I've been on 1.0.14 for a few months, and I have not noticed anymore of those weird drops. I also got rid of one of the devices that was dropping so who knows if it's fixed...

  @zinge Support gave me EAP650v1_1.0.91_[20240814-rel53153] which was ok. The issue occured after about 3 weeks again, but otherwise it was running stable. I recently tested 1.1.0 but that was the worst. Connection dropped every 6-16 hours.

Before moving to TP-Link, I had a Synology WRX560 for a week to test, which interestingly had exactly the same issues, but with all devices, not just 2.4GHz. It was even worse, connections were dropping at least once an hour. Many people had this issue on the Synology forums, but there has never been a solution to it, so I returned it. Maybe this whole issue is a buggy driver/chipset issue, the Synology device had some Realtek chipset for WiFi, but Idk what's inside the TP-Link EAPs. I also have a EAP115 which never had any issues. Maybe I'm adding a more recent BE9300 some time in the future.
