EAP 670 degraded speed at 100Mbps

Hi,
We are experiencing the same issue with downgraded speeds AP TP-EAP 670. When we installed the device a year ago, we achieved over 600 Mbps on new computers. However, we recently noticed a speed reduction to 92 Mbps while connected to a TP-Link JetStream Managed Switch (TLSG3452P) with PoE+.
Initially, we suspected a firmware-related issue and upgraded from version 1.0 to 1.1.0, but the problem persists. The switch still shows a 1000 Mbps negotiation.
Any insights or recommendations would be appreciated.
Thank you,
Feras

Hi @IT_Team_HT
Even though it's showing a 1000M negotiation on the switch, this is mostly because the EAP was negotiated to 100M.
And this is normally caused by the Ethernet cable you are using.
Please change the cable you are using.ng, and see if the issue persists.

Trying to run WiFi Optmization to confirm a clear channel?
Confirm the clients have decent signal? enable signal column in the client list and check. Anything above -73 is the start of low signal.

Hi @IT_Team_HT,
Try to confirm that the issue related to the wifi or wired network segment by testing each segment independently. You can run iperf on the EAP670 and test from wireless and wired clients. Refer to this article for running iperf on the EAP: https://www.tp-link.com/us/support/faq/3105/ (If you use the Omada Controller, you can use the Network Tools->Terminal there instead of ssh).
