Unstable Wifi Connections - AP305C and AP4020

Firmware: 10.8.5.6 (Including numerous other ones prior)

I know there are a lot of various settings and configs, so not sure exactly what to post here first so I'll describe the issue first.

This issue affects multiple locations utilizing Extreme AP's and Switches. (5 total locations at the moment)
1. Client's workstation disconnects from Wifi and they need to manually reconnect
or
2. Client's workstation is connected to Wifi but randomly every so often the Wifi icon in Windows says "No Internet" for a few seconds, then automatically resolves itself.

It's an issue that has been spanning several months, multiple tickets, various changes on configuration including power settings, various firmwares, and moving physical access points. So far no success.

The issue is intermittent, occurs randomly, a user can experience it once per day or multiple times a day. Every single day we get reports from users especially when it knocks them off their zoom and teams calls.

We have several users hardwired in with cable, and they never experience the issue.

Prior to implementing Extreme in these locations, they were all running on Unifi AP's, Unifi Controller for almost 10 years with 0 issues. The locations that are still on Unifi have 0 issues. But all the locations with Extreme all experience these disconnect issues.

The locations are all within the city so the surrounding SSID's from neighbors is dense, but it never caused any issues with Unifi on much older technology.

Reaching out in case there are any common gotchas that need to be looked into or configured when implementing Extreme APs.

One location has about 6 AP's covering 3 floors the other locations have less AP's. Overall network setup is pretty simple. 1 SSID covers employee network, 1 SSID covers guest network, both on a different vlan.

thank you in advance for any replies.
