@sgnb Running it in a VM on my server. But can close off the controller and the speeds are still bad so I know its unrelated to the actual controller.

I did change out my ethernet cable and so far it has not happend in about a month though ever since doing that.

Still trying to track this one down. Questions for others who are having these issues:

How many wifi networks do you have configured within the eap devices? More than 2 on the 2.4GHz band?

Do you have any high-bandwidth always-on devices on the network i.e. high-definition survaillance cameras?

@sgnb 

Only 1 2.4Ghz guest network and 1 5Ghz network.

High traffic yes

@HPad but in your case it seems like it was a cabling issue? after you tried a different ethernet cable the problem went away?

I am having the same problem. I have only one AP that runs in standalone mode, without any controller. Speed drops after few hours without any explanations. Reboot fixes that but in a hour or two it goes back to slow speed again... Getting feeling that EAP245 firmware is buggy or it has some sort of overheating issue. I am happy that bought only one and not 3.

@AlexS20 do you have any wifi security cameras? like the wyze cam?

@sgnb 

Yes, 1 Wyze v1 and one Wyze v2. Do you think it is because of that?

@AlexS20 do you use the RTSP firmware with it or fanghacks firmware on the wyze cameras?

I think there's something within the TPLink firware that doesn't like always-on wifi security cameras. Maybe it's the high bitrate, I don't know

I ended up using a separate wifi router just for my wifi security cameras, an old device that my ISP gave me. It's sad really, that a cheap ISP-provided residential router works better than these expensive TPLink routers (which are advertised as "enterprise grade")

@sgnb 

I see, ok, going to try to turnoff all cams for a few days and see if it changes anything

Thanks for the hint

@AlexS20 Try that and then come back to let us know. Maybe if enough of us gather evidence of the problem then TPLink will investigate it
