Slow throughput after vlan assignment by NPS
hello, I have a GS1920 switch and a NW220AX wifi terminal. Without dynamic VLAN assignment. the flow is ok. As soon as we attribute a vlan dynamically we find ourselves with a flow rate of 100 mbps. Impossible to know if it's the hardware or the configuration. Can you help me?

Hi @Ulthane
I'm pleased to inform you that the throughput drop issue following dynamic VLAN configuration has been resolved with the latest firmware update (V7.00(ACCO.1)C0) for our NWA220AX-6E model. For more information on this firmware release, please refer to our latest post:

Hi @Ulthane
To better understand your situation, could you please provide the following information?
- Is the 100 Mbps flow rate the throughput between the AP and the WiFi client, or is it the link speed between the AP and the switch?
- Could you try connecting a PC to the switch and running the dynamic VLAN assignment, then check the flow rate?

Good morning,
If I connect a PC to the switch via Ethernet, I easily obtain 600mbps or more. This only happens in WiFi, and only if I set the dynamic VLAN assignment from a Radius server (NPS).I tested a lot of settings on the access points but nothing worked.

Hi @Ulthane
Thanks for sharing the additional details.
To gain a clearer insight into your switch and AP, could you please help us by collecting the following information and sharing it with us via private message for further troubleshooting?
- Tech support information from the switch.
- Diagnostic files from the AP.
- Screenshots of the dynamic VLAN assignment configuration on the NPS.

Hi @Ulthane
Thanks for providing those files.
Upon reviewing your issue, we determined that this is a known issue with 6E APs (including the NWA220AX-6E). Using dynamic VLANs may cause a throughput drop. We will fix this issue in our next firmware release. Stay tuned to for the latest updates.
