How is the speed measured? When testing the speed, perhaps different approaches will yield different results. I recommend using iperf to measure the speed. To test the speed, follow these guidelines:https://www.tp-link.com/support/faq/3105/

Furthermore, which band do you relate to?2.4G or 5G? Do you also try testing the speed on a different device?Take note of the client's link speed when you test the speed. Here's the link to check the wireless client's link speed:https://www.tp-link.com/support/faq/2265/

Furthermore, have you configured the SSID with any additional settings? The network can be optimized by using WLAN optimization.

Thank you very much for your help Hank21!
 

I have carried out the measurement with different devices (Thinkpad, Pixel7pro, etc.) on different EAP650s. Direct proximity 5Ghz.

 

Here I used f.e. the app speedtest (speedtest.net) to measure the internet speed.

I also copied files to and from the Synology NAS connected with 2.5GB. In both cases, the possible capacity of the connection was not utilised.

 

The fibre optic connection has 1000Mbit down and 250 MBit up (verified via LAN) The upload speed is reached and the download speed is 200 MBit. The same applies to copying files to and from the NAS. There the upload speed is 70-80 and the download speed is 50.

 

The WLan optimisation is on and only works with an AP (EAP 653) that works as a repeater. Except for one outdoor AP, the others are connected via LAN and then a yellow exclamation mark appears next to the model with the message "the AP in the mesh network does not support AI Wlan optimisation".

 

I have also deactivated IDS/IPS Intrusion Detection/Prevention. Then I swapped the switch for the former Netgear - nothing worked.

 

I will swap all the patch cables again today. I have already rebooted the devices.

 

I have also integrated a raspberry as a DNS filter (homeassistant, AdGuard) as a DNS server. I disconnected it and it has nothing to do with the internet speed - it didn't help.

Hi @Liftboy 

Have you checked the link speed when connect to the EAP SSID? Please also go to controller > Devices > select EAP to check Uplink, what is the Negotiated Speed here?

Please help to test the speed between the EAP and the wireless client, what is the result? 

There are many factors that can affect wireless network speed. We would appreciate your assistance in checking if there are any other potential factors in the network that could be impacting the wireless network speed. Please let us know the results of your tests.
