the new notes?
Short update: the issue is only related to 2.4 radio, as soon as we disable 2.4 on an AP the problem is gone. They are currently still investigating and collecting logs.
The issue is gone since running on 8.2r5. We tried again with 8.4r11 and 10.0r5 but that causes the issue to reappear.We're going to investigate this now with Aerohive, I'll follow up as soon as I have news.
Matthias was the issue resolved with 8.2r5? I'm experiencing exactly the same but with 8.4r4. Affected devices are Samsung Galaxy and IPhones, notebooks work without issues,As advised by Sam I'll test with 8.2r5 now.
